Industry’s highest power film resistors!
RCD’s SR Series is designed for high voltage and/or high
power applications. Film construction has extremely low
reactance enabling superior high-frequency performance.
Insulation is resistant to moisture, solvents, and oil
mediums.
The combination of high power and high voltage provides
new opportunities for design engineers to obtain the utmost
in performance, without the need to assemble chains of
resistors in series. Applications include X-ray equipment,
electron microscopes, and TWT amplifiers.
