MF25-3K57 Netech

MF series are a group of metal film fixed resistors applying high Aluminum content base material vacuum sputtered by Ni Cr alloy and excellent heat and wet proof special resin for protective coating. Those resistors are manufactured through integrated automatic production system and then have good stable and uniform property.Furthermore, they show excellent performance regardiess open in air.
