UEP1A470MDD

The UEP1A470MDD from Nichicon is a bi‑polarized aluminum electrolytic capacitor in the UEP series designed for wide temperature operation and general‑purpose use. This radial‑lead, can‑style capacitor provides 470 µF capacitance at a 10 V rating with a compact φ5 × 11 mm size and 2 mm lead spacing.

Engineered for stability across a broad operating range (‑55 °C to +105 °C) and endurance under elevated temperature with polarity inversion, the UEP1A470MDD is suited for designs that require bipolar operation, moderate ripple handling, and controlled leakage performance.

Key Features

• Bipolarized design Enables operation with polarity inversion and bipolar signal environments; series endurance test includes polarity inversion every 250 hours during a 1000 hour 105 °C life test.
• Electrical performance 470 µF capacitance at 10 V with ±20% tolerance (measured at 120 Hz, 20 °C) and a specified tan δ of 0.24 (measurement: 120 Hz, 20 °C).
• Ripple handling Low‑frequency ripple current specified at 54 mA (120 Hz) and high‑frequency ripple current specified at 108 mA (10 kHz), supporting decoupling and smoothing duties in compact circuits.
• Low leakage Rated leakage current shown as 14.1 µA, supporting low‑leakage requirements in DC‑coupled and bias‑sensitive circuits.
• Wide temperature and proven endurance Operating range from ‑55 °C to +105 °C and 1000 hour endurance at 105 °C (with polarity inversion schedule as per series specification).
• Compact radial package φ5 × 11 mm can with radial leads and 2 mm lead spacing for through‑hole mounting in space‑constrained designs; supplied in bulk/bag packing.
• RoHS compliant Meets RoHS requirements for environmental compliance.

Typical Applications

• General‑purpose electronics — Bulk decoupling and smoothing where bipolar operation and moderate ripple capability are required.
• Analog and audio circuits — AC coupling and bipolar signal path support with controlled leakage and stable temperature performance.
• Power supply filtering — Local filtering and ripple suppression in small form‑factor power stages thanks to specified ripple currents at low and high frequencies.
• Industrial and instrumentation — Components for circuits that must perform across ‑55 °C to +105 °C operating range and withstand extended high‑temperature endurance testing.

Unique Advantages

• Bi‑polar capability: Allows use in circuits that see polarity reversal or require symmetric AC performance, supported by the series endurance test protocol.
• Wide operating temperature: Rated from ‑55 °C to +105 °C, enabling reliable performance across harsh thermal environments.
• Measured ripple performance: Specified ripple current values at 120 Hz and 10 kHz provide clear guidance for thermal and lifetime calculations in both low‑ and high‑frequency applications.
• Compact radial form factor: φ5 × 11 mm can and 2 mm lead spacing deliver decoupling and energy storage in constrained PCB real estate.
• Documented endurance: 1000 hours at 105 °C with polarity inversion ensures predictable capacitance, tan δ and leakage behavior after high‑temperature stress.
• RoHS compliance: Meets regulatory environmental requirements for modern electronic assemblies.
