UEP1E221MPD

The UEP1E221MPD from Nichicon is a bi‑polar aluminum electrolytic capacitor designed for general‑purpose electronic applications. It provides 220 µF capacitance at a 25 V rating in a compact radial can (φ10 × 16 mm) with 5 mm lead spacing.

Key value propositions include a wide operating temperature range of −55 °C to +105 °C, a 1000‑hour endurance rating at 105 °C, RoHS compliance, and construction that supports bipolar/polarity‑reversing applications.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V for bulk energy storage and decoupling in general‑purpose circuits.
• Bi‑Polarized Construction — Bi‑polarized design suitable for circuits where polarity may reverse or where non‑polar operation is required.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C to handle demanding environmental conditions.
• Endurance — 1000 hours at 105 °C (endurance specification from the series), supporting long‑life operation in elevated temperatures.
• Loss Factor (tan δ) — tan δ max. 0.20 at 120 Hz, 20 °C (25 V rating), providing a quantifiable dissipation characteristic for AC and ripple conditions.
• Leakage Current — Specified leakage current of 165 µA, useful for budgeting standby and quiescent currents in designs.
• Rated Ripple Current — 215 mA at 120 Hz and 322.5 mA at 10 kHz frequency coefficients provided for ripple handling evaluation.
• Package & Mounting — Radial lead can, dimensions φ10 × 16 mm, lead spacing 5 mm, supplied in bulk/bag packing for through‑hole assembly.
• Regulatory — RoHS compliant.

Typical Applications

• General‑Purpose Electronics — Provides bulk capacitance and decoupling where a bipolar, wide‑temperature part is required.
• Power Conditioning — Sized for local energy storage and ripple smoothing in low‑voltage power rails up to 25 V.
• Industrial & Instrumentation — Suitable for equipment operating across a broad temperature range due to its −55 °C to +105 °C rating and 1000 h high‑temperature endurance.

Unique Advantages

• Bi‑polar capability — Supports polarity‑reversing or non‑polar applications, reducing the need for multiple capacitor types.
• Wide operational temperature — −55 °C to +105 °C rating ensures stable performance in harsh thermal environments.
• Quantified endurance — 1000‑hour life at 105 °C provides predictable long‑term behavior for thermal stress planning.
• Compact radial can — φ10 × 16 mm form factor with 5 mm lead spacing fits space‑constrained, through‑hole layouts.
• Measured electrical characteristics — Specified tan δ, leakage current, and ripple current figures allow precise design margining for AC and power applications.
• RoHS compliant — Meets environmental directive requirements for restricted substances.
