ULD1H470MED

The ULD1H470MED is a miniature, radial-lead aluminum electrolytic capacitor designed for long-life power applications. It provides 47 µF capacitance at a 50 V rating in a compact can-style package suited to space-constrained designs.

Targeted for power-supply use in LED lighting and general-purpose electronics, this capacitor combines long-term endurance at elevated temperature with polarized radial mounting for board-level power filtering and decoupling.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, specified at 120 Hz and 20°C.
• Long-Life Endurance — Designed to withstand a load life of 10,000 hours at +105°C under DC bias plus rated ripple current, supporting reliable operation in elevated-temperature environments.
• Operating Temperature Range — Rated for −40°C to +105°C to cover a wide range of industrial and commercial operating conditions.
• Package & Mounting — Radial lead, can-style construction with compact size (1.1 × 0.63 cm) and 2.5 mm lead spacing for easy through-hole assembly.
• Ripple Current Capability — Specified ripple current of 133 mA at 120 Hz and 190 mA at 100 kHz, enabling use in filtering and smoothing tasks across low- and high-frequency domains.
• Polarized Design — Standard polarized aluminum electrolytic suitable for DC power circuits.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• LED Lighting Power Supplies — Long-life endurance at 105°C and 50 V rating make it appropriate for smoothing and energy storage in LED driver circuits.
• General-Purpose Power Filtering — Polarized aluminum electrolytic performance for decoupling and bulk capacitance in compact power supplies and converters.
• Space-Constrained Board Designs — Miniature can package and small footprint suit designs where PCB area and component height are limited.

Unique Advantages

• Proven High-Temperature Reliability: 10,000-hour load-life rating at +105°C provides predictable endurance for thermal-stressed power electronics.
• Compact Footprint: Small 1.1 × 0.63 cm can and narrow lead spacing enable higher component density and compact assemblies.
• Versatile Ripple Handling: Defined ripple current ratings at both 120 Hz and 100 kHz support a range of switching and linear power topologies.
• Through-Hole Robustness: Radial-lead, can-style construction simplifies mechanical mounting and replacement in repairable designs.
• Regulatory Compliance: RoHS compliance aligns with environmental and materials requirements for commercial electronics.
