UEP2A101MHD

The UEP2A101MHD from Nichicon is a bi‑polar aluminum electrolytic capacitor in a radial can package designed for general‑purpose applications. It combines a 100 µF capacitance with a 100 V rated voltage and a bi‑polar construction, enabling use where polarity reversal may occur.

Key technical attributes include a wide operating temperature range of −55 °C to +105 °C, a defined endurance of 1000 hours at 105 °C under rated voltage, and RoHS compliance — making it suitable for designs that require stable performance across temperature extremes and long‑term operation.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance (−20% to +20%).
• Bi‑Polar Construction — Bi‑polarized design suitable for applications involving polarity reversal; endurance test includes polarity inversion every 250 hours.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, supporting applications across harsh thermal environments.
• Endurance — Specified lifetime of 1000 hours at 105 °C with rated voltage applied; capacitance change and leakage limits defined in the datasheet.
• Leakage and Dissipation — Leakage current: after 5 minutes at rated voltage and 20 °C not more than 0.03 × C × V (µA); tan δ (loss tangent) for 100 V rating: 0.10 max at 120 Hz, 20 °C.
• Ripple Current Performance — Rated ripple current: 300 mA at 120 Hz and 450 mA at 10 kHz for this part; frequency coefficient data provided in the series datasheet for scaling across frequencies.
• Radial Can Package — Radial lead mounting with 7.5 mm lead spacing and compact dimensions (L: 2.5 × D: 1.6 cm); leaded can style for through‑hole assemblies.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic assemblies — Suitable for a wide range of general‑purpose circuits that require a 100 µF, 100 V bi‑polar capacitor.
• High‑voltage circuits — Applicable where a 100 V rated aluminum electrolytic capacitor is required within the stated temperature and endurance limits.
• Environments with wide temperature variation — Designed for use across −55 °C to +105 °C operating conditions.

Unique Advantages

• Bi‑polar capability: Enables use in circuits where polarity may reverse without relying on polarized-only parts.
• High voltage and moderate capacitance: 100 V rating combined with 100 µF supports applications needing significant voltage margin in a compact package.
• Wide operating temperature: −55 °C to +105 °C rating supports deployments in broad thermal environments.
• Defined endurance: 1000 hours at 105 °C under rated voltage provides a measurable reliability baseline for thermal and lifecycle planning.
• Measured ripple performance: Published ripple current values at 120 Hz and 10 kHz (300 mA / 450 mA) and frequency coefficients in the series datasheet allow designers to budget ripple handling across frequencies.
• RoHS compliant: Meets current RoHS directive requirements for restricted substances.
