Thin film wraparound chip resistor is available in four case sizes

Vishay Intertechnology has introduced a thin film wraparound chip resistor that serves industrial, military and aerospace sectors. The Vishay Sfernice PEP is available in four case sizes from 0402 to 1206.

The chip resistor delivers 1.0W, with resistance from 39 Ohm to 900 kOhm. It offers, said Vishay Intertechnology, the widest resistance value range on the market, and higher power ratings in smaller case sizes than competing devices. These characteristics enable miniaturisation and increases reliability by reducing the mechanical stress on solder joints, added the company. 

The PEP resistor features a high power rating to 1.0W in the 1206 case size (without cooling under the PCB).  In addition to a wide resistance range with tolerances down to ± 0.05 per cent, the resistor operates over a broad temperature range of -55 to +155 degrees C. Combined with very low noise of less than -35 dB, a low voltage co-efficient of less than 0.01 parts per million per V (ppm/V) and load life stability of ± 0.1 per cent typical for 2,000 hours at +70 degrees C, the device’s typical specifications exceed the requirements of MIL-PRF-55342G. 

The PEP is optimised for precision applications requiring low noise and high stability over time and temperature, advised Vishay. End products will include instrumentation, military and avionics guidance systems, automatic test equipment, industrial appliances, and operational amplifiers for test and measurement equipment. 

The resistors are RoHS-compliant, halogen-free and sulphur-resistant per the ASTM B809-95 humid vapour test. 

Samples and production quantities of the PEP resistor are available now, with lead times of 16 weeks. 

Vishay manufactures a large portfolio of discrete semiconductors and passive electronic components that are used in designs in the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
