UHV1A221MED

The UHV1A221MED is a radial-lead aluminum electrolytic capacitor designed for general-purpose electronic applications. It delivers 220 µF capacitance at 10 V with low impedance at high frequencies and rated ripple performance suitable for compact power filtering and decoupling tasks.

Key electrical and mechanical attributes include a tan δ of 0.18 (10 V, 120 Hz, 20°C), low leakage current (22 µA after 2 minutes at 20°C), 225 mA ripple at 120 Hz and 450 mA ripple at 100 kHz, a temperature range of −40°C to +105°C, and a 5000-hour lifetime at 105°C. Note: this part is listed as End of Life.

Key Features

• High ripple capability — Rated ripple current of 225 mA at 120 Hz and 450 mA at 100 kHz supports effective smoothing and filtering in compact power stages.
• Low impedance at high frequency — Series characteristics emphasize reduced impedance in the high-frequency range to improve decoupling performance.
• Stable loss characteristics — Tan δ of 0.18 at 10 V (120 Hz, 20°C) provides predictable dissipation behavior for thermal and ripple calculations.
• Long-life endurance — Specified for 5000 hours at 105°C, suitable for designs requiring extended high-temperature operation within the stated lifetime.
• Compact radial can package — φ6.3 × 11 mm body with 2.5 mm lead spacing in a radial-lead can enables space-efficient through-hole mounting.
• Low leakage current — Typical leakage specified at 22 µA (after 2 minutes at 20°C) supports low-bias current designs.
• RoHS compliant — Meets RoHS requirements for lead-free environmental compliance.

Typical Applications

• General-purpose electronics — Bulk smoothing and energy storage where a 220 µF, 10 V electrolytic capacitor is required for general circuits.
• Power supply filtering — Local output filtering and ripple attenuation in small DC power supplies and regulator outputs that need compact, through-hole components.
• Decoupling in mixed-signal boards — High-frequency low-impedance behavior makes this part suitable for decoupling tasks close to regulators and converters in space-constrained layouts.

Unique Advantages

• Measured high-frequency performance — Explicit low-impedance design and frequency-dependent ripple ratings (120 Hz and 100 kHz) provide verifiable performance for high-frequency decoupling.
• Quantified ripple margins — Separate low- and high-frequency ripple current ratings (225 mA @ 120 Hz, 450 mA @ 100 kHz) let engineers size capacitors against actual ripple spectra.
• Design-friendly dimensions — Compact φ6.3 × 11 mm can and 2.5 mm lead spacing simplify placement in dense through-hole assemblies.
• Specified endurance at elevated temperature — 5000 h at 105°C rating provides a documented lifetime metric for thermal-stressed applications.
• Predictable leakage and dissipation — Leakage current and tan δ specifications enable accurate bias and thermal budgeting in power designs.
• Environmental compliance — RoHS status supports designs targeting regulated markets.
