UCS2D271MNY9

The UCS2D271MNY9 is a miniature-sized aluminum electrolytic capacitor in a radial can package designed for high ripple current and long-life applications. As part of Nichicon's UCS series, it is intended for general-purpose power circuits and explicitly suited for power supply and ballast applications.

Key value propositions include high ripple-current capability, extended load-life endurance at elevated temperature, compact radial-lead packaging, and RoHS compliance.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with a 200 V rated voltage, suitable for medium-voltage power filtering and energy storage roles.
• High Ripple Current — Rated ripple current of 1.265 A at 120 Hz and 2.53 A at 100 kHz, enabling robust handling of AC ripple in power supply and ballast circuits.
• Long Operational Life — Endurance specified for 10,000 hours at +105°C (series endurance notes indicate 8,000 hours for certain small sizes), supporting sustained high-temperature operation.
• Wide Temperature Range — Operating temperature range from −40°C to +105°C for reliable performance across typical industrial ambient conditions.
• Radial Lead Package — Through-hole radial can with 5 mm lead spacing and a compact footprint (L: 5 × D: 1.25 cm), facilitating easy PCB mounting and replacement.
• Polarized Electrolytic — Polarized construction with ±20% capacitance tolerance at 120 Hz, 20°C, for predictable filtering and decoupling behavior.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk filtering and ripple smoothing where 200 V rating and high ripple current capability improve voltage stability in DC rails.
• Ballasts — Designed for ballast circuits that require sustained ripple handling and long operational life at elevated temperatures.
• General-Purpose Electronics — Through-hole radial mounting for replacements or designs needing robust electrolytic capacitance in a compact can package.

Unique Advantages

• Miniature form factor: Compact L: 5 × D: 1.25 cm radial can reduces PCB area while retaining high capacitance.
• High ripple capability: Specified ripple currents at 120 Hz and 100 kHz support demanding AC ripple environments without immediate degradation.
• Extended high-temperature life: 10,000-hour endurance at +105°C supports long-term reliability in thermally stressful applications.
• Through-hole ease of use: Radial leads with 5 mm spacing simplify prototyping, assembly, and field replacement.
• Clear performance limits: Polarized design with ±20% tolerance provides predictable behavior for power filtering and energy storage.
• RoHS compliant: Meets applicable RoHS directives for regulatory conformity.
