Vishay Intertechnology Inc. has introduced its RCP series of thick film chip resistors for high-power, surface-mount RF applications. According to the company, the Vishay Dale devices are available in the compact 0505, 0603 and 2512 case sizes, and claim to provide very high thermal conductivity for power ratings up to 22W with active temperature control.

RCP series

Optimised for many applications in the automotive, aerospace, military, industrial and telecom markets, the RCP series resistors feature a stable thick film resistive element on an aluminum nitride (AlN) substrate and an epoxy encapsulation. In addition to their case sizes, the existing 1206 case has been enhanced to offer a rating of 2.4W with a standard board mount. The devices feature an operating temperature range from -55°C to 155°C.

RCP series resistors claim to offer a resistance range from 10Ω to 2kΩ, tolerance of ±2 per cent and ±5 per cent, and TCR of ±100ppm/°C. For improved solderability, the devices are available with tin/lead and lead (Pb)-free wraparound terminations over a nickel barrier. The resistors are compliant to RoHS directive 2011/65/EU and halogen-free according to the JEDEC JS709A definition.
