UCA2E470MHD

The UCA2E470MHD is a miniature radial-lead aluminum electrolytic capacitor designed for applications that require elevated ripple handling and extended operational life. As a polar, can-style component it delivers 47 µF at a rated 250 V and is specifically suited for power-supply and ballast applications.

Engineered for endurance, the part is rated for 12,000 hours at +105 °C and offers measurable ripple-current capability across low and high frequencies, making it appropriate for general-purpose circuits that need reliable DC smoothing and ripple suppression.

Key Features

• Electrical Performance — Capacitance & Voltage: 47 µF nominal capacitance with a rated voltage of 250 V and tolerance of ±20% (–20% to +20%).
• High Ripple-Current Capability: Rated ripple current of 360 mA at 120 Hz and 720 mA at 100 kHz to support power supply filtering and ripple-bearing circuits.
• Long Life / Endurance: Load-life rating of 12,000 hours at +105 °C under DC bias plus rated ripple current, supporting extended service intervals in continuously powered systems.
• Temperature Range: Operates from –25 °C to +105 °C to cover typical industrial and commercial operating environments.
• Mechanical / Packaging: Radial lead, can-type package with 5.0 mm lead spacing and physical dimensions L: 2.5 cm × D: 1.25 cm, suitable for through-hole PCBs.
• Polarized Design: Electrolytic, polarized capacitor for DC smoothing and bulk energy storage in power circuits.
• RoHS Compliant: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), meeting environmental regulatory requirements.

Typical Applications

• Power Supplies: Bulk smoothing and ripple suppression in DC power rails where 250 V rating and high ripple capability are required.
• Ballasts: Filtering and energy storage in ballast circuits that demand durable capacitors with long operational life at elevated temperatures.
• General-Purpose Electronics: Through-hole designs requiring a compact, polarized capacitor for decoupling, filtering, or charge storage.

Unique Advantages

• High ripple-current handling: Specified ripple currents at both 120 Hz and 100 kHz enable stable performance across common ripple frequency ranges.
• Extended high-temperature life: 12,000-hour endurance at +105 °C helps reduce maintenance and replacement frequency in continuously operating equipment.
• Through-hole robustness: Radial lead, can package with 5.0 mm lead spacing integrates easily into standard PCB assemblies for reliable mechanical retention.
• Compact footprint: Small physical dimensions (L: 2.5 cm × D: 1.25 cm) provide a space-efficient solution for designs with constrained board area.
• Regulatory compliance: RoHS conformity supports deployment in regulated markets without additional compliance steps.
