Key Features

• High Capacitance, 25 V Rating — 10,000 µF nominal capacitance at a rated voltage of 25 V, suitable for bulk energy storage and smoothing in audio power supplies.
• Wide Temperature Range — Rated for operation from −55°C to 105°C, supporting designs exposed to broad thermal environments.
• Endurance — Specified for 1,000 hours at 105°C with capacitance change within ±20% and leakage within initial specified limits.
• Ripple Current Capability — Low-frequency ripple current of 2.15 A (at 120 Hz) and high-frequency ripple current of 2.4725 A (at 10 kHz), enabling reliable performance under AC ripple stress.
• Measured Loss Angle (tan δ) — tanδ of 0.36 measured at 20°C, 120 Hz, providing a defined dissipation factor for thermal and noise considerations in audio circuits.
• Leakage Current — Specified leakage current of 7,500 µA as provided in the part data.
• Package and Mounting — Radial lead can (φ20 × 40 mm) with 10 mm lead spacing and 0.5 mm lead spacing tolerance; available in bulk (no terminal forming) or bag packing.
• Environmental Compliance and Qualification — RoHS compliant and AEC-Q200 qualified.

Typical Applications

• Audio power supplies — Bulk energy storage and smoothing for amplifiers and preamplifiers in consumer and professional audio equipment.
• Audio signal systems — Power filtering and decoupling in mixers, crossovers, and audio processing units where large capacitance is required.
• General audio electronics — Used across audio equipment designs that require wide temperature operation and long endurance at elevated temperatures.

Unique Advantages

• Large bulk capacitance: 10,000 µF provides substantial energy reserve for smoothing and transient support in audio power systems.
• Wide operating temperature: −55°C to 105°C rating ensures consistent performance across demanding thermal conditions.
• Designed for endurance: 1,000 hours at 105°C delivers predictable long-term behavior for elevated-temperature applications.
• Quantified ripple performance: Specified ripple current values at 120 Hz and 10 kHz allow designers to assess thermal and lifetime impact under load.
• Radial can packaging: φ20 × 40 mm can with 10 mm lead spacing simplifies through-hole mounting and mechanical retention in chassis-mounted audio equipment.
• Standards and compliance: RoHS compliance and AEC-Q200 qualification provide documented environmental and reliability credentials.
