UCYW6120MPD

The UCYW6120MPD is a miniature aluminum electrolytic capacitor from Nichicon’s UCY series designed as a radial‑lead, high‑reliability solution for power applications. It offers 12 µF capacitance at a 420 V rated voltage in a compact φ10 × 20 mm can with 5.0 mm lead spacing.

Targeted at power supply and ballast use and qualified to AEC‑Q200, the UCYW6120MPD combines high ripple capability, long operational life, and a wide operating temperature range (−40 °C to 105 °C) to support demanding, long‑life applications including automotive electronic systems.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance with a 420 V rated voltage and ±20% capacitance tolerance at 20 °C, 120 Hz.
• High Ripple Current — Low‑frequency ripple current of 150 mA (120 Hz) and high‑frequency ripple current of 300 mA (100 kHz) for robust performance under load.
• Long Endurance — Rated for 10,000 hours at 105 °C, providing extended service life in high‑temperature environments.
• Thermal Range — Operates from −40 °C to 105 °C to cover a wide set of environmental conditions.
• Electrical Losses — Tangent of loss angle (tan δ) of 0.24 measured at 20 °C, 120 Hz, for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 301.6 µA for predictable stand‑by behavior after voltage application.
• Compact Radial Can — φ10 mm diameter × 20 mm length aluminum can with 5.0 mm lead spacing (±0.5 mm) in radial lead format for through‑hole assemblies.
• Compliance & Qualification — RoHS compliant and AEC‑Q200 qualified to support reliability‑focused designs.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit assembly and stocking preferences.

Typical Applications

• Power Supplies — Energy storage and smoothing in PCB power rails where high DC voltage and ripple endurance are required.
• Ballasts and Lighting Electronics — Capacitive filtering and ripple handling in ballast and lighting power circuits.
• Automotive Electronic Systems — Supporting high‑voltage, high‑temperature automotive electronics thanks to AEC‑Q200 qualification and a −40 °C to 105 °C operating range.

Unique Advantages

• High ripple capability: Specified ripple currents of 150 mA (120 Hz) and 300 mA (100 kHz) reduce stress on upstream regulation and improve power stability.
• Long operational life: 10,000 hours at 105 °C enables extended maintenance intervals and reliable long‑term operation in high‑temperature applications.
• Compact footprint: φ10 × 20 mm can and 5.0 mm lead spacing deliver high voltage handling in a small through‑hole form factor for space‑constrained designs.
• Automotive‑grade qualification: AEC‑Q200 qualification supports use in designs that require industry standard stress testing for passive components.
• Predictable electrical behavior: Defined tan δ (0.24 at 20 °C, 120 Hz) and specified leakage current (301.6 µA) simplify thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS compliance for environmental and supply‑chain requirements.
