-- RESISTORS
Name:METAL FILM RESISTORS
Type:

Description:
The MF series Metal Film Resistors are manufactured using vacuum sputtering system to deposit multiple layers of mixed metals and passivative materials onto a carefully treated high grade ceramic substrate, the resistors are coated with layers of light-blue lacquer. The MF series emcompasses an unusually broad selection of power rating (1/8W,1/4W,1/2W,1W,2W at 70°C),tolerance (±0.01%,±0.05%,±0.1%,±0.25%,±0.5%,±1%)in all their combinations with full MIL-R-10509, JIS-C5202 performance. Packaging in bulk, taped and reel, the cut and formed supplied.
