25ppm/C 50ppm/C SMD Resistor Metal Film MELF Resistors MM Series

Product Overview

Metal film (MELF) resistors are surface-mount resistors manufactured using metal film technology, offering excellent stability and precise resistance control.

The products utilize a MELF (Metal Electrode Without Leads) package, resulting in a compact size suitable for space-constrained applications.

They exhibit good solderability and utilize multi-layer coating technology for effective moisture protection, making them particularly suitable for high-reliability circuits.

Furthermore, depending on the resistance tolerance, they are available with 3-ring markings (±5%) and 4-ring markings (±2% and below) for easy identification and selection.
