Resistors boost working voltages

22 October 2003 Passive Components Surveillance

Design engineers working on high-voltage power applications requiring high pulse load capability in a compact body size can now benefit from a new resistor with a working voltage of 3,5 kV.

TT Electronics Welwyn Components is offering the MH series of UL-approved flameproof resistors that gives an extensive resistance range of 100 kΩ to 1 MΩ at 1% tolerance and a TCR of 100 ppm/°C. Complying with BS EN60065, the metal film resistors are ideally suited to high-voltage power supplies, motor speed control for domestic appliances, barrier resistors in tele-visions and capacitor bleed resistors.

The MH series is available in two standard sizes with limiting element voltages of 1,6 and 3,5 kV with corresponding power ratings from 0,25 to 0,5 W at 70°C ambient. They are rated for operation from -55 to +155°C.
