VPG HD Series

The HD ultra-precision through-hole resistor series from Alpha Electronics offers their extremely precise resistor capabilities in a hermetically sealed package. With a resistance range from 1Ω up to 120kΩ all in a small through-hole package with a pin pitch of 5.08mm ±0.25mm. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to produce resistors with low-temperature coefficients and excellent long-term stability. The Alpha Electronics HD hermetically sealed ultra-precision resistor series have been designed with longer leads to ensure the correct clearance from the PCB is achieved when soldering. It is advised that the resistors are kept over 10mm away from the board surface by using an insulating tube.
