# 2TO412000CWBC

**JYJE** · Crystal Oscillators · SMD2520-4P

2TO412000CWBC from JYJE, in a SMD2520-4P. 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 | EN/NC | input | Enable control (N/C or Tri-state): leaving it unconnected or enabling it permits oscillator output, and the datasheet gives no logic thresholds. |
| 2 | GND | power_in | Ground connection for the oscillator. |
| 3 | OUT | output | Clock output driving 10 TTL or 15pF HCMOS load with 10nS max rise/fall time. |
| 4 | VDD | power_in | Supply voltage pin, 1.8V to 5.0V ±10%. |

## CAD (KiCad official)

- Symbol: `2TO412000CWBC`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `2to412000cwbc-etched.step` / `2to412000cwbc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2to412000cwbc.step` / `2to412000cwbc.glb` are the bare package body.
