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 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.
