UCA2D220MPD

The UCA2D220MPD is a miniature-sized, radial‑lead aluminum electrolytic capacitor in Nichicon’s UCA series, rated at 22 µF and 200 V. It combines high ripple‑current capability with long operational life in a compact φ10×20 mm can with 5.0 mm lead spacing.

Designed for power supply and ballast applications as well as general-purpose electronic circuits, the device operates from −25 °C to +105 °C and is RoHS compliant. Products in this series are scheduled to be discontinued and are not recommended for new designs.

Key Features

• Electrical rating — 22 µF capacitance at a rated voltage of 200 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• High ripple current — Rated ripple current up to 500 mA at 105 °C / 100 kHz, and 250 mA at 120 Hz for robust AC loading.
• Low leakage and controlled dissipation — Leakage current 276 µA (at 20 °C after 1 minute) and tan δ max 0.15 (120 Hz, 20 °C) for predictable circuit behaviour.
• Long operational life — Endurance specified at 10,000 hours at 105 °C for the φ10 case size, supporting sustained high‑temperature operation.
• Compact radial lead package — φ10×20 mm aluminum can, radial lead mounting with 5.0 mm lead spacing, suitable for compact, through‑hole assemblies.
• Wide operating temperature — −25 °C to +105 °C rating for use across common electronic environments.
• Regulatory compliance — Compliant with the RoHS directive.

Typical Applications

• Power supplies — Smoothing, decoupling and bulk energy storage in power supply circuits where 200 V rating and high ripple handling are required.
• Ballasts — Suited for ballast circuits as noted in the product series documentation for handling sustained ripple and elevated temperatures.
• General-purpose electronic circuits — Compact high-voltage decoupling and filtering in through‑hole assemblies and legacy PCB layouts.
• Maintenance and repair of existing designs — Matches legacy form-factor and electrical characteristics for replacement in end-of-life or field-repair scenarios.

Unique Advantages

• High-frequency ripple capability: Rated ripple current of 500 mA at 100 kHz (frequency coefficient 1.00 at 100 kHz) enables reliable performance under high-frequency stress.
• Compact 200 V solution: φ10×20 mm can with 5.0 mm lead spacing delivers a small footprint for 200 V applications, helping preserve board area in dense layouts.
• Predictable electrical performance: Defined tan δ (0.15 max) and leakage current specification (276 µA at 20 °C, 1 minute) for repeatable circuit behaviour and easier design validation.
• Long life at elevated temperature: Endurance rated for 10,000 hours at 105 °C for the φ10 case, supporting long-term operation in warm environments.
• Simple through‑hole integration: Radial lead can package and standard 5.0 mm lead spacing simplify assembly and replacement in existing workflows.
• RoHS compliance: Conforms to RoHS requirements for use in regulated markets.
