Model RCH25S47000JS06
Description Vishay Sfernice 25W RCH25 series resistors suitable for RCH 25 W chassis series are designed to be mounted on heat sinks. Capable of withstanding high short-term overload with thick coating and non inductive low heat radiation, it is particularly suitable for high-frequency operation and circuit cutting, similar to RH wire wound resistors. Rated power: | -------- \ - chassis installation | 25 W \ - non chassis installation | 4 W maximum operating voltage: | 550 V effective value tolerance: | ± 5% temperature coefficient: |<1 Ω: | ± 250 ppm/° C ≥ 1 Ω: | ± 150 ppm/° C thermal resistance: | 1.4 ° C/W dielectric strength: | 3500V operating temperature: | -55-+125 ° C size (length x width x height): | 28 x 27.5 x 15 mm size (millimeters) - L | W | H | P | F | T | S | Ø D screws not provided 28 | 14 | 27.5 | 18.3 | 18.3 | 19.8 | 7.7 | 3.2 M3 size - Sfernice series| RCH 5 | RCH 10 | RCH 25 | RCH 50 L | 16.6 | 19 | 28 | 50 W | 9 | 11 | 14 | 15.5 H | 16.4 | 20.6 | 27.5 | 29.4 P | 10.2 | 12.7 | 18.3 | 33 F | 11.3 | 14.3 | 18.3 | 39.7 T | 12.5 | 15.9 | 19.8 | 21.4 S | 5.3 | 5 | 7.7 | 8 Ø D | 2.4 | 2.4 | 3.2 | 3.2 | M2 | M2 | M3 | M3 Main Features - Overload Duration| RCH25 | RCH50 | BDS100 | BDS250 1 s | 375W | 750W | 200W | 1500W 2 s | 300W | 600W | 150W | 1250W 5 s | 125W | 250W | 125W | 1000W 10 s | 75W | 150W | 100W | 750W For every one degree increase in ambient temperature above 25 ° C, the allowable overload is reduced by 1%. The main feature table is only applicable to resistors appropriately installed on heat sinks, with a thermal resistance of 1 ° C/W at rated powers of 25 and 50W, 0.7 ° C/W at rated power of 100W, and 0.28 ° C/W at rated power of 250W. This data is only valid when hot oil grease is used and the resistor is correctly tightened by the mounting screw. Tightening torque - RCH25 | RCH50 | BDS100 | BDS250 0.7Nm | 1Nm | 2Nm | 2Nm
