UCY2D101MHD3

The UCY2D101MHD3 is a miniature, radial‑lead aluminum electrolytic capacitor featuring 100 µF capacitance at a 200 V rated voltage. Designed for high ripple current and long life, it is intended for power supply and ballast applications and is specified for use across demanding temperature ranges.

Its key attributes—compact φ16 × 20 mm can, high frequency ripple handling, and AEC‑Q200 qualification—make it suitable for applications requiring reliable decoupling and smoothing under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage — 100 µF capacitance rated at 200 V for bulk smoothing and energy storage in power circuits.
• High Ripple Current — Low‑frequency ripple current of 710 mA at 120 Hz and high‑frequency ripple current of 1.42 A at 100 kHz to support heavy AC or switching ripple on DC rails.
• Long Endurance — Rated life of 10,000 hours at +105°C, providing extended reliability under continuous elevated temperature operation.
• Compact Radial Lead Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), suitable for through‑hole PCB implementations where board space is constrained.
• Low Loss & Leakage — Tangent of loss angle (tan δ) 0.20 at 20°C, 120 Hz; specified leakage current 900 µA for predictable low‑current behavior.
• Wide Temperature Range — Operational from −40°C to +105°C to handle a broad set of environmental conditions.
• Polarized, Radial Lead Construction — Standard polarized aluminum electrolytic format for DC smoothing and bulk energy storage.
• AEC‑Q200 Qualified & RoHS Compliant — Designed for high reliability and compliance with RoHS directive requirements.

Typical Applications

• Automotive Power Modules — Bulk smoothing and ripple handling in automotive electronic power supplies and DC‑DC converters, leveraging AEC‑Q200 qualification and the 105°C endurance rating.
• Power Supplies — Energy storage and output filtering for switching regulators and linear supplies where sustained ripple current capability is required.
• Ballast Circuits — Filtering and ripple management in ballast and lamp driver circuits, benefiting from the capacitor's high ripple current performance.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 710 mA (120 Hz) and 1.42 A (100 kHz) reduce stress on the DC rail and improve regulator stability under high ripple conditions.
• Long operational life at elevated temperature: 10,000 hours at +105°C extends maintenance intervals and reduces replacement frequency in thermally demanding applications.
• Compact footprint for through‑hole designs: φ16 × 20 mm can with 7.5 mm lead spacing offers a space‑efficient solution for high‑voltage bulk capacitance.
• Predictable electrical behavior: Specified tan δ (0.20 at 120 Hz) and defined leakage current (900 µA) support accurate power‑supply design and margin calculations.
• Designed for reliability: AEC‑Q200 qualification and RoHS compliance signal suitability for applications requiring component screening and environmental compliance.
