Body Size: ⌀18 × 35 mm (typical), 7.5 mm lead pitch
Functional Features: High capacitance density, low ESR, long-life electrolyte, high ripple withstand, pressure-relief vent.
Material Composition: Etched high-purity aluminum anode foil, ethylene-glycol based electrolyte, paper/PP separator, anodized aluminum can, NBR rubber seal, tinned OFC leads.
Structural Characteristics: Cylindrical can, negative stripe marking, top cross/score vent.
Working Principle: Aluminum oxide dielectric formed on anode foil stores charge; electrolyte acts as cathode; charge/discharge through external circuit.
Installation Requirements: Observe polarity, 7.5 mm PCB hole pitch, leave ≥2 mm clearance from neighboring heatsources.
Usage Notes: No reverse voltage; no overvoltage; derate capacitance and life if ambient exceeds 105 °C.
