The resistor released today is available in four case sizes from 0402 to 1206 and features a high power rating to 1 W in the 1206 case size (without cooling under the PCB). The PEP offers a wide resistance range from 39 Ω to 900 kΩ, with tolerances down to ± 0.05 %, and operates over a broad temperature range of -55 °C to +155 °C. Combined with very low noise of < -35 dB, a low voltage coefficient of < 0.01 ppm/V, and load-life stability of ± 0.1 % typical for 2,000 hours at +70 °C, the device’s typical specifications exceed the requirements of MIL-PRF-55342G.
The PEP is optimized for precision applications requiring low noise and high stability over time and temperature. End products will include instrumentation, military and avionics guidance systems, automatic test equipment, industrial appliances, and operational amplifiers for test and measurement equipment.
RoHS-compliant, halogen-free, and Vishay Green, the device is sulfur-resistant per the ASTM B809-95 humid vapor test.
