# MA251230FR004MZ

**Ever Ohms Tech** · Current Sense Resistors / Shunt Resistors · 2512

MA251230FR004MZ from Ever Ohms Tech, in a 2512. 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 | One end terminal of the MA2512 current-sense resistor, a Ni/Sn-plated terminal 1.05±0.254 mm long (T1) at the end of the 6.350 mm body; the resistor is non-polarised so the two terminals are interchangeable. |
| 2 | 2 | passive | Other end terminal of the MA2512 current-sense resistor, a Ni/Sn-plated terminal at the opposite end of the 6.350 mm body; the resistor is non-polarised so the two terminals are interchangeable. |
