KOA Speer Electronics' MF, MFS, and RK series are general-purpose metal film leaded resistors designed for a wide range of applications. These resistors feature a ceramic core with a resistive film and insulation coating, offering reliable performance. The MFS series provides double the power rating of standard body types. The RK series is recognized by UL 1676 and c-UL as a discharge path resistor and meets MIL-R-22684 requirements. They are suitable for automatic machine insertion and are available with lead-free terminations meeting EU RoHS and China RoHS requirements. The MF1/4, MFS1/4, and MFS1/2 series are AEC-Q200 Qualified.
