UCS2C101MHD

The UCS2C101MHD is a miniature aluminum electrolytic capacitor from Nichicon's UCS series. It is a radial-lead, polarized can-type capacitor designed for general-purpose power electronics where high ripple handling and long-term reliability are required.

Targeted for power supply and ballast applications, the part delivers high ripple current capability and a long rated life at elevated temperature, providing stable smoothing and filtering in demanding operating environments.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance at 160 V DC, with a tolerance of ±20% (–20% to +20%).
• High ripple-current capability — Rated ripple current of 710 mA at 120 Hz and 1.42 A at 100 kHz for effective AC filtering and smoothing in high-frequency and low-frequency applications.
• Long-life, high-temperature endurance — Specified lifetime of 10,000 hours at 105°C under DC bias plus rated ripple current, demonstrating high reliability in elevated-temperature deployments.
• Wide operating temperature range — Operates from –40°C to +105°C to accommodate varied environmental conditions.
• Low leakage and loss characteristics — Leakage current defined by I ≤ 0.04CV + 100 µA after 1 minute at 20°C; tan δ max 0.20 at 160 V (measured at 120 Hz, 20°C), enabling predictable performance in DC filter circuits.
• Compact radial-can package — Radial lead, can-style package with 5 mm lead spacing and dimensions L: 25 mm × D: 12.5 mm (2.5 × 1.25 cm), suitable for dense board layouts requiring through-hole mounting.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk smoothing and output filtering where high ripple current handling and stable capacitance over temperature are required.
• Ballast circuits — Filtering and energy storage in lighting ballast designs that demand reliable operation at elevated temperatures.
• General-purpose power electronics — Use as a through-hole filter/smoothing capacitor in power conversion, regulator, and auxiliary supply circuits.

Unique Advantages

• High ripple tolerance across frequencies — Specified ripple ratings at both low (120 Hz) and high (100 kHz) frequencies allow designers to address a wide range of switching and mains-derived ripple conditions.
• Proven high-temperature life — 10,000-hour endurance at 105°C under rated conditions supports designs that must maintain performance over extended operational periods.
• Predictable electrical behavior — Standardized leakage current formula and tan δ specification provide clear parameters for thermal and leakage budgeting in system designs.
• Compact, board-friendly form factor — Radial lead can with 5 mm lead spacing and small footprint simplifies placement in space-constrained through-hole assemblies.
• Regulatory compliance — RoHS compliance supports environmental and regulatory requirements for commercial and industrial products.
