UCA2W100MHD

The UCA2W100MHD is an aluminum electrolytic capacitor in a radial can package designed for general-purpose high-voltage smoothing and energy-storage applications. It delivers a compact form factor with a 10 μF capacitance at a 450 V rating, making it suitable for equipment requiring elevated DC voltage handling in a through‑hole, radial‑lead format.

Key value propositions include high ripple current capability across frequency ranges, a long rated operational life of 12,000 hours at 105°C, and RoHS compliance—attributes that address reliability and regulatory concerns in power and ballast applications.

Key Features

• Electrical Rating — 10 μF capacitance with a 450 V rated voltage and ±20% tolerance to support high‑voltage DC smoothing and filtering tasks.
• High Ripple Current — Rated ripple handling of 160 mA at 120 Hz and 320 mA at 100 kHz, enabling improved performance under AC ripple and high‑frequency loading.
• Long Life at Elevated Temperature — Load life specified at 12,000 hours at 105°C, providing predictable end‑of‑life behavior for designs operating at high ambient temperatures.
• Leakage Current Specification — Initial leakage current limited to 0.04CV + 100 (μA) after one minute at 20°C, per the series specification for predictable standby losses.
• Mechanical & Mounting — Radial lead, can package with 5 mm lead spacing and compact dimensions (L: 2.0 cm × D: 1.25 cm) for easy through‑hole assembly and dense PCB layouts.
• Temperature Range — Rated for operation from −25°C to +105°C to cover typical industrial and power electronics environments.
• Compliance — RoHS compliant.

Typical Applications

• Power Supplies — Bulk smoothing and high‑voltage filtering in power supply rails where 450 V rating and high ripple capability are required.
• Ballast Circuits — Energy storage and ripple suppression in ballast and lamp‑drive applications as noted in the product series guidance.
• General‑Purpose High‑Voltage Electronics — Through‑hole, compact capacitor for general DC filtering and decoupling in high‑voltage equipment.

Unique Advantages

• High Voltage Handling: 450 V rating enables use in elevated DC bus and HV circuits without series stacking.
• Compact Footprint: Small can size (20.0 × 12.5 mm) and 5 mm lead spacing conserve PCB area while supporting through‑hole assembly.
• Designed for Continuous High‑Temperature Operation: 12,000 hour life at 105°C provides extended operational lifetime in hot environments.
• Frequency‑Flexible Ripple Performance: Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies support a range of power topologies.
• Predictable Leakage Behavior: Leakage current governed by the series formula (0.04CV + 100 μA) for consistent design margins.
• Regulatory Compliance: RoHS compliance simplifies use in regulated markets.
