• Operating environment: Temperature range from −40°C to +85°C to support a broad range of audio equipment operating conditions.
• Mechanical and mounting: Snap‑in terminal, radial can package (φ20 × 50 mm length; L: 5 × D: 2 cm; max seated height 1.969 inch) supplied in tray packing.
• Regulatory: RoHS compliant.
• Marking: Printed with gold color letters on a black sleeve per series marking convention.

Typical Applications

• High‑fidelity amplifiers: Bulk filtering and power reservoir for audio amplifier power rails where audio‑grade capacitors are required.
• Professional audio gear: Power supply smoothing and decoupling in mixing consoles, studio amplifiers, and other pro audio systems.
• High‑end consumer audio equipment: Use in AV receivers, integrated amplifiers, and other consumer devices that prioritize tonal quality and stable filtering.

Unique Advantages

• Audio‑grade series design: LKG series TYPE‑III grade with gold‑plated terminal adoption targets high tone quality for HD audio equipment.
• High capacitance at low voltage: 3900 µF at 16 V provides substantial energy storage for rail stabilization in audio power supplies.
• Measured dissipation detail: Specified tanδ value (0.25 at 20°C, 120 Hz) gives a defined loss characteristic for designers balancing performance and sound quality.
• Robust ripple handling: 2.3 A low‑frequency ripple current rating (120 Hz) supports demanding AC ripple conditions typical in audio power stages.
• Durability under stress: Endurance specified to 1000 hours at 85°C—capacitor behavior after endurances is specified for capacitance, tanδ, and leakage.
• Wide temperature range: −40°C to +85°C operating range accommodates a range of audio equipment environmental conditions.
