Product specification
Metal film resistors
5063JD series (space miser)
0.25 to 0.40 W; 1% and 5%
DESCRIPTION
A homogeneous film of metal alloy is deposited on a high grade BALOX 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 a blue lacquer which provides electrical, mechanical, and climatic protection. The encapsulation is resistant to all
cleaning solvents in accordance with “MIL-STD-202E, method 215”, and “IEC 60068-2-45”.
