Vishay NFR2500004701JA500 metal film resistor
The NFR25 and NFR25H are fusible, non-flammable metal film resistors designed for overload protection without the risk of fire. They feature a homogeneous metal alloy film deposited on a high-grade ceramic body, with tinned copper end-caps welded to the resistive layer. Coated with flame-retardant lacquer, these resistors provide electrical, mechanical, and climatic protection, meeting IEC standards. Suitable for applications in audio and video equipment, they are RoHS compliant, with resistance values ranging from 0.22Ω to 15kΩ and resistance tolerances of ±5%. They feature high temperature coefficients, overload fusing capabilities, and are packaged on reels or in Ammopacks for automated assembly.
