UCS2E330MHD

The UCS2E330MHD is a miniature aluminum electrolytic capacitor in a radial can package designed for high ripple current and extended load life. It delivers 33 µF capacitance at a 250 V rating and is intended for applications such as power supplies and ballast circuits where sustained ripple handling and long-term reliability are required.

Built for elevated-temperature operation, this polarized capacitor withstands continuous use up to +105°C and is RoHS compliant, making it suitable for general-purpose power filtering and energy-storage roles in industrial and commercial electronics.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance at 250 VDC, suitable for medium-voltage filtering and energy-storage tasks.
• High Ripple Current — Rated ripple performance of 400 mA at 120 Hz and 800 mA at 100 kHz, enabling robust AC ripple handling in power circuits.
• Long Life at Elevated Temperature — Designed for 10000 hours of load life at +105°C, providing extended service life under high-temperature stress.
• Temperature Range — Operating range from –40°C to +105°C for broad environmental tolerance.
• Dissipation Factor (tan δ) — tan δ maximum of 0.20 at 120 Hz and 20°C for the 250 V rating, aiding assessment of losses in AC conditions.
• Low-Temperature Stability — Impedance ratios of Z(–25°C)/Z(+20°C) = 3 and Z(–40°C)/Z(+20°C) = 6 at 250 V, useful when designing for cold-start or low-temperature operation.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing for through-hole PCB mounting and straightforward assembly.
• Tolerance & Polarity — Capacitance tolerance ±20% and polarized construction; observe polarity during installation.
• RoHS Compliant — Meets 2011/65/EU and (EU)2015/863 directives for restricted substances.

Typical Applications

• Power Supplies — Bulk filtering and ripple smoothing where high ripple current capability and long life at elevated temperature improve regulator stability and longevity.
• Ballasts & Lighting Controls — AC ripple management in ballast circuits where sustained ripple tolerance and thermal endurance are important.
• General-Purpose Industrial Electronics — Energy storage and decoupling in control and power-distribution modules that operate across –40°C to +105°C.

Unique Advantages

• High Ripple Handling: Measured ripple ratings at both low and high frequencies (400 mA at 120 Hz, 800 mA at 100 kHz) allow designers to specify a single part for diverse ripple profiles.
• Extended High-Temperature Endurance: 10000-hour life at +105°C supports designs expected to run continuously or in thermally demanding environments.
• Compact Radial Form Factor: Radial lead can and 5 mm lead spacing provide a compact, through-hole solution that’s easy to place and solder on PCBs.
• Predictable AC Losses: A defined tan δ (0.20 at 120 Hz, 20°C) helps quantify dielectric losses for thermal and efficiency calculations.
• Wide Operating Range: –40°C to +105°C rating ensures functionality across common industrial temperature conditions.
• RoHS Compliance: Conforms to current restricted-substance directives for easier regulatory alignment in commercial products.
