Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 50 V for bulk energy storage and power reserve in audio circuits.
• Audio-grade design (TYPE-I, Gold Tune) — Part number suffix AK corresponds to the LKG TYPE-I (Gold Tune) grade, designed for high-grade audio equipment and fidelity-focused applications.
• Low loss at audio frequencies — Specified tangent of loss angle (tan δ) of 0.3 (measured at 120 Hz, 20 °C) to minimize dissipative loss in audio signal environments.
• High ripple handling — Rated ripple current: 2.45 A at 120 Hz, supporting ripple filtering in low-frequency power stages.
• Robust operating range — Operating temperature range from −40 °C to +85 °C with a rated endurance of 1000 hours at 85 °C.
• Mounting & package — Snap-in, radial can package for secure panel/board mounting in assemblies designed for lug/snap-in terminals.
• Compliance — RoHS compliant.
• Polarized electrolytic — Designed for polarized circuits typical in power supply and audio DC link applications.

Typical Applications

• High-grade audio amplifiers — Bulk supply smoothing and energy reserve in amplifier power rails where fidelity is a priority.
• Professional audio equipment — Used in audio consoles, studio electronics, and other gear designed for high-fidelity sound reproduction.
• Audio power supply filtering — Filtering and ripple reduction at low frequencies for stable, low-noise audio power delivery.

Unique Advantages

• Audio-focused electrical profile — The TYPE-I (Gold Tune) grade and specified tan δ target reduced losses at audio-relevant frequencies.
• Substantial energy storage at 50 V — 3900 µF provides significant bulk capacitance for power regulation and transient support in audio power rails.
• High ripple current capability — 2.45 A (120 Hz) ripple rating enables effective smoothing in low-frequency power stages.
• Designed for durability — Endurance specification of 1000 hours at 85 °C supports reliable operation in rated environments.
• Assembly-ready snap-in package — Snap-in radial can simplifies mechanical retention in suitable chassis or PCB assemblies.
• Environmental compliance — RoHS compliant for regulatory adherence in applicable markets.
