Key Features

• High Capacitance — 22,000 µF (22 mF) nominal capacitance for bulk energy storage and smoothing on 16 V circuits.
• Rated Voltage — 16 V DC nominal rating suitable for low-voltage power rails.
• Ripple Current Capability — 3,000 mA at 120 Hz (low frequency) and 3,450 mA at 10 kHz (high frequency) to support circuits with significant AC ripple.
• Loss Tangent (tan δ) — 0.64 (DF) measured at 20°C, 120 Hz, representative of series loss characteristics at the specified capacitance and voltage.
• Leakage Current — 10,560 µA specified leakage current at rated conditions.
• Temperature & Endurance — Operating range −55°C to 105°C with 1,000 hours rated life at 105°C.
• Package & Mounting — Radial lead, aluminum can; size φ22 × 50 mm with 10 mm lead spacing; supplied bulk (no terminal forming) in bag packing.
• Polarized — Polar capacitor for correct polarity installation in DC circuits.
• Quality & Compliance — AEC-Q200 rated with RoHS compliance noted in product data.

Typical Applications

• Audio Power Supplies — Bulk filtering and reservoir capacitance for amplifiers and audio power stages where large capacitance at low voltage is required.
• DC Power Filtering — Smoothing and decoupling on 16 V rails in industrial or consumer equipment with significant ripple currents.
• Energy Storage / Hold-up — Local energy reservoir for short-term load transients in low-voltage systems.

Unique Advantages

• Substantial Bulk Storage: 22,000 µF provides significant capacitance per component, reducing the need for multiple parallel capacitors.
• High Ripple Handling: Rated ripple currents at both 120 Hz and 10 kHz help maintain performance under AC stress and switching conditions.
• Wide Temperature Range and Endurance: −55°C to 105°C operation with 1,000 hours at 105°C supports robust performance across demanding thermal environments.
• Automotive-Grade Screening: AEC-Q200 rating supports designs that require passives meeting that specification.
• RoHS Compliant: Meets stated environmental compliance requirements for restricted substances.
• Compact Radial Can: φ22 × 50 mm form factor and standard 10 mm lead spacing simplify mechanical integration into through-hole PCBs.
