MFP Precision Metal Film Resistors YAGEO MFP Precision Metal Film Resistors feature a power rating range of 1/6W to 3W and a resistance tolerance range of ±0.1% to ±0.25%, with ±0.02% and ±0.05% available on request. The MFP Resistors offer ultra-high precision, ultra-high stability, and an ultra-low temperature coefficient. The components are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivative materials onto a carefully treated high-grade ceramic substrate. After a helical groove has been cut in the resistive layer, tinned connecting leads of electrolytic copper are welded to the end-caps. The resistors are then coated with layers of blue lacquer.
