1. SMD enabled structure with excellent solderability
2. Conformal multi-layer coating against humidity
3. 5% tolerance uses 3-band coding; 2% and below use 4-band coding
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.
