YC124-FR-0756RL from YAGEO, in a 0402x4. 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 | R1_A | passive | Terminal of resistor R1 on the bottom edge, connected through R1 to pin 5; all four resistors are equal (R1 = R2 = R3 = R4). |
| 2 | R2_A | passive | Terminal of resistor R2 on the bottom edge, connected through R2 to pin 6; R1 = R2 = R3 = R4. |
| 3 | R3_A | passive | Terminal of resistor R3 on the bottom edge, connected through R3 to pin 7; R1 = R2 = R3 = R4. |
| 4 | R4_A | passive | Terminal of resistor R4 on the bottom edge, connected through R4 to pin 8; R1 = R2 = R3 = R4. |
| 5 | R1_B | passive | Opposite terminal of resistor R1 on the top edge, connected to pin 1; rated 1/16 W per array at 70 °C. |
| 6 | R2_B | passive | Opposite terminal of resistor R2 on the top edge, connected to pin 2; rated 1/16 W per array at 70 °C. |
| 7 | R3_B | passive | Opposite terminal of resistor R3 on the top edge, connected to pin 3; rated 1/16 W per array at 70 °C. |
| 8 | R4_B | passive | Opposite terminal of resistor R4 on the top edge, connected to pin 4; rated 1/16 W per array at 70 °C. |
