UCY2W820MHD6

The UCY2W820MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial can package, rated 450 V and 82 µF. Designed for high ripple-current applications, it targets power electronics and demanding automotive electronic systems that require long life and stable performance across a wide temperature range.

Featuring AEC-Q200 qualification and RoHS compliance, this polarized radial-lead capacitor delivers elevated ripple handling and a long endurance life for robust DC bias and ripple environments.

Key Features

• High Voltage & Capacitance — Rated at 450 V with 82 µF capacitance, suitable for high-voltage filter and energy-storage roles.
• High Ripple Current — 730 mA at 120 Hz (low frequency) and 1.46 A at 100 kHz (high frequency), enabling effective ripple absorption in both low- and high-frequency power circuits.
• Long Endurance — Rated life of 12,000 hours at +105°C under specified conditions, supporting sustained operation in high-temperature environments.
• Wide Operating Temperature — Specified range from −40°C to +105°C for reliable performance across automotive and industrial temperature extremes.
• Electrical Characteristics — Capacitance tolerance ±20%, tan δ (loss tangent) 0.24 (max at 120 Hz, 20°C), and specified leakage current (1 minute) of 1576 µA for predictable electrical behavior.
• Compact Radial Can Package — 18 mm diameter × 30.5 mm length with 7.5 mm lead spacing (±0.5 mm), offering a small footprint for space-constrained designs.
• Automotive-Grade Qualification — AEC-Q200 qualified and RoHS compliant, aligning with requirements for automotive electronics and other regulated applications.
• Packaging — Supplied bag packed in bulk with no terminal forming, suitable for manual assembly or custom processing flows.

Typical Applications

• Automotive Electronics — Bulk energy storage and ripple filtering in automotive power systems where AEC-Q200 qualification is required.
• Power Supplies — Input/output smoothing and ripple suppression for high-voltage DC power supplies and converters.
• Inverters and Ballasts — High-voltage ripple handling in lighting ballasts and inverter front-ends, consistent with the UCY series design intent.
• Industrial Power Modules — Local energy buffering and filtering in industrial control and power conversion modules operating up to +105°C.

Unique Advantages

• High Ripple Tolerance: Allows designers to handle both low- and high-frequency ripple (730 mA at 120 Hz, 1.46 A at 100 kHz), reducing the need for parallel components.
• Long-Term Reliability: 12,000-hour endurance at +105°C provides predictable aging characteristics for designs targeting long service life.
• Automotive-Grade Assurance: AEC-Q200 qualification and RoHS compliance support use in regulated automotive and industrial environments.
• Compact Form Factor: 18 mm × 30.5 mm radial can offers a small footprint for high-voltage applications where board space is limited.
• Stable Electrical Behavior: Specified tan δ and leakage current values give engineers measurable parameters for thermal and electrical design margins.
