UEP1V220MED

The UEP1V220MED is a bi-polarized aluminum electrolytic capacitor designed for general-purpose electronic circuits that require stable performance across a wide temperature range. As part of Nichicon's UEP series, this radial-lead, can-style capacitor combines a 35 V rating with 220 µF capacitance and a compact φ12.5 × 20 mm footprint for straightforward integration into through-hole assemblies.

Engineered for demanding thermal environments, the UEP1V220MED supports operation from -55 °C to +105 °C and is specified for 1000 hours of endurance at 105 °C, delivering reliable capacitance and leakage performance for long-term applications.

Key Features

• Electrical Rating — Rated voltage 35 V and rated capacitance 220 µF with ±20% tolerance, providing a substantial capacitance value for smoothing and decoupling in bi-polar applications.
• Bi-Polar Construction — Bi-polarized design suitable for circuits where polarity may invert during operation; endurance testing includes polarity inversion to validate performance.
• Wide Temperature Range — Operating temperature from -55 °C to +105 °C supports applications exposed to extreme or varying ambient conditions.
• Endurance and Reliability — Specified life of 1000 hours at 105 °C with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.16 (measurement at 120 Hz, 20 °C) for stable AC performance at the rated voltage.
• Leakage Current — Initial leakage current specified at 231 µA, giving a clear baseline for power budget and standby current considerations.
• Ripple Current Capability — Ripple current ratings of 51 mA at 120 Hz and 102 mA at 10 kHz support AC and switching environments where ripple handling matters.
• Package and Mounting — Radial lead, can-style package with lead spacing of 2.5 mm and nominal size φ12.5 × 20 mm for conventional through-hole assembly and manual or automated insertion.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General-Purpose Power Supply Circuits — Bulk decoupling and smoothing where a 35 V, 220 µF bipolar capacitor is required to stabilize supply rails.
• AC-Coupled or Polarity-Variable Circuits — Bi-polar construction supports circuits that experience polarity inversion during operation or testing.
• Industrial and Environmental Extremes — Suitable for equipment exposed to wide temperature ranges due to the -55 °C to +105 °C operating rating.
• Through-Hole PCB Designs — Radial-lead can package and 2.5 mm lead spacing make this capacitor easy to place in traditional PCB layouts and assemblies.

Unique Advantages

• Designed for Wide Temperature Operation: The -55 °C to +105 °C range reduces the need for multiple part variants across different environmental conditions.
• Bi-Polar Endurance Validated: Endurance specification includes polarity inversion during testing, providing quantified reliability for bi-polar applications.
• Clear, Verifiable Electrical Data: Specified tan δ, leakage current, and ripple current values allow accurate power-budgeting and AC performance assessment.
• Compact Through-Hole Form Factor: φ12.5 × 20 mm can with 2.5 mm lead spacing simplifies layout and saves board space compared with larger radial parts.
• RoHS Compliance: Meets regulatory requirements for restricted substances, simplifying compliance tracking in your BOM.
