Designing with High Voltage Resistors

Reliable and compact high voltage resistors are essential for a wide range of products from defibrillators to electrostatic paint spray equipment. TT Electronics has extensive expertise in this area and a wide range of products.

Thick-film technology is often used in this area because it allows the fabrication of very high values, and is able to withstand high voltage gradients. It may be configured by design to give low inductance and good linearity across a wide voltage range. A chip or planar high voltage resistor is ideal for compact designs, whilst for voltages above about 30kV, the curved surface of a cylindrical format is often preferred.

High voltage dividers are ideal for voltage scaling before measurement or ADC. The voltage divider has a defined ratio tolerance and tracking TCR, which improves circuit accuracy.
