Ohmite 83FR511 Wirewound Resistor
Ohmite’s 83FR511 resistor is a high-quality conformal axial terminal wirewound resistor, part of the 80 Series. Designed for precision power applications, it boasts an all-welded construction and a silicone-ceramic conformal coating, ensuring high stability and reliability under demanding conditions. The resistor’s low temperature coefficient and tight tolerance make it suitable for applications requiring precise resistance values and minimal drift over temperature. It is also available in non-inductive versions by adding an “N” to the tolerance code. These resistors are ideal for use in power supplies, motor controls, and other critical circuits where stability and accuracy are paramount.
