UEP1H331MHD

The UEP1H331MHD is a bi‑polarized aluminum electrolytic capacitor designed for general‑purpose electronic applications that require reliable operation across a wide temperature range. It delivers 330 µF capacitance at a 50 V rating in a compact radial can (φ16 × 25L) with 7.5 mm lead spacing.

Engineered for extended high‑temperature operation, this part supports operation from −55°C to +105°C and an endurance rating of 1000 hours at 105°C, making it suitable for designs that demand stable capacitance and controlled loss characteristics under thermal stress.

Key Features

• Bi‑Polarized construction Supports AC or polarity‑reversing conditions as specified for the UEP series, enabling use in circuits where polarity may invert.
• Wide temperature range Rated for −55°C to +105°C to maintain performance across extreme ambient conditions.
• Electrical characteristics 330 µF nominal capacitance with ±20% tolerance and a tangent of loss angle (tan δ) of 0.14 at the 50 V rating (measured at 120 Hz, 20°C).
• Leakage current Specified leakage current of 495 µA for this part.
• Ripple current capability Rated ripple current: 460 mA at 120 Hz and 690 mA at 10 kHz (frequency‑dependent coefficients apply per the series specifications).
• Endurance 1000 hours at 105°C with polarity inversion every 250 hours as defined in the series endurance specification.
• Compact radial package Radial lead, can package (φ16 × 25L) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• RoHS compliant Compliant with RoHS directives as noted in the series information.

Typical Applications

• General‑purpose electronics Use where a bi‑polarized electrolytic capacitor is required, leveraging the 50 V rating and 330 µF capacitance for board‑level energy storage.
• Power filtering and decoupling Ripple current ratings (460 mA at 120 Hz, 690 mA at 10 kHz) support smoothing and decoupling duties on power rails and intermediate bus circuits.
• High‑temperature systems Suitable for equipment operating to +105°C thanks to the series’ wide temperature specification and 1000‑hour endurance at elevated temperature.

Unique Advantages

• Bi‑polarized design for polarity reversal: Allows operation in circuits with AC content or polarity changes without concern for single‑polarity limitations.
• Extended temperature capability: −55°C to +105°C rating extends usable range for thermally demanding environments.
• High ripple tolerance across frequencies: Measured ripple current figures at 120 Hz and 10 kHz provide quantifiable margins for filtering and decoupling tasks.
• Long endurance at elevated temperature: 1000 hours at 105°C with polarity inversion intervals specified, providing defined durability metrics for design planning.
• Compact radial package: φ16 × 25L can with 7.5 mm lead spacing offers a space‑efficient, through‑hole mounting option for legacy and industrial PCBs.
• RoHS compliance: Meets RoHS requirements noted for the UEP series, supporting regulatory needs.
