Resistor - PR03, Vishay BC, 3 Watt, Power Metal Film
High quality metal film resistors from Vishay / BC Components. PR03 resistors are rated for 3W but have a compact 5.2x19.5mm package. These resistors look great in vintage and vintage-style builds and have been used in high-end Marshall amplifiers and other audio equipment.
Construction:
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.
Features:
- High power in small packages
- Defined fusing characteristics
- Technology: Metal Film
- ±5% tolerance
- Meets active and passive flammability requirements as defined in IEC 60115-1
RoHS Compliant
