SWXSEBCVE0-26.298200

Starwave(思大) · IC · HC-49S

SWXSEBCVE0-26.298200 from Starwave(思大), in a HC-49S. 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 2-lead HC-49S unit (3.290 MHz, 20pF load or as specified, drive level 1500 µW); the drawing shows two leads 4.88±0.25 mm apart and does not label them.
2 XTAL2 passive Crystal terminal 2 of the 2-lead HC-49S unit (3.290 MHz, 20pF load or as specified, drive level 1500 µW); the drawing shows two leads 4.88±0.25 mm apart and does not label them.
