These resistors are designed specifically for applications that require stable thermo-compression, ultrasonic or epoxy die attachment. This device is built in an 0202 chip outline and is ideal for but not limited to hybrid circuit applications. The WBR1 utilizes our proprietary SiCr thin film resistor. This results in extremely tight tolerances and superior Temperature Coefficient of Resistance (TCR). Tolerance of ±0.1%, with absolute TCR of ±25 ppm/°C is available. The WBR1 offers excellent stability and reliability and is suitable for the most demanding applications. • Aerospace • Medical • Automotive EIA resistance values with 1% tolerance are available for sampling. Please contact Factory.
