SILICON THIN FILM CHIP RESISTORS

R1215-S

The R1215-S series of microwave thin film resistors is designed to be used in microwave hybrid circuits for biasing of active components. These devices can be used over the full military temperature range -55°C to +125°C. Quality and workmanship is per MIL-S-883. Level B. Devices are 100% tested, visual inspected and packaged in waffle packs. US Microwaves employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1W/sq to 10.000W /sq. Resistors from 0.1W to x MW range are available.

PROCESS INFORMATION
Resistor Conductor Backside metallization
The resistive material is high stability Tantalum Nitride with low temperature coefficient of resistance, <75ppm/°C typical. For Rsq<10W/sq and Rsq>500W/sq, the resistive material is proprietary. The bonding pads of the resistors are 3m thick, 99.99% electroplated gold with a TiW barrier that withstands 30 min at 400°C in air without loss of adhesion. The backside of the die is metallized with TiW/Au which is compatible with most die attaching methods. Other metallizations are available upon special request.
