# PMR18EZPFV4L00

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

PMR18EZPFV4L00 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 electrode of the 1206 (3216) PMR18 current-sense chip resistor (terminal width b 1.20 to 0.50 mm ±0.25), rated 1 W at 70°C, 1 to 10 mΩ. |
| 2 | 2 | passive | Second terminal electrode of the 1206 (3216) PMR18 current-sense chip resistor, interchangeable with the first; resistance is measured by the 4-probe method across the terminals. |
