UEP1V331MHD

The UEP1V331MHD is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for general‑purpose electronic applications. It is a radial‑lead, can‑style capacitor specified at 330 µF and 35 V with a wide operating temperature range of −55 °C to +105 °C.

Designed for through‑hole assemblies, the part combines bi‑polar polarization, defined ripple current ratings, and a 1000‑hour lifetime at 105 °C to deliver stable performance in designs that require wide‑temperature operation and reliable AC polarity handling.

Key Features

• Bi‑Polar Polarization  Enables operation without polarity orientation, useful where polarity reversal may occur.
• Capacitance & Voltage  330 µF rated capacitance at 35 V with ±20% tolerance for predictable bulk and decoupling performance.
• Wide Temperature Range  Specified for −55 °C to +105 °C to support applications across a broad thermal envelope.
• Endurance  Lifetime specified as 1000 hours at 105 °C with polarity inversion every 250 hours, meeting the UEP series endurance criteria.
• Ripple Current Ratings  Rated ripple current of 350 mA at 120 Hz and 525 mA at 10 kHz to address AC and higher‑frequency stress within rated limits.
• Radial Through‑Hole Package  Radial lead, can package with 5 mm lead spacing for straightforward PCB mounting in through‑hole assemblies.
• Compact Footprint  Size dimension listed as L: 2 × D: 1.25 cm for space‑conscious designs.
• RoHS Compliant  Compliant to RoHS (2011/65/EU, (EU)2015/863), suitable for restricted‑substance environments.

Typical Applications

• General‑Purpose Electronics  Suitable for general‑purpose circuits requiring a 330 µF, 35 V bi‑polar capacitor in a radial can package.
• Wide‑Temperature Systems  Use in equipment exposed to wide ambient temperature ranges (−55 °C to +105 °C) where capacitor stability is needed.
• Through‑Hole PCB Designs  Intended for radial lead mounting with 5 mm lead spacing for conventional through‑hole assembly processes.

Unique Advantages

• Polarity Flexibility: Bi‑polar construction removes polarity constraints and simplifies designs where polarity reversal can occur.
• Wide Operating Temperature: Rated across −55 °C to +105 °C to maintain capacitance and impedance characteristics in harsh thermal conditions.
• Defined Endurance: 1000 hours at 105 °C (with polarity inversion intervals) provides a measurable life expectation for long‑term planning.
• Frequency‑Aware Ripple Ratings: Specified ripple current values at 120 Hz and 10 kHz help designers size components for AC and higher‑frequency ripple requirements.
• Through‑Hole Compatibility: Radial lead, can package with 5 mm lead spacing supports established PCB layouts and assembly flows.
• Regulatory Compliance: RoHS compliance supports use in environments requiring restricted‑substance conformance.
