YLRY12-3-220F

Shenzhen Yezhan Elec · Current Sense Resistors / Shunt Resistors · 2512

YLRY12-3-220F from Shenzhen Yezhan Elec, 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 First terminal of the 2512 YLRY12 standard-terminal current-sense resistor (3W rated at 70℃, 220mΩ ±1% per the MPN code), a non-polarized end electrode with 6.4mm overall width W and 3.2mm height C.
2 2 passive Second terminal of the 2512 YLRY12 standard-terminal current-sense resistor, a non-polarized end electrode interchangeable with the first, operating from -55℃ to 170℃.
