SWXJBBCVE0-12.000000

Starwave(思大) · IC · HC-49S-SMD

SWXJBBCVE0-12.000000 from Starwave(思大), in a HC-49S-SMD. 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 First crystal terminal (left pad in the drawing); 12.000 MHz unit with 18 pF load capacitance, 1~500 µW drive level (100 µW typical).
2 XTAL2 passive Second crystal terminal (right pad in the drawing); non-polarized, interchangeable with the other terminal, 7 pF max shunt capacitance (C0).

CAD (KiCad official)

  • Symbol: SWXJBBCVE0-12.000000
  • Footprint: Crystal:Crystal_SMD_HC49-SD
  • 3D model: HC-49S-SMD (KiCad packages3D, STEP)
  • 3D model files: swxjbbcve0-12-000000-etched.step / swxjbbcve0-12-000000-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); swxjbbcve0-12-000000.step / swxjbbcve0-12-000000.glb are the bare package body.
