# ECF1EM101E12OTPO

**Yunxing** · Aluminum Electrolytic Capacitors - Leaded · CP_Radial_D6.3mm_P2.50mm

ECF1EM101E12OTPO from Yunxing, in a CP_Radial_D6.3mm_P2.50mm. 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 | + | passive | Positive lead; the datasheet requires DC use with correct polarity because reverse connection shorts the capacitor and causes damage (p.5, item 1). |
| 2 | - | passive | Negative lead; the datasheet requires DC use with correct polarity because reverse connection shorts the capacitor and causes damage (p.5, item 1). |
