**ROHM Semicon** · Current Sense Resistors / Shunt Resistors · 1206

PMR18EZPFU10L0 from ROHM Semicon, in a 1206. 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 terminal of the 1mΩ-10mΩ current-sense resistor (PMR18, 3.2 x 1.6 mm, bottom termination, 1 W rated at 70°C); land pattern A=1.0, B=4.0, C=1.8 mm. |
| 2 | 2 | passive | Second terminal of the 1mΩ-10mΩ current-sense resistor (PMR18, 3.2 x 1.6 mm, bottom termination, 1 W rated at 70°C); the datasheet specifies 4-probe resistance measurement across the two terminals. |
