UKT0J223MHD

The UKT0J223MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series, engineered for high-capacitance bulk storage in audio and related electronics. This polarized, radial-can device combines very large capacitance with high ripple-current capability and a wide operating temperature range for robust power filtering and energy buffering.

Key value comes from its 22 000 µF capacitance at a 6.3 V rating, elevated ripple-current ratings across low and high frequency bands, and an endurance specification of 1000 hours at 105°C for demanding thermal environments.

Key Features

• High Capacitance — 22 000 µF (22 mF) provides substantial bulk energy storage for power-rail smoothing and decoupling in audio power systems.
• Rated Voltage — 6.3 V nominal rating suited for low-voltage power rails and audio supply applications.
• Ripple Current Handling — Low-frequency ripple current 2.35 A (120 Hz) and high-frequency ripple current 2.703 A (10 kHz) to support both mains-derived and switching noise environments.
• Endurance and Temperature — Qualified for operation from −55°C to 105°C with a lifetime rating of 1000 hours at 105°C.
• Loss Characteristic — tan δ (dissipation factor) specified as 0.72 at 20°C, 120 Hz, enabling engineers to assess ESR-related heating and loss tradeoffs.
• Physical & Mounting — Radial lead can package, size φ18 × 40 mm with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Polarized Design — Standard polarized electrolytic suitable for DC power filtering and bulk storage roles.
• AEC-Q200 Rating — Specified with an AEC-Q200 rating for passive-component stress characterization.

Typical Applications

• Audio Amplifiers — Bulk supply smoothing and energy reservoir for power stages and output coupling in professional and consumer audio equipment.
• Power Supply Filtering — Low-voltage rail decoupling and hold-up in DC power supplies and pre-regulator stages.
• Switch-Mode Power Supplies — Output filtering where high capacitance and frequency-dependent ripple handling reduce audible and electrical noise.

Unique Advantages

• Large Energy Storage: 22 000 µF at 6.3 V delivers significant bulk capacitance in a compact radial-can form, reducing the need for multiple smaller capacitors.
• Robust Ripple Performance: Defined ripple current ratings at both 120 Hz and 10 kHz let designers size components for both low-frequency and high-frequency ripple conditions.
• Wide Temperature Endurance: −55°C to 105°C operating range and 1000-hour endurance at 105°C support long-term stability in thermally demanding installations.
• Serviceability and Mounting: Radial leads with 7.5 mm spacing simplify through-hole assembly and replacement in field-serviceable audio equipment.
• Qualified Stress Characterization: AEC-Q200 rating provides documented passive-component stress characterization for reliability-focused designs.
• Packaging Flexibility: Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.
