**YAGEO** · Current Sense Resistors / Shunt Resistors · MELF-0207

MMP100JR-10R from YAGEO, in a MELF-0207. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First end-cap terminal of the non-polarized MMP100 (1W at 70 °C) resistor, with a 0.5 mm minimum end-cap length C and a suggested reflow pad of 2.0 mm min length by 3.0 mm min width. |
| 2 | 2 | passive | Second end-cap terminal of the non-polarized MMP100 resistor, interchangeable with the first and spaced 3.0 ±0.1 mm pad-to-pad (P) for reflow, with a maximum working voltage of 350V. |
