LKG1K332MESAAK

The LKG1K332MESAAK from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKG series, optimized for audio equipment. It delivers 3.3 mF (3300 µF) capacitance at an 80 V rating with a ±20% tolerance and is specified for professional audio applications that prioritize tone quality.

Built to the LKG TYPE‑I (AK) grade, this Gold Tune variant targets high‑grade and HD audio systems. Key electrical and environmental attributes include a 3.25 A ripple rating at 120 Hz, low loss characteristic (tan δ = 0.25), operating temperature range of −40°C to +85°C, and an endurance rating of 1000 hours at 85°C. Note: this part is designated End Of Life.

Key Features

• Capacitance & Tolerance — 3.3 mF (3300 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling performance.
• High Voltage Rating — Rated at 80 V, supporting higher rails commonly found in advanced audio amplifier designs.
• Audio‑Optimized Grade — LKG TYPE‑I (AK) "Gold Tune" construction designed for high tone quality and use in HD audio equipment.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.25 (measurement at 120 Hz, 20°C), indicating controlled dissipation for audio fidelity.
• Ripple Current Capability — 3.25 A at 120 Hz to handle AC ripple present in power rails of audio systems.
• Leakage and Endurance — Initial leakage current indicated and an endurance specification of 1000 hours at 85°C with defined limits on capacitance change, tan δ, and leakage after endurance testing.
• Package & Mounting — Radial can with snap‑in terminals (φ25 × 50 mm body) for secure PCB mounting and mechanical stability in chassis or board assemblies.
• Temperature Range & Compliance — Operational from −40°C to +85°C and RoHS compliant.

Typical Applications

• High‑Fidelity Audio Equipment — Intended for use in high‑grade audio and HD audio systems where tone and sound quality are primary concerns.
• Professional Audio Gear — Suited to studio and professional playback systems that require stable capacitance and low dissipation at audio frequencies.
• Audio Power Supply Assemblies — Appropriate for power modules within audio electronics that need bulk capacitance and specified ripple handling at 120 Hz.

Unique Advantages

• Audio‑Focused Construction — TYPE‑I (AK) Gold Tune grade is specified for high tone quality, supporting designs that emphasize sonic fidelity.
• High Voltage Capability — 80 V rating enables use on higher audio power rails without up‑rating or parallel devices.
• Low Dissipation — tan δ = 0.25 supports reduced audible distortion from capacitor losses at audio frequencies.
• Solid Ripple Handling — 3.25 A ripple current rating at 120 Hz helps maintain stable performance under AC ripple conditions common in audio power supplies.
• Robust Environmental Range — −40°C to +85°C operating range and 1000‑hour endurance at 85°C provide predictable behavior in a variety of installation environments.
• RoHS Compliance — Conforms to RoHS requirements for environmental and regulatory considerations.
