UHE1A221MED

The UHE1A221MED is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UHE series, offering 220 µF capacitance at a 10 V rating in a compact φ6.3 × 11 mm can. It is specified for general‑purpose electronic designs requiring polarized bulk capacitance with measurable low‑frequency and high‑frequency ripple handling and stable performance across a wide temperature range.

Key value propositions include compact size for board‑level use, measurable low loss at 120 Hz, and rated endurance at elevated temperature for reliable operation in sustained thermal conditions.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance rated at 10 V for bulk energy storage and smoothing in low‑voltage circuits.
• Compact Radial Can: φ6.3 × 11 mm radial, can package with 2.5 mm lead spacing (±0.5 mm tolerance) for space‑constrained, through‑hole layouts.
• Electrical Loss (tan δ): tanδ = 0.19 measured at 20°C, 120 Hz, indicating defined loss characteristics useful for AC and ripple performance budgeting.
• Ripple Current Capability: Rated low‑frequency ripple current 238 mA at 120 Hz and high‑frequency ripple current 340 mA at 10 kHz, enabling effective handling of both line‑frequency and higher‑frequency ripple components.
• Leakage Current: Specified leakage current of 22 µA, measurable for bias‑dependent standby current planning.
• Operating Temperature & Endurance: Rated for −40°C to +105°C with a life/endurance of 4000 hours at 105°C for designs requiring prolonged elevated‑temperature operation.
• Capacitance Tolerance & Polarity: Capacitance tolerance −20% to +20%; polarized device for DC applications.
• RoHS Compliant & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing to suit procurement and assembly needs.
• Series Characteristics: Part of the UHE series, which is described in the series documentation as miniature sized with low impedance and high reliability.
• Status: End Of Life – note this status when planning new designs or sourcing spares.

Typical Applications

• General Purpose Electronics: Provides bulk capacitance for general‑purpose circuits that require a 220 µF, 10 V polarized electrolytic capacitor in a compact radial can.
• Board‑Level Power Modules: Compact footprint and defined ripple current ratings suit board‑mounted power filtering and local energy storage where radial through‑hole components are used.
• Industrial and Consumer Modules: Designed for sustained operation up to 105°C and specified endurance, supporting modules with steady elevated‑temperature exposure.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm can and 2.5 mm lead spacing minimize board area while providing 220 µF nominal capacitance.
• Measured loss characteristic: tanδ = 0.19 at 20°C/120 Hz gives a clear, verifiable parameter for loss budgeting and thermal design.
• Dual‑frequency ripple handling: Specified ripple current values at both 120 Hz and 10 kHz support mixed‑frequency ripple environments.
• Wide temperature range with endurance: Rated −40°C to +105°C with 4000 hours endurance at 105°C for reliable performance under elevated thermal conditions.
• RoHS compliance: Meets RoHS directive requirements for regulated substances.
• Series pedigree: Part of Nichicon’s UHE series, characterized in the series documentation for miniature size, low impedance and high reliability.

Why Choose UHE1A221MED?

UHE1A221MED delivers a compact, polarized electrolytic solution for designs that need 220 µF at 10 V with clearly specified loss, ripple current, leakage and endurance figures. Its radial can and small footprint make it suitable for board‑level placement where through‑hole mounting is preferred and space is limited.

This part is positioned for engineers and procurement teams seeking a defined, verifiable capacitor specification for general‑purpose electronic designs, with the caveat that the part is currently End Of Life—plan accordingly for sourcing or alternate selection.
