UFW0J223MHD

The UFW0J223MHD is an aluminum electrolytic, radial-lead capacitor from Nichicon’s UFW series, specified for audio equipment. It delivers a large 22,000 µF capacitance at a 6.3 V rating in a compact φ18 × 40 mm can, providing high bulk energy storage for low-voltage audio applications.

Key value comes from its combination of very high capacitance, defined ripple-current capability at both low and high frequencies, and a rated 2,000-hour endurance at 85°C, making it suitable where sustained performance under thermal stress is required.

Key Features

• Bulk Capacitance & Rated Voltage — 22,000 µF nominal capacitance at 6.3 V with ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Rated 3,200 mA at 120 Hz (low frequency) and 3,680 mA at 10 kHz (high frequency), supporting significant AC load currents.
• Dissipation Factor — tan δ = 0.7 (DF) measured at 20°C and 120 Hz, reflecting the part's loss characteristics at the specified condition.
• Leakage Current — Specified leakage current of 4,158 µA.
• Endurance & Temperature Range — Rated for 2,000 hours at 85°C; operating temperature range −40°C to +85°C.
• Package & Mounting — Radial lead, can-style package with φ18 × 40 mm dimensions (L: 4 × D: 1.8 cm) and 7.5 mm lead spacing; supplied Bulk (No Terminal Forming) / Bag packing.
• Polarized — Polar aluminum electrolytic construction for DC bulk energy storage.
• Lifecycle Status — This part is listed as End Of Life.

Typical Applications

• Professional audio amplifiers — Provides large bulk capacitance for low-voltage audio power rails in amplifier designs.
• Consumer audio systems — Applicable where high-capacitance, through-hole components are needed for audio electronics.
• Audio power supplies — Suitable for supply filtering and energy storage in audio equipment within the specified temperature and endurance limits.

Unique Advantages

• Very high capacitance in a compact can: 22,000 µF in a φ18 × 40 mm radial can provides substantial energy storage without a large footprint.
• Designed for mixed-frequency ripple: Separate ripple-current ratings at 120 Hz and 10 kHz support both low- and high-frequency AC stress profiles.
• Rated endurance under heat: 2,000 hours at 85°C gives a defined lifecycle metric for thermal stress planning.
• Through-hole, serviceable form factor: Radial lead and bag/bulk packing simplify board-level mounting and replacement in assembled equipment.
• Clear specification set: Explicit values for tan δ, leakage current, ripple current, and operating temperature allow direct engineering comparison and reliability assessment.
