Product Overview
The Vishay WSR2 series are surface mount, power metal strip resistors. The WSR2 series have a low resistance values ranging from 1mohm to 1ohm and power rating of 2W. These resistors use solid metal nickel chrome or manganese copper alloy as a resistive element with low TCR. The WSR2 series are ideal for all types of current sensing, voltage division and pulse applications.
- Automotive grade AEC-Q200 qualified
- Compact 4527 package size
- ±0.5% and ±1% tolerance
- Moulded high temperature encapsulation
- Very low inductance 0.5nH to 5nH
- Excellent frequency response to 50MHz
- Low thermal EMF (<lt/> 3μV/°C)
- ±750ppm/°C, ±600ppm/°C, ±450ppm/°C, ±300ppm/°C, ±110ppm/°C, ±75ppm/°C TCR values available
- Operating temperature range -65°C to +275°C
- Resistant to thermal and mechanical shock, extreme temperatures, humidity and vibration
