JER1206F1R000

jieerrui · Current Sense Resistors / Shunt Resistors · 1206

JER1206F1R000 from jieerrui, 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 One resistor terminal of the 1206 alloy current-sense chip (3.20x1.60 mm body, 0.50±0.20 mm electrode width, 1W rated at 70°C ambient, derated linearly to 170°C).
2 2 passive Other resistor terminal of the 1206 alloy current-sense chip (non-polarized, interchangeable with the other terminal; operating range -55°C to +170°C).
