UEP1E330MED

The UEP1E330MED is a bi-polar aluminum electrolytic capacitor from the Nichicon UEP series designed for general-purpose circuitry that requires bipolar operation across a wide temperature range. Its radial-can construction and compact footprint make it suitable for board-level power and signal applications where stable capacitance and extended temperature tolerance are required.

This part combines a 33 µF capacitance at a 25 V rating with a specified operating range from -55 °C to 105 °C and 1000 hours of endurance at 105 °C, delivering predictable performance in demanding thermal environments.

Key Features

• Bi-Polarized Construction Designed for bipolar operation and specified endurance with polarity inversion, enabling use where polarity may reverse during operation.
• Wide Temperature Range Rated for operation from -55 °C to 105 °C to support designs that experience extreme ambient conditions.
• Electrical Ratings 33 µF capacitance at a 25 V rated voltage with tolerance ±20% (–20% to +20%).
• Endurance Specification 1000 hours at 105 °C with the polarity inverted every 250 hours, per the UEP series endurance definition.
• Ripple Current Performance Specified ripple current of 56 mA at 120 Hz and 112 mA at 10 kHz, with documented frequency coefficients in the series datasheet.
• Radial Lead, Compact Package Radial lead can construction with lead spacing 2.5 mm and compact dimensions L: 1.1 × D: 0.63 cm for space-conscious layouts.
• RoHS Compliant Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose circuitry — Suitable for general-purpose electronic designs that require a bi-polar aluminum electrolytic capacitor with wide temperature capability.
• AC-coupling and polarity-variant circuits — Bi-polarized construction supports circuits where voltage polarity can reverse or alternate during operation.
• Temperature-stressed environments — Use in equipment exposed to low and high ambient temperatures thanks to the −55 °C to 105 °C operating range.

Unique Advantages

• Bi-polar capability: Enables use in AC or polarity-inverting applications without requiring additional polarity-management components.
• Wide ambient range: −55 °C to 105 °C rating provides design headroom for products deployed in harsh thermal conditions.
• Documented endurance: 1000 hours at 105 °C with polarity inversion gives a clear specification for long-term thermal reliability planning.
• Compact radial can: Small footprint (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing simplify placement in dense PCB layouts.
• Measured ripple specs: Published ripple current values at 120 Hz and 10 kHz allow designers to validate thermal and ripple handling in their power networks.
• Regulatory compliance: RoHS conformity supports environmental and production compliance requirements.
