The Difference and Frequency of Use of Thick Film Resistors | Wholesaler, Thick Film Resistor Manufacturer, Custom Design Dual Interface Resistive Components.
Series HVD30, 40, 50 High Voltage Divider Thick Film Resistors are available in a compact TO-220 package with a thick film on ceramic technology that provides the advantage of low inductance. These power resistors are through-hole, radial leaded resistors with a wide resistance value range from 20mΩ to 130KΩ. The radial leaded resistors are available in 0.5%, 1% and 5% tolerance options. These series HVD30, 40, 50 resistors are ideal for use in current limiting, capacitor-discharge, or current measurement circuits in power supplies for telecom and industrial applications.
