Reduced solder joint stress

Vishay Intertechnology has introduced a new high precision thin film wraparound chip resistor for industrial, military and aerospace applications. Vishay states the Sfernice PEP offers the widest resistance value range on the market and delivers higher power ratings in smaller case sizes than competing devices, which enables miniaturization and increases reliability by reducing the mechanical stress on solder joints.

The resistor is available in four case sizes from 0402 to 1206 and features a power rating to 1W in the 1206 case size (without cooling under the PCB). The PEP offers a resistance range from 39Ω to 900kΩ, with tolerances down to ± 0.05 per cent.

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