Key Features

• High Capacitance — 12,000 µF nominal capacitance (listed as 12 mF) suitable for bulk energy storage and smoothing in audio power supplies.
• Rated Voltage — 16 V working voltage for low‑voltage audio systems and related circuitry.
• Tolerance — Capacitance tolerance of ±20% (−20% to +20%) measured at 120 Hz, 20 °C.
• Low‑frequency Ripple Handling — Low frequency ripple current rated at 2.75 A (120 Hz), helping manage ripple in power rails used by amplifiers and audio electronics.
• Electrical Loss — Tangent of loss angle (tan δ) specified as 0.35 at 20 °C, 120 Hz for predictable AC loss characteristics in audio circuits.
• Leakage Current — Specified leakage current of 1,310 µA after voltage application, allowing designers to account for standby current and bias conditions.
• Endurance — Rated life of 1,000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Temperature Range — Operational from −40 °C to +85 °C, supporting a wide range of environmental conditions encountered in audio equipment.
• Package and Mounting — Radial, snap‑in can package (φ30 × 30L) for secure PCB mounting and mechanical stability in chassis‑mounted audio designs.
• RoHS Compliant — Meets RoHS directive requirements as indicated in the product documentation.

Typical Applications

• Professional and Consumer Audio Amplifiers — Bulk filtering and reservoir capacitance in amplifier power supplies to support stable rail voltages for high‑fidelity playback.
• Studio and Broadcast Equipment — Power smoothing and decoupling in mixers, preamplifiers, and outboard gear where consistent audio performance is required.
• High‑grade Audio Power Supplies — Energy storage and ripple attenuation in dedicated audio supply modules for better transient response and low‑noise delivery.

Unique Advantages
