Key Features

• Capacitance & Tolerance — 3900 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C).
• Rated Voltage — 25 V rated working voltage for mid‑rail audio applications.
• Low‑Frequency Ripple Current — 2.3 A ripple current rating at 120 Hz, supporting demanding low‑frequency smoothing and filtering tasks.
• Leakage Current & Dissipation — Specified leakage current of 740 µA and tan δ (dissipation factor) of 0.25 measured at 20 °C, 120 Hz.
• Mounting & Package — Snap‑in radial can package (φ22 × 45 mm length) for secure, upright chassis or board mounting; tray packing for handling and assembly.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C with an endurance life of 1000 hours at 85 °C under rated voltage.
• Polarized Design — Polarized electrolytic capacitor for conventional DC power and audio circuits.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High‑grade audio amplifiers — Used for power supply smoothing and energy storage where consistent performance contributes to audio fidelity.
• Audio playback and processing equipment — Supports low‑frequency filtering requirements in HD audio devices.
• Power filtering in audio electronics — Provides ripple handling and decoupling in audio power rails.

Unique Advantages

• High ripple handling: 2.3 A ripple current at 120 Hz enables reliable low‑frequency smoothing in audio power stages.
• Audio‑focused design: Part of the LKG series developed for high‑grade audio equipment, supporting sound‑quality‑focused installations.
