UKA0J223MHD

The UKA0J223MHD is a Nichicon UKA-series aluminum electrolytic capacitor engineered for high‑grade audio equipment and other precision audio power systems. It is a polarized, radial‑lead can-type capacitor offering very large capacitance in a compact φ18×40 mm package with 7.5 mm lead spacing.

Designed for wide operating temperatures (−55°C to +105°C) and extended endurance, this part provides bulk energy storage and ripple handling for audio power rails where long life and stable performance under thermal stress are required.

Key Features

• High Capacitance, Low Voltage — 22 mF (22,000 µF) rated at 6.3 V for large bulk energy storage in low‑voltage audio supply rails.
• Wide Temperature Range — Operates from −55°C to +105°C to support demanding environmental conditions common in professional and consumer audio equipment.
• Endurance at Elevated Temperature — 2000 hours at 105°C rating for extended life under high‑temperature operation.
• Ripple Current Capability — Rated ripple current of 2.35 A (mArms) at 105°C / 120 Hz and 2.703 A at 100 kHz for effective smoothing of power supply ripple across audio frequency and switching environments.
• Loss Tangent (tan δ) — Specified tan δ of 0.72 consistent with the large capacitance value, useful for assessing AC loss in audio power applications.
• Leakage Current — Measured leakage of 4,158 µA after 1 minute and 1,386 µA after 2 minutes at 20°C; series guidance: leakage not more than 0.03CV after 1 minute and 0.01CV after 2 minutes (20°C).
• Package & Mounting — Radial lead, can style (φ18×40 mm) with 7.5 mm lead spacing for through‑hole mounting and robust mechanical retention.
• AEC‑Q200 Rating — Series includes AEC‑Q200 qualification, supporting designs that require recognized component stress test standards.

Typical Applications

• High‑Grade Audio Amplifiers — Bulk energy storage and ripple smoothing on low‑voltage amplifier rails to preserve audio fidelity and reduce power supply noise.
• Audio Power Supplies — Filtering and reservoir functions in linear or switching power supplies used in professional and consumer audio equipment.
• Preamp and Signal Chain Support — Local decoupling and energy buffering where large capacitance at low voltage is needed to maintain stable bias and low hum.

Unique Advantages

• Large Bulk Storage in a Compact Can — 22,000 µF in a φ18×40 mm package minimizes board area while providing substantial energy capacity for audio rails.
• Designed for Thermal Durability — 2000‑hour endurance at 105°C and wide operating range help maintain performance in heat‑exposed enclosures.
• Frequency‑Versatile Ripple Handling — Rated ripple specified at both low (120 Hz) and high (100 kHz) frequencies to support smoothing across different power conversion topologies.
• Measurable Leakage and Loss Characteristics — Provided leakage current figures and tan δ enable predictable behavior and easier margining in sensitive audio circuits.
• Robust Through‑Hole Mounting — Radial lead can construction simplifies assembly and provides reliable mechanical strength for serviceable audio platforms.
• Qualified Stress Screening — Inclusion in an AEC‑Q200 rated series supports deployment where recognized component qualification is desired.
