UKT1E221MPD

The UKT1E221MPD is a radial-lead aluminum electrolytic capacitor in the UKT series, designed for general audio equipment and applications that require stable performance across a wide temperature range. This polarized capacitor delivers 220 µF at a 25 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Engineered for reliability, the part combines a 105°C endurance rating with AEC-Q200 qualification and measurable ripple-handling capability at both low and high frequencies, making it suitable for audio-focused power and decoupling roles where long-term stability matters.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing predictable charge storage for power and signal circuits.
• Temperature and Endurance — Rated operating range from -55°C to +105°C with a guaranteed lifetime of 1000 hours at 105°C, supporting extended operation in thermally demanding audio equipment.
• Loss and Leakage Characteristics — tanδ (DF) of 0.18 measured at 20°C, 120 Hz, and specified leakage current (165 µA), enabling designers to assess dissipation and standby current precisely.
• Ripple Current Performance — Low-frequency ripple current 240 mA (120 Hz) and high-frequency ripple current 360 mA (10 kHz), allowing reliable handling of both mains-related and high-frequency ripple components.
• Package and Mounting — Radial lead (can) package, φ8 × 11.5 mm size, 3.5 mm lead spacing with 0.5 mm tolerance; available in bulk or bag packing for board-level assembly and prototyping.
• Quality Qualification — AEC-Q200 qualified, addressing reliability expectations for designs requiring documented component-level qualification.

Typical Applications

• General Audio Equipment — Specified for use in general audio systems where reliability across -55°C to +105°C and long endurance are required.
• Audio Electronics with Wide Temperature Range — Suited for audio devices that operate in varied environmental conditions due to its wide operating temperature and 1000 h endurance at 105°C.

Unique Advantages

• Compact radial can — φ8 × 11.5 mm footprint and 3.5 mm lead spacing optimize board space while providing standard radial lead mounting for through-hole assembly.
• Designed for audio use — The UKT series orientation toward audio equipment ensures relevant parameter balances such as tanδ and ripple handling tailored to audio circuit needs.
• High-temperature endurance — 1000 hours at 105°C provides predictable lifetime behavior in hot operating environments and during stress testing.
• Measured ripple capability — Specified low- and high-frequency ripple currents (240 mA at 120 Hz, 360 mA at 10 kHz) help designers size capacitors for both mains and high-frequency noise scenarios.
• Qualified for reliability — AEC-Q200 qualification supports designs that require documented component reliability and supplier-grade assurance.
• Flexible packaging — Available in bulk (no terminal forming) or bag packing to suit production or prototyping workflows.

Why Choose UKT1E221MPD?
