Melf Metal Film Resistors

Yageo MMF Series

Melf Metal Film Resistors - MMF Series

Yageo's MMF series Melf Metal Film Resistors are manufactured using a vacuum sputtering system to deposit multiple layers of mixed metal alloys and passivative materials onto a carefully treated high grade ceramic substrate, SMD enabled structure. The resistors are coated with layers of blue color lacquer.

The MMF series meet the requirement for long-term stability, moisture resistance, reliability, and temperature cycling in lead-free assembly processes. Working voltages can be applied from 150 V up to 350 V, and the operating temperature is -55°C to +155°C.

Features

  • Suitable for reflow and wave soldering
  • Metal plate terminals
  • Meets IEC 60115-1
  • Marking: blue body color with four color-coded bands
  • Products with lead-free terminations meet RoHS

Specifications

  • Power rating: 1/4 W, 1/2 W, and 1 W
  • Resistance range: 1~1 MΩ
  • Resistance tolerance: ±0.1% and ±1%,
  • TCR: ±25 ppm/°C, ±50 ppm/°C, and ±100 ppm/°C
