Vishay Intertechnology, Inc. has introduced a new high precision thin film wraparound chip resistor that delivers higher power ratings in smaller case sizes and is designed for industrial, military, and aerospace applications. With a wide resistance value range, this PEP resistor increases reliability by reducing the mechanical stress on solder joints and is optimized for precision applications requiring low noise and high stability over time and temperature. 


This resistor is available in four case sizes from 0402 to 1206 and features a high-power rating of 1 W in the 1206 case size (without cooling under the PCB). The PEP offers a wide resistance range from 39 W to 900 kW, with tolerances down to ± 0.05 %, and operates over a broad temperature range of -55 °C to +155 °C. Combined with 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, this device’s typical specifications exceed the requirements of MIL-PRF-55342G.



  • Load life stability: 0.1 % typical (0.35 % max.) at 2000 h / Pn / 70° C

  • Very low noise < -35 dB and voltage coefficient < 0.01 ppm/V

  • Wide resistance range: 39 Ω to 900 kΩ depending on size

  • Tolerances down to ± 0.05 %

  • Termination: thin film technology

  • Pn: up to 1 W for 1206 size, without cooling under PCB required

  • Sulfur resistant (per ASTM B809-95 humid vapor test)



  • Instrumentation

  • Military and avionics guidance systems

  • Automatic test equipment

  • Industrial appliances

  • Operational amplifiers
