# ECG2WM101M36OTBO

**Yunxing** · Aluminum Electrolytic Capacitors - Leaded · CP_Radial_D18.0mm_P7.50mm

ECG2WM101M36OTBO from Yunxing, in a CP_Radial_D18.0mm_P7.50mm. 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 (anode) of the 100 µF 450 Vdc capacitor; the datasheet requires the correct polarity for DC use because reverse connection causes a short circuit and damage to the capacitor, with lead pitch F 7.5 ±0.5 mm and lead Φd 0.8 mm. |
| 2 | - | passive | Negative lead of the 100 µF 450 Vdc capacitor; the datasheet warns that reverse polarity connection causes a short circuit and damage, with the same lead pitch F 7.5 ±0.5 mm and lead Φd 0.8 mm as pin 1. |
