UCA2C470MHD

The UCA2C470MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCA series, rated 47 µF at 160 V. It is designed for high ripple-current handling in compact can packages and is intended for use in power supply and ballast applications where sustained ripple and long life are required.

Key value propositions include high ripple-current capability at elevated temperature, long endurance at 105°C, and a compact φ12.5 × 20 mm radial-can form factor. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 160 V and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High Ripple-Current Performance — Rated ripple current 725 mA at 105°C/100 kHz; frequency-dependent ripple behavior includes 362.5 mA at 120 Hz.
• Long Life / Endurance — Specified load-life endurance of 12,000 hours at 105°C under rated DC bias plus rated ripple current.
• Thermal & Operating Range — Operating temperature range from –25°C to +105°C, suitable for sustained elevated-temperature operation.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) max 0.15 at 120 Hz and 20°C; measured leakage current listed as 400.8 µA (after 1 minute at rated voltage, 20°C).
• Compact Radial Package — Case size φ12.5 × 20 mm, lead spacing 5.0 mm, radial-can package; polar capacitor, sold in bulk with no terminal forming.
• Regulatory — Compliant with the RoHS directive.

Typical Applications

• Power Supplies — Bulk and output filtering where 160 V rating and high ripple current reduce voltage ripple and support steady DC rail performance.
• Ballasts — Filtering and energy storage in ballast circuits that require high ripple endurance and elevated-temperature operation.
• General-Purpose Power Electronics — Compact radial-can solution for space-constrained power circuits needing long-life electrolytic capacitance.

Unique Advantages

• High ripple-current capacity: 725 mA at 105°C/100 kHz enables effective smoothing under high-frequency ripple loads.
• Extended endurance at high temperature: 12,000-hour rated life at 105°C supports longer service intervals in demanding thermal environments.
• Compact footprint: φ12.5 × 20 mm radial-can package and 5 mm lead spacing save PCB area while providing robust capacitance and voltage rating.
• Predictable electrical characteristics: Specified tan δ (0.15) and defined leakage current support accurate margining in power designs.
• RoHS compliant: Meets RoHS requirements for restricted substances.
