UCS2E151MHD

The UCS2E151MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCS series designed for high ripple current and long-life applications. It provides 150 µF capacitance at a 250 V rating in a compact φ18 × 25 mm can, targeting power-supply smoothing, ballast, and general-purpose industrial electronics where sustained ripple performance and durability at elevated temperature are required.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 250 V rated voltage and capacitance tolerance of ±20% (–20%~20%).
• High Ripple Current — Engineered for demanding ripple environments with 970 mA at 120 Hz (low frequency) and 1.94 A at 100 kHz (high frequency).
• Long Life & Reliability — 10,000 hours load life at 105°C, designed for continuous operation in high-temperature applications.
• Electrical Losses — Low dissipation factor: tanδ = 0.2 (measured at 20°C, 120 Hz), supporting efficient filtering and decoupling.
• Leakage Current — Specified leakage current of 1,600 µA, suitable for power smoothing where controlled leakage is acceptable.
• Package & Mounting — Radial lead, polarized aluminum can in a compact φ18×25 mm case with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Operating Environment — Wide ambient range from –40°C to +105°C; RoHS compliant.

Typical Applications

• Power Supplies — Bulk smoothing and output filtering in AC/DC and DC/DC converters where sustained ripple handling and long life are required.
• Ballasts — Filtering and energy storage in ballast circuits, leveraging the UCS series’ suitability for ballast applications.
• General-Purpose Industrial Electronics — Decoupling and smoothing in control and auxiliary circuits that need a compact, high-reliability electrolytic.

Unique Advantages

• High ripple capability: Rated ripple currents of 970 mA (120 Hz) and 1.94 A (100 kHz) enable effective filtering across low and high frequency domains.
• Proven long life: 10,000-hour endurance at 105°C supports reliable operation in elevated-temperature installations.
• Compact radial form factor: φ18×25 mm can and 7.5 mm lead spacing allow dense PCB layouts while providing robust through-hole mounting.
• Controlled electrical characteristics: Low tanδ (0.2 at 20°C, 120 Hz) and specified leakage current help designers predict performance in power circuits.
• Production-ready availability: Mass production status and RoHS compliance simplify procurement and regulatory acceptance for volume designs.
