Vishay PR03-820 Ohm 3W

Power Metal Film Leaded Resistor, 3W. 0411 size (5,2 x 19,5mm). These metal film resistors look and sound great in vintage and vintage-style builds and have been used in high-end Marshall amplifiers and other audio equipment.

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 or copper-clad iron are welded to the end-caps. The resistors are coated with a red, non-flammable lacquer which provides electrical, mechanical and climatic protection. This coating is not resistant to aggressive fluxes and cleaning solvents. The encapsulation is resistant to all cleaning solvents in accordance with IEC 60068-2-45.
