Thick film chip Vishay resistors target RF applications

Vishay Intertechnology announced that its RCP series of thick film chip resistors for high-power, surface-mount RF applications is now available in the compact 0505, 0603, and 2512 case sizes. The Vishay Dale devices offer very high thermal conductivity for power ratings up to 22 W with active temperature control.

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

RCP series resistors offer a resistance range from 10 Ω to 2 kΩ, tolerance of ± 2 % and ± 5 %, and TCR of ± 100 ppm/°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 with RoHS directive 2011/65/EU and halogen-free according to the JEDEC JS709A definition.
