UEP1E222MHD

The UEP1E222MHD is a bi-polarized aluminum electrolytic capacitor in a radial-can package, designed for general-purpose electronic applications. It delivers 2.2 mF capacitance at a 25 V rating with a compact radial form factor and 7.5 mm lead spacing.

Built for wide temperature operation from −55°C to +105°C and RoHS compliance, this device targets designs that require stable capacitance, bi-polar operation and defined ripple performance across both low and high frequencies.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at 25 V for bulk energy storage and filtering in bi-polar circuits.
• Bi-Polar Construction — Bi-polarized design suited for circuits where polarity may invert during operation.
• Wide Temperature Range — Specified to operate from −55°C to +105°C to support designs exposed to broad environmental conditions.
• Endurance — Rated lifespan: 1000 hours at 105°C with polarity inversion every 250 hours as defined by the series endurance test.
• Ripple Current Performance — Specified ripple current: 1.14 A at 120 Hz and 1.311 A at 10 kHz, with frequency coefficients available from the series data for other frequencies.
• Package & Mounting — Radial lead can with 7.5 mm lead spacing and package dimensions L: 3.55 × D: 1.8 cm for through-hole PCB assembly.
• RoHS Compliant — Conforms to RoHS directives referenced in the series documentation.

Typical Applications

• General-Purpose Electronics — For circuits requiring a bi-polar aluminum electrolytic capacitor for AC-coupling, filtering or energy storage where a 25 V, 2.2 mF device is appropriate.
• Radial-Lead PCB Assemblies — Suited to through-hole designs that use radial can capacitors with 7.5 mm lead spacing.
• Wide-Temperature Systems — Use in equipment that must maintain capacitance and ripple handling from −55°C to +105°C.

Unique Advantages

• Bi-Polar Capability: Enables use in circuits with polarity inversion without relying on single-polarity constraints.
• Wide Operating Temperature: −55°C to +105°C rating preserves performance across extreme ambient conditions.
• Defined Endurance: 1000 hours at 105°C with polarity inversion intervals specified, providing a measurable longevity benchmark for thermal stress conditions.
• Frequency-Aware Ripple Ratings: Published ripple current values at 120 Hz and 10 kHz plus series frequency coefficients help predict performance across the application spectrum.
• RoHS Compliance: Materials meet RoHS directive requirements cited in the series documentation for environmental conformity.
• Compact Radial Form: Radial can package and 7.5 mm lead spacing simplify placement in through-hole PCB layouts while delivering 2.2 mF capacitance.
