UCS2W270MND9

The UCS2W270MND9 is a miniature-sized aluminum electrolytic capacitor designed for high ripple current and long-term reliability. It is a radial lead, polar capacitor rated at 27 µF and 450 V, intended for general-purpose use in high-voltage power electronics.

Optimized for power supply and ballast applications, this capacitor offers extended life at elevated temperature and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• High Voltage Rating – Rated voltage of 450 V suitable for high-voltage power rails and circuits requiring robust DC blocking or smoothing.
• Rated Capacitance and Tolerance – 27 µF capacitance with ±20% tolerance at 120 Hz, 20°C for predictable filtering behavior.
• High Ripple Current – Rated ripple current of 290 mA at 120 Hz and 580 mA at 100 kHz, supporting demanding AC superposition on DC lines.
• Frequency Coefficients for Ripple – Frequency coefficient of rated ripple current is 0.50 at 120 Hz and 1.00 at 100 kHz or more, allowing designers to account for ripple performance across frequencies.
• Long Life at Elevated Temperature – Endurance rated for 10,000 hours at +105°C (8,000 hours for specific small case sizes), supporting long-term operation in thermally demanding environments.
• Wide Operating Temperature Range – Specified for –40°C to +105°C to accommodate a broad set of ambient and operating conditions.
• Radial Lead, Can Package – Compact radial lead construction and aluminum can package for through-hole mounting and straightforward PCB integration.
• RoHS Compliant – Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Power Supplies – Bulk smoothing and ripple handling on high-voltage DC rails in power conversion and regulation circuits.
• Ballasts and Lighting Electronics – Energy storage and ripple absorption in ballast applications, matching the series’ stated suitability for ballast use.
• General Purpose High-Voltage Circuits – Filtering and decoupling in consumer and industrial equipment that require a compact, high-voltage electrolytic solution.

Unique Advantages

• High ripple capability tied to frequency – Clear ripple current ratings and frequency coefficients allow precise thermal and derating calculations for system reliability.
• Extended high-temperature endurance – Rated 10,000 hours at +105°C (with defined exceptions), providing predictable life in hot operating environments.
• Compact radial can format – Miniature size with radial leads simplifies PCB layout in space-constrained power designs.
• Wide operating temperature window – –40°C to +105°C rating supports use across diverse ambient conditions without additional thermal qualification.
• Regulatory compliance – RoHS conformity reduces material compliance work during design and procurement.
