Resistors boost working voltages to 3.5kV

Design engineers working on high-voltage power applications requiring high pulse load capability in a compact body size can benefit from a resistor with a working voltage of 3.5kV.

Design engineers working on high-voltage power applications requiring high pulse load capability in a compact body size can benefit from a resistor with a working voltage of 3.5kV.

TT Electronics Welwyn Components is offering the MH series of UL approved flameproof resistors which gives an extensive resistance range of 100kohm to 1Mohm at 1% tolerance and a TCR of 100ppm/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 televisions and capacitor bleed resistors.

John Graham, Marketing and Sales Director, Welwyn Components said: "Design engineers will find the resistors are especially suited for power applications where space is a premium but able to offer a high limiting element voltage".

The MH series is available in two standard sizes with limiting element voltages of 1.6 and 3.5kV with corresponding power ratings from 0.25 to 0.5W at 70C ambient.

They are rated for operation from -55C to +155C.
