UCY2D101MHD

The UCY2D101MHD is a radial-lead aluminum electrolytic capacitor with 100 µF capacitance and a 200 V rated voltage. It is part of Nichicon’s UCY series, designed for miniature size, high ripple current capability and long life in demanding power applications.

Engineered for power supply and ballast applications and qualified to AEC-Q200, the UCY2D101MHD delivers dependable filtering and energy smoothing across a wide temperature range of −40°C to +105°C while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple capability — Low-frequency ripple current 695 mA at 120 Hz and high-frequency ripple current 1.39 A at 100 kHz for robust AC load handling.
• Low dissipation factor — tanδ (DF) max 0.20 measured at 20°C, 120 Hz, supporting efficient energy handling and lower heating under AC ripple.
• Long endurance — 12,000 hours load life at +105°C (series characteristic), providing extended service life in high-temperature environments.
• Compact radial can — Cylindrical package φ12.5 × 25L with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole assemblies.
• Leakage — Specified leakage current of 900 µA to aid in predictable bias performance after application of rated voltage.
• Automotive-grade qualification — AEC-Q200 rated, suitable for applications requiring that qualification.
• Compliance & packaging — RoHS compliant; available in bulk (no terminal forming) and bag packing for flexible inventory handling.

Typical Applications

• Power supplies — Bulk smoothing and decoupling for medium‑voltage rails where 200 V rating and high ripple capability improve stability and thermal performance.
• Ballast and lighting electronics — Energy smoothing in ballast circuits where the UCY series’ high ripple current and long life support continuous operation.
• Automotive electronic modules — Filter and energy-storage duties in automotive systems leveraging the AEC-Q200 qualification and −40°C to +105°C operating range.

Unique Advantages

• High ripple tolerance: Enables reliable AC load handling with specified low- and high-frequency ripple current ratings, reducing the need for parallel parts.
• Extended high-temperature life: 12,000 hours endurance at +105°C provides predictable aging and service life in thermally demanding designs.
• Compact radial package: φ12.5 × 25L can size with 5 mm lead spacing fits space-constrained through-hole boards while keeping installation straightforward.
• Stable electrical performance: Low tanδ (0.20 at 120 Hz) and controlled leakage current support consistent behavior under bias and ripple conditions.
• Automotive-capable: AEC-Q200 rating and wide temperature operation make the part suitable for vehicle electronics that require qualification-driven components.
• RoHS compliance and flexible packing: Environmentally compliant materials and bulk/bag packing options simplify procurement and assembly logistics.
