MPR24/191K/0.1 Yageo

MPR24 Vishay BCcomponents 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.
