This part is rated for a wide operating temperature range (–55 °C to 105 °C) and a 2000 hour endurance at 105 °C. Note: the product status is End Of Life.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of ±20% (–20%~20%).
• Audio‑Focused Series — UKA series is specified "For High Grade Audio Equipment", positioning this capacitor for audio power and signal applications where capacitance and stability matter.
• Temperature Range — Wide operating range from –55 °C to 105 °C, supporting designs that require thermal resilience.
• Endurance & Qualification — 2000 hours endurance at 105 °C; part carries an AEC‑Q200 rating for enhanced reliability characterization.
• Loss & Leakage Characteristics — tanδ (DF) of 0.22 measured at 20 °C, 120 Hz (at 16 V); leakage current specified at 105.6 µA for this part.
• Ripple Handling — Low frequency ripple current 190 mA (120 Hz) and high frequency ripple current 285 mA (10 kHz), supporting smoothing and decoupling in power rails.
• Compact Radial Package — φ6.3×11L can with 2.5 mm lead spacing (±0.5 mm) and radial lead mounting type; available in bulk or bag packing.

Typical Applications

• Audio — Designed for high‑grade audio equipment where 220 µF/16 V capacitance, wide temperature range, and reliable ripple handling support power supply smoothing and audio circuit stability.

Unique Advantages

• Designed for audio systems — Series specification explicitly targets high‑grade audio equipment, aligning electrical characteristics with audio design needs.
• Wide thermal endurance — Rated for –55 °C to 105 °C with 2000 h endurance at 105 °C, enabling robust performance in thermally demanding environments.
• Measured loss and leakage data — Provided tanδ and leakage current figures allow designers to quantify damping and standby loss for precision applications.
• High ripple capability — Defined ripple current at both low and high frequencies supports use in power supply filtering and decoupling across audio bandwidths.
• AEC‑Q200 characterization — Inclusion of AEC‑Q200 indicates additional reliability evaluation for designs requiring documented component robustness.
• Compact, serviceable radial form — Small φ6.3×11L can with standard lead spacing simplifies replacement and through‑hole assembly for legacy and repair applications.
