LKG1J681MESZCK

The LKG1J681MESZCK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKG series, specified at 680 µF and 63 V with ±20% tolerance. It is part of the LKG family designed for audio equipment, prioritizing high‑fidelity sound and stable performance in audio power systems.

Engineered for audio applications, this TYPE‑III (Super Through) grade unit features gold‑plated terminal design and is supplied in tray packing. Key electrical characteristics include low loss (tan δ 0.22), a rated ripple current of 1.75 A (120 Hz), and a 1000‑hour endurance at 85 °C.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a 63 V rated voltage, suitable where higher DC bus voltages are required in audio modules.
• Tolerance & Polarization — ±20% tolerance and polarized construction consistent with typical electrolytic capacitor usage.
• Low Loss — Specified tangent of loss angle (tan δ) of 0.22 (measured at 120 Hz, 20 °C), supporting efficient energy transfer in low‑frequency audio circuits.
• Ripple Current Capability — Rated ripple current 1.75 A at 120 Hz, enabling handling of audio power supply ripple and dynamic loads.
• Leakage Current — Rated leakage current value shown at 620 µA, providing predictable quiescent behavior after voltage application.
• Endurance — 1000 hours at 85 °C with capacitance and loss angle remaining within specified limits after recovery to 20 °C.
• Mechanical & Mounting — Snap‑in radial can package for secure chassis or PCB mounting; physical size φ22 × 25 mm (L: 25 mm × D: 22 mm).
• Audio‑Focused Grade — LKG series is developed for high‑grade audio equipment; this part is TYPE‑III (Super Through) grade with gold‑plated terminal features and gold‑letter marking on a black sleeve.
• Compliance & Packing — RoHS compliant and supplied in tray packing for handling and assembly.

Typical Applications

• High‑fidelity audio equipment — Bulk capacitance and smoothing in audio power supplies and systems where audio quality is a priority.
• Professional audio systems — Energy storage and ripple handling for amplifiers and studio gear operating at elevated DC voltages.
• Audio electronics modules — General-purpose polarized filtering and reservoir functions in audio signal chains and power stages.

Unique Advantages

• High nominal capacitance at 63 V: 680 µF provides substantial energy storage for power smoothing in higher‑voltage audio circuits.
• Low loss (tan δ = 0.22): Reduced dielectric loss at 120 Hz helps maintain audio fidelity and efficient operation under load.
• Robust ripple handling: 1.75 A ripple current rating (120 Hz) supports dynamic audio power demands.
• Designed for audio: LKG series emphasis on high‑grade audio performance and TYPE‑III construction with gold‑plated terminals targets sound quality‑focused designs.
• Predictable endurance: 1000 hours at 85 °C rating provides defined lifetime expectations for thermal stress scenarios.
• RoHS compliance and tray packing: Meets environmental compliance needs and is supplied for efficient assembly handling.
