UEP1A220MDD

The UEP1A220MDD is a bi‑polarized aluminum electrolytic capacitor designed for general‑purpose electronic circuits. It provides 22 µF capacitance at a 10 V rated voltage in a compact radial can package with radial leads and 2 mm lead spacing.

Engineered for extended temperature operation from −55 °C to +105 °C and RoHS compliance, this part targets through‑hole designs that require a compact, polarity‑agnostic capacitor with defined ripple and endurance characteristics.

Key Features

• Capacitance & Rated Voltage — 22 µF capacitance with a 10 V rated voltage and tolerance of ±20% at 120 Hz, 20 °C.
• Bi‑Polar Polarization — Bi‑polar construction allows operation with polarity inversion, as specified for the UEP series.
• Wide Operating Temperature — Specified for −55 °C to +105 °C to support circuits exposed to wide temperature ranges.
• Endurance at High Temperature — Rated for 1000 hours at 105 °C with polarity inversion every 250 hours as per series endurance specifications.
• Radial Lead Package — Radial, can style package with radial leads and 2 mm lead spacing for through‑hole mounting and straightforward PCB placement.
• Ripple Current Characteristics — Rated ripple current of 42 mA at 120 Hz and 84 mA at 10 kHz for the specified capacitance and package size.
• Low Leakage Specification — Series leakage current specified as not more than 0.03CV (µA) after 5 minutesʼ application of rated voltage at 20 °C.
• Compliance — RoHS compliant.
• Compact Dimensions — Body dimensions L: 1.1 cm × D: 0.5 cm with a seated height maximum of 1.1 cm for space‑constrained board layouts.

Typical Applications

• General‑Purpose Electronics — Use in through‑hole circuits where a bi‑polarized capacitor is required for AC or polarity‑variable signals.
• Boards Requiring Wide Temperature Operation — Suitable for equipment and modules that must perform across −55 °C to +105 °C.
• Radial Lead Through‑Hole Designs — Fits legacy and repairable PCB assemblies that favor radial can capacitors with 2 mm lead spacing.

Unique Advantages

• Polarity‑agnostic Operation: Bi‑polar construction supports applications where polarity may invert without requiring separate polarity management.
• Wide Temperature Range: Specified performance from −55 °C to +105 °C helps maintain capacitance and impedance stability across harsh environments.
• Defined High‑Temperature Endurance: 1000 hours at 105 °C (with polarity inversion schedule) provides a measurable reliability baseline for design validation.
• Compact, Through‑Hole Friendly Package: Radial can with 2 mm lead spacing and small footprint simplifies integration into existing through‑hole layouts.
• Measured Ripple Performance: Published ripple current values at 120 Hz and 10 kHz allow designers to evaluate ripple handling for specific frequency domains.
• RoHS Compliant: Meets RoHS directive requirements for material composition and environmental compliance.
