# RL135601906

**TROQ** · Crystals · SMD3225-4P

RL135601906 from TROQ, in a SMD3225-4P. 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 | XTAL1 | passive | Crystal terminal 1 of the 3.2x2.5x0.7mm 4-pad package, per the pad numbering and symbol in the dimension drawing (8.000MHz to 54.000MHz fundamental). |
| 2 | NC | unconnected | Pad 2 appears in the dimension drawing with no crystal connection in the symbol; the datasheet gives no function, so this is likely a case or no-connect pad. |
| 3 | XTAL2 | passive | Crystal terminal 2 of the 3.2x2.5x0.7mm 4-pad package, per the pad numbering and symbol in the dimension drawing (load capacitance 8pF, 10pF or 12pF). |
| 4 | NC | unconnected | Pad 4 appears in the dimension drawing with no crystal connection in the symbol; the datasheet gives no function, so this is likely a case or no-connect pad. |
