• Audio-Oriented Loss Characteristics Tangent of loss angle (tan δ) specified at 0.24, reflecting the capacitor’s ESR-related behavior relevant to audio performance.
• Defined Leakage Current Leakage current specified as 3525 µA after 1 minute and 1175 µA after 2 minutes at 20°C (per 0.03CV / 0.01CV rules), providing predictable bias characteristics for design margining.
• Wide Temperature Range & Endurance Operating range −55°C to +105°C with an endurance rating of 2000 hours at 105°C, supporting long-term stability in thermally challenging equipment.
• Mechanicals & Mounting Compact radial can: φ16 × 30.5 mm case, 7.5 mm lead spacing, 0.6 mm lead diameter; supplied in bulk with no terminal forming for standard through-hole assembly.
• Component-Level Qualification AEC-Q200 listed in the specifications, indicating component stress-test qualification for demanding applications where such ratings are required.

Typical Applications

• High‑grade audio equipment — Bulk smoothing and energy storage for amplifier and preamplifier power supplies where low-noise supply rails are important.
• Audio power rails — Filtering and ripple reduction on supply lines for improved dynamic response in audio signal chains.
• Studio and professional gear — Use in mixers, signal processors, and other equipment requiring robust capacitive decoupling over a wide temperature range.

Unique Advantages

• Large-capacitance solution: 4700 µF provides substantial bulk energy storage to stabilize voltage rails and support transient currents in audio systems.
• Wide operating temperature: −55°C to +105°C rating allows deployment in varied environmental conditions while maintaining performance.
• High ripple capability: Rated ripple currents at both low and high frequencies (1.71 A @120 Hz, 1.966 A @10 kHz) support effective dissipation of AC components on supply rails.
• Predictable leakage behavior: Leakage current values defined by 0.03CV and 0.01CV limits (3525 µA / 1175 µA) help designers account for bias currents in precision audio circuits.
• Long endurance: 2000 hours at 105°C provides measurable lifetime performance for product reliability planning.
• Radial, through‑hole packaging: Standard radial can and lead spacing simplify integration into legacy and serviceable PCB designs.
