The part has a rated operating temperature range of −40 °C to 85 °C and an endurance rating of 2000 hours at 85 °C. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 4700 µF nominal capacitance with ±10% tolerance, providing significant bulk energy storage in a compact through-hole package.
• Rated Voltage — 10 V rating suitable for low-voltage power rails and bias circuits.
• Low Leakage Current — Specified leakage current of 94 µA, supporting stable bias and longer hold times in low-current circuits.
• High Ripple Current Capability — Ripple ratings of 1.65 A at 120 Hz and 1.8975 A at 10 kHz reduce self-heating under AC conditions and improve reliability in filtered power supplies.
• Mechanical & Mounting — Radial lead, polarized aluminum can (φ16 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB assemblies.
• Thermal & Endurance — Operates from −40 °C to 85 °C with endurance rated at 2000 hours at 85 °C, enabling predictable life performance under elevated temperature stress.
• Packaging & Compliance — Available in bulk or bag packing (no terminal forming) and RoHS compliant.

Typical Applications

• Audio equipment — Provides bulk capacitance and low leakage for power supply smoothing and decoupling in consumer and professional audio designs.
• Audio power supplies — Handles ripple currents common in audio amplifier supplies, supporting stable rail filtering.
• Audio signal systems — Used where substantial capacitance and low leakage are required to maintain bias and low-frequency response in audio circuits.

Unique Advantages

• High bulk capacitance in a compact can — 4700 µF in a φ16 × 35.5 mm package provides large energy storage while conserving PCB real estate.
• Low leakage supports stable bias — 94 µA leakage current minimizes unintended discharge, useful for circuits that rely on held voltages.
• Robust ripple performance — Rated ripple currents of 1.65 A (120 Hz) and 1.8975 A (10 kHz) reduce thermal stress during AC loading and improve longevity.
• Through-hole radial mounting — 7.5 mm lead spacing and radial leads simplify board-level installation and mechanical retention for point-of-load capacitors.
• Designed for elevated-temperature endurance — 2000 hours at 85 °C provides a measurable baseline for life expectancy under thermal stress.
• RoHS compliant packaging options — Available in bulk or bag packing to support various production workflows while meeting RoHS requirements.
