UCA2C151MHD

The UCA2C151MHD is a miniature, radial-lead aluminum electrolytic capacitor rated at 160 V and 150 µF. It is designed for general-purpose power applications that require high ripple handling and extended operational life.

Key value comes from its long endurance of 12000 hours at 105°C, high rated ripple current (1.36 A at 100 kHz / 105°C), compact φ16 × 30.5 mm can, and RoHS compliance—making it suitable for power supplies, ballasts, and other power-electronics modules.

Key Features

• Electrical Rating — 150 µF capacitance at a rated voltage of 160 V with ±20% tolerance, suitable for a range of DC power applications.
• High Ripple Current — Rated ripple current 1.36 A (1360 mA) at 100 kHz and 105°C; 680 mA at 120 Hz, enabling robust smoothing and decoupling in high-frequency power circuits.
• Long Life Endurance — Load life specified at 12000 hours at 105°C, with post-test limits for capacitance change, tan δ, and leakage current defined in the endurance specification.
• Low Loss — Tangent of loss angle (tan δ) 0.15 measured at 120 Hz and 20°C for stable AC performance.
• Leakage Current — Specified leakage current of 1060 µA after 1 minute’s application of rated voltage at 20°C for predictable standby behavior.
• Compact Radial Can — φ16 × 30.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB designs.
• Operating Range & Marking — Operating temperature −25°C to +105°C; marked with white lettering on a dark brown sleeve for clear identification. RoHS compliant.
• Packaging — Supplied in bulk / bag packing (no terminal forming) for straightforward assembly handling.

Typical Applications

• Power Supplies — Bulk filtering and output smoothing in compact DC power converters where high ripple handling and long life are required.
• Ballasts and Lighting Drivers — Ripple absorption and voltage stabilization in ballast and driver circuits operating at elevated temperatures.
• General-Purpose Electronics — Decoupling and energy storage in industrial and consumer power modules that need a compact, radial-mounted electrolytic solution.

Unique Advantages

• High ripple tolerance at elevated temperature — 1.36 A rated ripple at 100 kHz and 105°C supports demanding AC/DC and switching environments.
• Extended operational life — 12000-hour endurance at 105°C reduces replacement frequency and supports longer product service intervals.
• Compact footprint — φ16 × 30.5 mm can with standard 7.5 mm lead spacing offers a space-efficient through-hole option for PCB layouts.
• Predictable electrical behavior — Specified tan δ and leakage current figures provide measurable performance for design verification and reliability planning.
• RoHS compliant — Conforms to RoHS requirements for use in assemblies that follow environmental directives.
