SR90-107-KBW

HIGH POWER & HIGH VOLTAGE RESISTORS 2 WATT to 250 WATT, 15KV to 300KV RESISTORS CAPACITORS COILS DELAY LINES SR SERIES RoHS Term.W is RoHS compliant & 260°C compatible Power ratings to 250 watts, voltages to 300KV Wide resistance range: 50KΩ to 5000MΩ Standard Tolerances: ±2, 5, 10, 20% Excellent temperature stability Excellent resistance to voltage pulses Ferrule terminals for clip mounting 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. ↑ D →| H |← ← ↓ | Max.
