Packaged in a φ12.5 × 20 mm radial can with 5 mm lead spacing, this part is offered in bulk/bag packaging and is in mass production, delivering a compact, production-ready solution for designers requiring reliable electrolytic performance in -40°C to 85°C environments.

Key Features

• Capacitance & Tolerance — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable bulk storage and filtering behavior.
• Voltage & Polarization — Rated for 50 V and polarized for correct DC circuit placement in power and audio paths.
• Ripple Current Capability — Rated ripple current of 760 mA at 120 Hz (low frequency) and 1.14 A at 10 kHz (high frequency), supporting both low- and high-frequency ripple conditions.
• Low Leakage — Leakage current specified at 705 µA, consistent with initial-condition limits for sensitive circuits.
• Reliability & Lifetime — Endurance specified at 2000 hours at 85°C with restored performance meeting capacitance and leakage criteria.
• Operating Temperature — Designed for operation from -40°C to 85°C, suitable for typical audio and industrial ambient ranges.
• Form Factor & Mounting — Radial lead can, φ12.5 × 20 mm, 5 mm lead spacing; compact footprint for through-hole implementations.
• Packaging & Production — Supplied in bulk/bag packaging and available in mass production quantities for volume assembly needs.

Typical Applications

• Audio Equipment — Bulk filtering and decoupling in audio power supplies and amplifier circuits where 470 µF at 50 V is required.
• Power Supply Filtering — Smoothing and energy storage for DC rails in consumer and professional audio devices.
• General Electronics — Through-hole radial mounting for repair-friendly or legacy PCB designs that require reliable electrolytic capacitance.

Unique Advantages

• Designed for audio systems: Series specification cites suitability for audio equipment, aligning electrical characteristics with common audio power needs.
• Dual-frequency ripple performance: Specified ripple current at both 120 Hz and 10 kHz supports handling of low- and high-frequency ripple components without guesswork.
• Compact radial package: φ12.5 × 20 mm can with 5 mm lead spacing provides a space-efficient through-hole solution for board layouts.
• Predictable leakage behavior: Leakage current value of 705 µA gives designers a concrete parameter for bias and discharge calculations.
• Rated endurance at elevated temperature: 2000-hour life at 85°C enables designers to plan for long-term performance in warm operating environments.
• Production-ready supply: Bulk/bag packaging and mass production status support supply chain needs for production runs.
