MM Series High Resistance Resistor SMD Moisture Resistant MELF Resistors

Product Overview

Metal film MELF resistors are surface mount resistors manufactured using metal film technology, offering high stability and precise resistance control.

These products utilize a MELF leadless package, resulting in a compact structure suitable for space-constrained circuits. They also feature excellent solderability and a multi-layer protective coating for effective moisture protection, meeting the demands of high-reliability applications.

Depending on the resistance accuracy, they are available with 3-band (±5%) and 4-band (±2% and below) markings for easy user identification and selection.
