**YFW** · Bridge Rectifiers · GBU

FGBU1010 from YFW, in a GBU. 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 | Output Anode(+) | power_out | DC output positive terminal (anode) of the GBU bridge rectifier, rated within the FGBU1010 1000 V VRRM and 10.0 A average rectified output current limits. |
| 2 | Input pin (~) | passive | AC input terminal of the bridge rectifier; the datasheet gives no separate per-pin limit beyond the device ratings. |
| 3 | Input pin (~) | passive | AC input terminal of the bridge rectifier; the datasheet gives no separate per-pin limit beyond the device ratings. |
| 4 | Output Cathode(-) | power_out | DC output negative terminal (cathode) of the GBU bridge rectifier, rated within the FGBU1010 1000 V VRRM and 10.0 A average rectified output current limits. |
