ECHU1C681JX5

PANASONIC · Film Capacitors · 0603

ECHU1C681JX5 from PANASONIC, in a 0603. 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 1 passive First outer electrode of the non-polarized 680 pF (0.00068 µF) 16 V DC stacked PPS film chip capacitor; rated 16 V DC, withstand 150 % of rated voltage for 60 s between terminals.
2 2 passive Second outer electrode of the non-polarized chip capacitor; the land pattern is 0.8 mm (A) × 1.1 mm (C) per pad with 0.8 mm gap spacing, and the reflow limit is 260 °C max, 95 s max above 220 °C.
