Capacitor discharge / balance resistor is quick and easy to mount

Arcol has announced availability of the RW wire-wound discharge resistor. The resistor is designed for quick and easy mounting on to capacitors typically to be used as a discharge or balancing resistor. Discharge resistors are routinely connected across large value output capacitors found in electrical and electronic equipment which may store dangerous levels of energy after the equipment has been turned off. Providing a safe discharge avoids any hazardous conditions when connecting other equipment or during service or repair. Balancing resistors are used when a number of capacitors are connected in series to ensure voltages across any individual capacitor does not exceed its maximum rating. The RW discharge resistor provides simple to fit screw mounting, is rated up to 22W, has a wide operating temperature range and is RoHS compliant. Three power ratings are available 10W, with ohmic value range of 1-15kohm, 13W with values from 1-2kohm and 22W from 1-33kohm Key specifications include operating temperature -55C to +200C, over-load / over-voltage ten times rated power for five seconds, de-rating 80C to 175C linearly, tolerance (code) ±1% (F), ±5% (J), temperature coefficient 30ppm and 100ppm/C as standard, says the company.
