Ultra Precision Leaded Resistors
FEATURES
Ultra high precision resistors
Ultra high stability
Ultra low temperature coefficient.
APPLICATIONS
Test and measurement
Telecom.
DESCRIPTION
A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive
layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated with lacquer which
provides electrical, mechanical, and climatic protection.
