UVY1C221MED

The UVY1C221MED is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 16 V rating in a compact φ6.3 × 11 mm can. Built for general-purpose electronic applications, it delivers bulk energy storage and smoothing in through-hole assemblies where a small footprint and reliable performance over a wide temperature range are required.

With a rated operating range of −55°C to +105°C and endurance specified to 1000 hours at 105°C, this capacitor is targeted at designs that need predictable aging and ripple-handling characteristics across a broad set of commercial and industrial environments.

Key Features

• Capacitance & tolerance — 220 µF nominal capacitance with a tolerance of −20% to +20% for predictable bulk storage and decoupling in power circuits.
• Rated voltage — 16 V DC rating suitable for low-voltage power rails and common embedded supply voltages.
• Wide temperature range — Specified for operation from −55°C to +105°C, supporting applications across a broad ambient range.
• Endurance at elevated temperature — Rated for 1000 hours at 105°C, with capacitance and dissipation characteristics defined after the endurance test.
• Loss and measurement conditions — Tangent of loss angle (tan δ) of 0.20 measured at 20°C, 120 Hz, providing a reference for dissipation/ESR-related behavior.
• Ripple current capability — Low-frequency ripple current of 190 mA (120 Hz) and high-frequency ripple current of 285 mA (10 kHz) for effective filtering across common switching and line frequencies.
• Leakage current — Specified leakage current of 105.6 µA, enabling predictable standby and bias behavior in low-current circuits.
• Compact radial package — φ6.3 × 11 mm can with 2.5 mm lead spacing and radial lead mounting for easy insertion and robust through-hole assembly; available in bulk and bag packing.
• RoHS compliant — Meets RoHS directive requirements as indicated in the product documentation.

Typical Applications

• General-purpose power filtering — Bulk smoothing and line ripple reduction on low-voltage power rails in consumer and industrial electronics.
• Embedded and control boards — Local decoupling and energy storage for microcontroller power domains and peripheral power supplies.
• Power-supply output stages — Output filtering for linear and switching supplies where compact, through-hole capacitors are required.

Unique Advantages

• Compact, high-density storage: 220 µF in a φ6.3 × 11 mm can minimizes board space while providing useful bulk capacitance.
• Designed for wide ambient ranges: −55°C to +105°C operation supports deployment across varied environmental conditions without changing capacitor selection.
• Defined high-temperature endurance: 1000 hours at 105°C offers predictable performance retention for designs with elevated operating temperatures.
• Frequency-aware ripple handling: Separate low- and high-frequency ripple current ratings (190 mA at 120 Hz and 285 mA at 10 kHz) let engineers evaluate suitability for both mains-frequency and switching-frequency filtering.
• Measurable dissipation characteristics: tan δ specified at 20°C, 120 Hz (0.20) provides a quantifiable indicator for dissipation and thermal planning.
• Through-hole mounting and packaging options: Radial lead format with 2.5 mm lead spacing and bulk/bag packing facilitates manual assembly, automated insertion, and inventory handling.
