UCY2D820MHD

The UCY2D820MHD is a radial‑lead aluminum electrolytic capacitor designed for compact power applications. It delivers 82 µF nominal capacitance at a 200 V rating in a miniature φ12.5 × 25 mm can with 5 mm lead spacing.

Engineered for high ripple current and long life, this part is suited to power supplies, ballast circuits and automotive electronics that require robust filtering and energy storage across −40°C to +105°C. It is RoHS compliant and AEC‑Q200 qualified.

Key Features

• Electrical specifications — 82 µF capacitance with tolerance −20%/+20%; polarized; rated at 200 V with tanδ ≤ 0.20 (measured at 20°C, 120 Hz) and specified leakage current of 756 µA.
• High ripple current capability — Low‑frequency ripple current 645 mA at 120 Hz and high‑frequency ripple current 1.29 A at 100 kHz; frequency coefficients provided by the series enable higher ripple handling at elevated frequencies.
• Long endurance at elevated temperature — Rated life of 12,000 hours at +105°C under DC bias plus rated ripple current; endurance criteria include capacitance within ±20% of initial value and leakage current not exceeding initial specified value after life test.
• Wide operating temperature — Specified operating range from −40°C to +105°C for use across demanding thermal environments.
• Compact radial can package — φ12.5 × 25 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm) and available in bulk or bag packing for ease of handling in assembly.
• Standards & compliance — AEC‑Q200 qualified and RoHS compliant, supporting regulated and automotive application requirements.

Typical Applications

• Power supplies and SMPS — Bulk filtering and smoothing where high ripple current and long life are required.
• Ballasts and lighting electronics — Energy storage and ripple management in ballast circuits, as noted in the product series guidance.
• Automotive power electronics — Filtering and decoupling in automotive systems where AEC‑Q200 qualification and an extended temperature range are required.
• DC‑DC converters and power rails — Local energy buffering and ripple attenuation in compact designs.

Unique Advantages

• High ripple endurance: Specified ripple current values at both low and high frequency provide designers with quantifiable performance for thermal and lifetime calculations.
• Long life at elevated temperature: 12,000‑hour endurance at +105°C gives predictable long‑term behavior under continuous DC bias and ripple load.
• Compact footprint: φ12.5 × 25 mm radial can allows space‑constrained placement without sacrificing rated voltage or capacitance.
• Industry qualification: AEC‑Q200 qualification and RoHS compliance simplify inclusion in regulated and automotive BOMs.
• Available in production quantities: Listed as mass production and offered in bulk/no terminal forming or bag packing for flexible supply and assembly workflows.
