Yageo 91kΩ Metal Film Fixed Resistor 0.5W ±1% MFR50SFTE52-91K

The Yageo MFR Series 91k ohm metal film resistors are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivate 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 coated with layers of blue colour lacquer.

Temperature coefficient of resistance is 50ppm/°C
Maximum Working Voltage is 350V
Operating Temp. Range is 55°C to +155°C
