Kyocera AVX has expanded its CR series of high-power chip resistors with a device that handles 2.5 W in a small 0603 package. Designed to enable the miniaturization of RF power amplifiers, the 0603 resistor overcomes size constraints and enhances thermal management by incorporating a high thermal conductivity substrate and maximized heat sink grounding area.
Chip resistors in the CR series are non-magnetic, qualified to MIL-PRF-55342, and deliver reliable performance in a variety of communications, instrumentation, test and measurement, military, and defense applications. They feature thin-film resistive elements, aluminum nitride substrates, and silver terminals.
The resistors are available in eight chip sizes from 0603 to 3737, with standard resistive values of 100 Ω and 50 Ω and tolerances as tight as ±2%. They offer capacitance values ranging from 0.3 pF (0603) to 6.0 pF, power handling up to 250 W, and operating temperatures from -55°C to +150°C.
Chip resistors in the CR series are available from Mouser, DigiKey, and Richardson RFPD.
