UEP2A221MHD

The UEP2A221MHD is a bi‑polarized aluminum electrolytic capacitor in a radial‑lead can designed for general‑purpose electronic circuits. It combines a 220 µF capacitance with a 100 V rated voltage and wide operating temperature range for use where stable bipolar performance and thermal endurance are required.

Targeted at applications that demand high voltage handling, ripple tolerance and extended life at elevated temperature, this part offers defined ripple current ratings, low‑level leakage, and RoHS compliance in a compact radial package.

Key Features

• Bi‑Polarized construction — Designed as a bi‑polarized capacitor for circuits requiring non‑polar operation across its rated conditions.
• Wide temperature range — Specified to operate from −55°C to +105°C for use in temperature‑variable environments.
• High voltage rating — 100 V rated voltage suited to higher‑voltage power and signal applications.
• Capacitance and tolerance — 220 µF with ±20% tolerance at 120 Hz, 20°C.
• Leakage current — Specified leakage current of 660 µA for predictable quiescent performance.
• Ripple current capability — Rated ripple current of 510 mA (105°C / 120 Hz) and 765 mA at 10 kHz to handle AC ripple and switching loads.
• Endurance — Designed for 1000 hours at 105°C with polarity inversion conditions per the endurance test, with defined limits for capacitance change and leakage.
• Radial lead package — φ18 × 35.5 mm can with 7.5 mm lead spacing and radial lead mounting for through‑hole assembly; available in bulk/bag packing (no terminal forming).
• RoHS compliant — Conforms to RoHS requirements for reduced hazardous substances.

Typical Applications

• General purpose electronics — Suitable for circuits requiring a bi‑polarized aluminum electrolytic capacitor with 100 V rating and wide temperature capability.
• Power supply filtering — Use where smoothing and ripple handling are required, leveraging the specified ripple current ratings.
• Bipolar/AC signal circuits — Applicable where non‑polar capacitor behavior is necessary across a broad temperature range.

Unique Advantages

• Operational flexibility across temperatures — −55°C to +105°C rating reduces the need for multiple capacitor families across the same design.
• High voltage headroom — 100 V rating enables deployment in higher‑voltage circuits without additional derating.
• Defined ripple performance — Clear ripple current specifications at 120 Hz and 10 kHz allow straightforward thermal and ripple budgeting.
• Documented endurance — 1000 hours at 105°C endurance test data with specified limits for capacitance change and leakage current supports long‑term reliability planning.
• Through‑hole radial format — φ18 × 35.5 mm can and 7.5 mm lead spacing simplify manual assembly and retrofit designs; bulk/bag packing supports high‑volume handling.
• RoHS compliance — Meets environmental requirements for regulated markets.
