Electronics chip resistor wraparound

VISHAY INTERTECHNOLOGY Sfernice PEP  high precision thin film wraparound chip resistor offers a wide resistance value range and serves industrial, military and aerospace applications. Devices deliver higher power ratings in smaller case sizes than competing components, which enables miniaturization and increases reliability by reducing the mechanical stress on solder joints. Product is available in four case sizes from 0402 to 1206 and features a high power rating to 1W in the 1206 case size (without cooling under the pcb). Device offers a wide resistance range from 39Ω to 900kΩ, 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 < -35dB, 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.
