UEP1E220MED

The UEP1E220MED is a bi‑polar aluminum electrolytic capacitor designed for applications that require non‑polar operation across a wide temperature range. It provides 22 µF capacitance at 25 V in a compact radial‑lead can (φ6.3 × 11 mm) with 2.5 mm lead spacing.

Built for general‑purpose circuitry where polarity may invert and stable performance over temperature is required, the part combines low leakage, defined loss tangent, and rated endurance for reliable operation in demanding environments.

Key Features

• Bi‑Polar Construction Supports AC coupling and applications where polarity can invert; the series is specified for polarity inversion during endurance testing.
• Electrical Ratings 22 µF capacitance at 25 V with a tolerance of −20% to +20% and tan δ (DF) of 0.20 measured at 20°C, 120 Hz.
• Wide Temperature Range Rated for operation from −55°C to +105°C for designs that require broad environmental tolerance.
• Ripple and Frequency Performance Low‑frequency ripple current of 55 mA at 120 Hz and high‑frequency ripple current of 110 mA at 10 kHz, enabling effective decoupling and filtering across frequencies.
• Low Leakage Leakage current specified at 16.5 µA (0.03 C·V), providing predictable standby behavior for sensitive circuits.
• Endurance and Reliability Endurance specified as 1000 hours at 105°C with polarity inversion every 250 hours; capacitance and loss remain within published limits after the test.
• Compact Radial‑Lead Package φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) in bulk or bag packing for straightforward through‑hole assembly.
• RoHS Compliant Manufactured to meet RoHS requirements for environmentally conscious designs.

Typical Applications

• AC Coupling and Signal Conditioning — Use where polarity can reverse, such as audio coupling or bipolar signal paths that require stable capacitance over temperature.
• Decoupling in Bipolar Power Circuits — Effective for local decoupling when AC or inverted polarities may appear across the capacitor.
• Sensor and Instrumentation Front‑Ends — Low leakage and wide temperature range help maintain signal integrity in precision measurement circuits.
• General‑Purpose Industrial Electronics — Compact radial package and defined endurance make the part suitable for a variety of control and processing modules.

Unique Advantages

• Bi‑polar design for reversible polarity: Enables AC operation and circuits where polarity reverses without the constraints of polarized capacitors.
• Wide ambient capability: −55°C to +105°C rating supports deployment in varied environmental conditions.
• Predictable leakage behavior: Specified leakage of 16.5 µA (0.03 C·V) aids designers in budgeting standby currents and bias stability.
• Defined ripple performance across frequency: Rated ripple currents of 55 mA at 120 Hz and 110 mA at 10 kHz provide measurable filtering capacity for both low and high frequency disturbances.
• Proven endurance specification: 1000 hours at 105°C with polarity inversion testing gives clear reliability expectations for long‑term use.
• Compact, easy‑to‑place through‑hole form factor: φ6.3 × 11 mm radial can with 2.5 mm lead spacing simplifies prototyping and repairable assemblies.
