UEP1J331MHD

The UEP1J331MHD is a Nichicon UEP series aluminum electrolytic capacitor configured as a bi‑polarized, radial‑lead can. It provides 330 µF capacitance at a 63 V rating with ±20% tolerance and is designed for general‑purpose electronic assemblies.

Key value comes from its wide operating temperature range (−55 °C to +105 °C), a 1000‑hour endurance rating at 105 °C, and bipolar construction—making it suitable where polarity inversion and sustained thermal performance are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, providing a stable bulk capacitance option for through‑hole designs.
• Bi‑Polarized Construction — Bi‑polar design from the UEP series enables operation with polarity inversion as covered by the endurance test procedure.
• Wide Temperature Range — Rated for −55 °C to +105 °C to support a broad set of thermal environments.
• Endurance — Specified life of 1000 hours at 105 °C with polarity inversion every 250 hours, meeting the series endurance criteria for long‑term operation.
• Ripple Current Performance — Rated ripple currents of 535 mA at 120 Hz and 802.5 mA at 10 kHz for reliable AC handling in decoupling and filtering roles.
• Radial Through‑Hole Package — Radial can with radial lead mounting and 7.5 mm lead spacing (P), suitable for standard through‑hole assembly processes.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General‑Purpose Electronics — Use as a bulk or smoothing capacitor in board‑level designs that require a 330 µF, 63 V bipolar solution.
• Wide‑Temperature Systems — Suitable for equipment that must operate across −55 °C to +105 °C thanks to the wide temperature rating.
• Through‑Hole Power Assemblies — Radial lead and can package make this capacitor appropriate for through‑hole power modules and control boards.

Unique Advantages

• Bipolar capability: Supports polarity inversion as specified by the UEP series endurance test, enabling flexible circuit topologies that may encounter changing polarities.
• Wide thermal tolerance: −55 °C to +105 °C rating helps ensure stable performance in varied ambient conditions.
• Documented endurance: 1000 hours at 105 °C (with polarity inversion every 250 hours) provides a measurable reliability baseline for design validation.
• Measured ripple handling: Rated ripple currents of 535 mA at 120 Hz and 802.5 mA at 10 kHz give clear guidance for AC and high‑frequency filtering applications.
• Through‑hole friendly package: Radial can with 7.5 mm lead spacing simplifies board layout for legacy and serviceable designs.
• Regulatory compliance: RoHS compliance supports use in regions requiring restricted‑substance adherence.
