UKT1A221MED

The UKT1A221MED is a radial‑lead aluminum electrolytic capacitor designed for audio applications. It delivers 220 µF capacitance at a 10 V rating in a compact φ6.3 × 11 mm can, optimized for through‑hole mounting and space‑constrained audio PCBs.

Engineered for stability across a wide temperature range and long‑term operation, this part offers a 1000‑hour endurance at 105°C, defined ripple‑current capability, low leakage, and AEC‑Q200 qualification for component reliability.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 10 V nominal voltage and ±20% tolerance for predictable charge storage in audio supply rails.
• Wide Temperature & Endurance — Operating range −55°C to 105°C with 1000 hours endurance at 105°C to support sustained high‑temperature operation.
• Ripple Current Performance — 175 mA at 120 Hz (low frequency) and 262.5 mA at 10 kHz (high frequency) to manage AC stress on power rails in audio circuits.
• Low Leakage & Loss — Specified leakage current of 66 µA and tangent of loss angle (tan δ) of 0.26 at 20°C, 120 Hz for controlled self‑discharge and dissipation.
• Compact Radial Package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through‑hole assembly.
• AEC‑Q200 Qualified — Rated for higher reliability; suitable where enhanced component qualification is required.
• Packaging & Status — Available in bulk/bag packing; product status: End Of Life.

Typical Applications

• Audio power supply smoothing — Bulk decoupling and smoothing on audio amplifier rails where 220 µF at 10 V supports stable supply rails.
• Coupling/decoupling in audio circuits — Use for signal path decoupling or power‑rail filtering in general audio equipment.
• Compact through‑hole designs — Small φ6.3 × 11 mm can and radial leads simplify integration into compact, serviceable PCBs for audio devices.

Unique Advantages

• Space‑efficient form factor: The φ6.3 × 11 mm can delivers 220 µF capacitance in a small footprint for space‑constrained audio PCBs.
• High‑temperature endurance: 1000 hours at 105°C provides predictable life and performance in elevated ambient conditions typical of enclosed audio equipment.
• Measured ripple handling: Specified ripple currents at both 120 Hz and 10 kHz help limit internal heating and extend service life under AC stress.
• Low leakage and controlled dissipation: 66 µA leakage and a defined tan δ support stable bias behavior and manageable ESR-related loss in signal and power paths.
• Through‑hole convenience: Radial lead construction with 2.5 mm lead spacing eases manual assembly, prototyping, and repairability.
• Qualified reliability: AEC‑Q200 rating signals component qualification appropriate for designs that require documented reliability standards.
