Thick Film Chip Resistors on AlN Substrates

Vishay Intertechnology, Inc. introduced a new series of thick film chip resistors for high-power, surface-mount RF applications. Offered in the compact 1206 case size, the Vishay Dale RCP series devices feature a power rating of 1 W at +70 °C with a standard board mount and up to 11 W with active temperature control.

Optimized for high-power aerospace, military, industrial, and telecom systems, RCP series resistors feature a stable thick film resistive element on an aluminum nitride (AlN) substrate and an epoxy encapsulation. Offering very high thermal conductivity in a small package size, the RCP series features 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 to RoHS directive 2011/65/EU and halogen-free according to the JEDEC JS709A definition.

Samples and production quantities of the RCP are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery only starts at $ 1.90 per piece in 1,000-piece quantities.
