UCY2C151MHD

The UCY2C151MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can from Nichicon’s UCY series. It delivers 150 µF at 160 V with a compact φ12.5 × 30.5 mm package and is designed for demanding power environments.

Targeted at power‑supply and ballast applications and qualified to AEC‑Q200, this polarized capacitor offers high ripple handling and long life for applications requiring sustained performance at elevated temperature.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance rated at 160 V DC with capacitance tolerance of ±20% (−20%~20%).
• High ripple current capability — Low‑frequency ripple current of 905 mA at 120 Hz and high‑frequency ripple capability of 1.81 A at 100 kHz to support switching and smoothing duties.
• Long endurance at elevated temperature — Rated for 12,000 hours of life at 105°C under the specified D.C. bias plus rated ripple current.
• Low‑loss characteristics — Tangent of loss angle (tan δ) max 0.20 measured at 20°C, 120 Hz for the 160 V rating.
• Leakage current — Specified leakage current of 1,060 µA (product data value).
• Mechanical and mounting — Radial‑lead can with 5.0 mm lead spacing (±0.5 mm tolerance); compact dimensions φ12.5 × 30.5 mm (D × L).
• Qualification and compliance — AEC‑Q200 qualified and RoHS compliant for use in regulated environments.
• Packaging and status — Available in bulk (no terminal forming) or bag packing; product is in mass production.
• Frequency ripple coefficient — Use frequency coefficients for ripple current scaling: 50 Hz = 0.80, 120 Hz = 1.00, 1 kHz = 1.60, 10 kHz = 1.80, 100 kHz+ = 2.00.

Typical Applications

• Power supplies — Input and output smoothing in switched‑mode and linear power supplies where compact size and high ripple capability are required.
• Ballasts and lighting circuits — Energy storage and filtering for ballast applications as noted in the product series documentation.
• Automotive electronic modules — Suitable for automotive power electronics and control modules where AEC‑Q200 qualification and high temperature endurance are required.
• Industrial power electronics — Filtering and decoupling in industrial converters and control systems that operate to +105°C and demand long life.

Unique Advantages

• High ripple tolerance: Specified ripple currents up to 1.81 A at high frequency reduce stress on the capacitor in switching applications, improving voltage stability.
• Extended operating life: 12,000‑hour endurance at 105°C supports long service intervals in thermal‑stress environments.
• Automotive‑grade qualification: AEC‑Q200 qualification provides an added level of component assurance for transportation and high‑reliability applications.
• Compact radial package: φ12.5 × 30.5 mm can and 5 mm lead spacing enable dense PCB layouts while retaining through‑hole mechanical robustness.
• Regulatory compliance: RoHS compliance supports use in regulated markets and simplifies product compliance management.
• Predictable loss behavior: tan δ ≤ 0.20 (160 V rating) at 20°C, 120 Hz helps in thermal and loss budgeting for power designs.
