Highest power 0603 resistor delivers high-reliability performance

Kyocera AVX has expanded its selection of CR Series high-power chip resistors by adding the industry’s highest power 0603 resistor.

CR Series high-power chip resistors are non-magnetic, RoHS compliant, qualified to MIL-PRF-55342, manufactured in ISO-9001 facilities, and proven to provide high-reliability performance in various high-power and high-frequency applications. The new high-power resistors, developed to facilitate the miniaturisation of RF power amplifiers, also address common size constraints and enhance thermal management thanks to a high-thermal-conductivity substrate and maximised heat sink grounding area.

The high-power chip resistors feature proprietary thin film resistive elements, aluminium nitride substrates, and silver terminals. They are currently available in eight chip sizes extending from 0603 to 3737 with two standard resistive values (100-Ohm and 50-Ohm), capacitance values spanning 0.3pF to 6pF, a power handling capability of up to 250W, rated operating temperatures extending from -55C to +150C, and resistive tolerance as tight as ±2%. They are also available with non-standard values as low as 10-Ohm and as high as 200-Ohm and with standard tape and reel or anti-static waffle packaging. The new resistor is rated for 0.3pF and up to 2.6W.

“We’re thrilled to introduce the industry’s highest power 0603 resistor as part of our proven CR Series high-power resistor product line,” said Mohammed Abu-Naim, RF product manager, Kyocera AVX. “These new miniaturised resistors will enable the continued miniaturisation of products, including RF power amplifiers that have long relied on larger components to satisfy power demands.”

Ideal applications for CR Series high-power resistors extend throughout the communications, instrumentation, test and measurement, and defence markets and include high-power RF amplifiers, dummy loads, shunts used for power measurement, and discrete resistive baluns used for impedance matching.
