Product Specifications
It varies by model. The LNF-LNC4_8G achieves 1.5K average noise temperature with 39 dB gain. The LNF-LNC1.2_3.5A achieves 1.3K with 31 dB gain. Contact us with your frequency range and application and we’ll identify the right model.
Bias requirements vary by model. The LNF-LNC4_8G requires Vds=0.6V, Ids=13mA. The LNF-LNC4_8F_LG requires 0.7V, 10mA. Full bias specifications are in the individual datasheets.
All cryogenic LNAs are tested at 4K before delivery and are guaranteed for reliable cryogenic operation.
Yes. The room temperature range covers 4–115 GHz with noise temperatures around 40K. The LNF-LNR4_8F covers 4–8 GHz with 44 dB gain and 40K noise temperature.
Yes, in the 4–8 GHz and 4–12 GHz ranges, with insertion loss around 0.17 dB. Magnetic shielding is available as an option.
Ordering & Service
Yes, all models can be procured and delivered across India. Some require a self-declared end-user declaration.
The amplifiers themselves cannot be customised, but additional magnetic shielding can be provided if needed.
Share the model number and quantity you’re interested in, or describe your application, we’ll provide the relevant datasheet.
Once a model is identified and quoted, we need a formal purchase order to proceed. An order acknowledgment with estimated delivery time follows.
Typically 8–12 weeks.
Yes. We’ll do our best to source and support related requirements.
Ordering & Service
Most models have no MOQ. Some special models do, and this is noted in our quote.
It depends on the model. Some are available immediately. Standard models typically deliver in 3–5 weeks. Certain special models require 12–15 weeks.
Yes. We have an in-house diagnosis and service lab with qualified technicians for application and technical support.
Technical Parameters
Selection involves four areas:
Electrical: Power supply requirements, peak measurement, response time, di/dt and dv/dt.
Mechanical: Aperture size, dimensions, mass, materials, mounting, and vibration tolerance.
Thermal: Current profile versus time, maximum RMS measurement, thermal resistances, and cooling.
Environmental: Vibration, operating temperature range, and proximity to other conductors or magnetic fields.
Some applications add complexity — electromagnetic interference, significant common-mode voltage transients, mechanical shock, special isolation requirements, or specific standard compliance. In these cases, testing in the actual application environment is the best approach. If that’s not feasible, share a wiring diagram and detailed description of operating conditions with us and we’ll work through it.
Also called continuous or rated current/voltage, the maximum permanent thermal current or voltage the transducer can carry continuously without exceeding its specified temperature. Measured with a 50Hz sinusoidal signal.
The region limited by the maximum measurable peak value in non-steady state. Closed-loop transducers can measure higher values if the current is very brief and non-repetitive — this is the dynamic measuring range, limited by peak current. For open-loop transducers, the measuring range is linked to magnetic circuit saturation or the voltage output stage limit.
Voltage and current sensors with current output need a burden resistor (RB or RM) to obtain the correct measurement. For closed-loop sensors, the burden resistor defines the current-to-voltage ratio for your application. Current output signals are less susceptible to external interference — useful when the sensor and control electronics are physically separated.
The minimum value is set for thermal protection of the output stage (0Ω for some types). The maximum value is set to preserve the measurement range — a resistor above the specified maximum reduces the range. If you need values outside the datasheet range, contact us with your application conditions and we’ll calculate the right values.

Product Specifications
It applies a high voltage to a device to verify that its insulation can withstand over-voltage conditions without breaking down. Depending on the model, it can also measure insulation resistance, ground bond, and leakage current. Used for safety certification across BIS, IEC, UL, and other standards.
The 95X Series covers up to 11kV AC and 15kV DC. The V7X Series covers up to 5kV AC/DC.
Yes. Select models include ground bond (protective earth) test capability alongside AC/DC hipot, insulation resistance, and leakage current measurement.
Yes. The 964i HV Scanner interfaces with both the V7X and 95X series. Vitrek hipot testers can also directly control up to 256 test points, expandable to 640 using a PC with QuickTest Pro software.
Yes. They come with RS-232 and GPIB ports and are compatible with QT Enterprise software.
Yes, test enclosures designed for use with the hipot testers are available.
Service & General
Annually, either at a NABL-accredited lab or by sending the instrument to Globetek.
Yes, we have a service lab and carry necessary spare parts.
3–4 weeks from order.
No.
General & Ordering
Share your requirements with us. We work with Ironwood to provide a quote covering the non-recurring engineering fee, socket cost, and lead time. Once a purchase order is processed, design is completed in 1–2 weeks for your approval. Manufacturing and shipping take 4–6 weeks from design sign-off. A STEP file is provided for approval before production begins — if changes are needed, we set up a call between you and the Ironwood design team.
Standard sockets: 3–4 weeks. Custom sockets: 6–8 weeks.
For most queries, we handle this through Globetek in consultation with Ironwood. For complex custom design work, we set up a direct call between your team and Ironwood’s engineers.
We provide after-sales support, and a formal design approval process is in place for custom orders. Contact us and we’ll work through it.
Yes. We send the socket to Ironwood for failure analysis. Depending on feasibility, they will either repair or replace it.
Technical Specifications
Yes. Share your mechanical specifications and application requirements and we’ll provide a quote and lead time.
Yes, though a custom design may be required for specific ATE setups.
Yes, and adapters to bring signals out are also available.
Up to 600 balls is straightforward. Above that, we’d need to discuss with the Ironwood team.
Epoxy mount sockets are the closest alternative.
Elastomer sockets give the best mutual inductance performance, but insertion cycle life is lower than spring pin sockets. Replacement elastomers are available to extend the useful life.
Ironwood is working on extending socket solutions for LPDDR6. Contact us for the latest status.
They let you socket BGA devices without performance loss, board space overhead, or solder. The socket is positioned with a precision alignment tool and epoxied in place. Special grooves provide additional retention, and the contactor can be replaced after hundreds of cycles.
Durability & Maintenance
Three things matter most: follow the manufacturer’s torque specifications, keep the contacts clean, and respect the temperature cycling limits for the socket technology you’re using.
Frequency: Light cleaning every 25–50 cycles. Thorough cleaning every 100 cycles.
Light cleaning (tape method):
- Remove socket from board
- Wrap tape adhesive-side out around fingertip
- Roll over the elastomer surface — lifts debris without sticking
- Clean both sides (remove elastomer guide for the second side)
Thorough cleaning:
- Remove elastomer from guide
- Scrub gently with a stiff nylon brush and a 50/50 DI water + IPA mix
- Blow dry with clean air and allow to fully dry
- Finish with the tape method
Do not submerge the elastomer or apply liquids directly — it absorbs fluid and deforms.
Dry cleaning: Remove socket, brush and vacuum solder pads and probe tips. Rotate and repeat. Clean guides and reassemble. Store in dust-free enclosures. Avoid compressed air above 30 psi.
Wet cleaning: Disassemble contacts, place in IPA-filled beaker, ultrasonic clean at 40 kHz, 22°C for 45–60 minutes. Dry with ≤30 psi air, bake at 65°C for 30 minutes. Reassemble in correct orientation.
Solder ball residue builds up inside the Grypper after each insertion. Clean approximately every 20–25 insertions to prevent buildup from affecting performance.
