LKG1V821MESYCK

The LKG1V821MESYCK is a Nichicon LKG series aluminum electrolytic capacitor in a snap‑in (lug) radial can package, specified at 820 µF and 35 V with ±20% tolerance. It is designed for audio equipment and HD audio applications where low loss and reliable ripple handling are required.

Key electrical and reliability attributes include a specified tangent of loss angle (tan δ) of 0.22, a rated ripple current of 850 mA at 120 Hz, a leakage current figure of 500 µA, and an endurance rating of 1000 hours at 85 °C. Note: this part is listed as End of Life.

Key Features

• Package and Mounting Snap‑in radial can (φ20×25 mm), designed for secure PCB mounting and robust mechanical retention in audio equipment assemblies.
• Electrical Rating 820 µF capacitance at 35 V with ±20% tolerance, suitable for smoothing and filtering in audio power rails.
• Low Loss Performance Specified tan δ = 0.22 (measurement frequency 120 Hz, 20 °C) to support low‑loss audio signal and power filtering.
• Ripple Current Handling Rated ripple current of 850 mA at 120 Hz to manage dynamic load currents in audio amplifier and supply circuits.
• Leakage Current Product specification lists leakage current at 500 µA; the LKG series datasheet also specifies a series criterion of not more than 3√CV (µA) after 5 minutes at 20 °C.
• Thermal and Endurance Operating range −40 °C to +85 °C and endurance of 1000 hours at 85 °C (within ±20% capacitance change and leakage/tan δ limits per series specification).
• Regulatory Compliance RoHS compliant as indicated for the LKG series.

Typical Applications

• High‑fidelity audio amplifiers — Bulk and decoupling capacitance for power stages in consumer and professional audio designs.
• Audio power supplies — Smoothing and ripple suppression in linear and regulated supplies serving audio circuits.
• Studio and consumer HD audio equipment — Component selection for designs prioritizing low loss and audible performance characteristics.

Unique Advantages

• Audio‑oriented design: The LKG series is specified for audio use and HD audio equipment, aligning electrical characteristics with audio application needs.
• Low loss (tan δ = 0.22): Lower dissipation supports clearer power delivery and reduced thermal stress in audio signal paths.
• Solid ripple capability: 850 mA ripple rating at 120 Hz helps the capacitor tolerate dynamic currents typical in amplifier power rails.
• Compact snap‑in form factor: φ20×25 mm radial can with snap‑in terminals provides a compact solution with reliable board retention.
• Proven endurance specification: 1000 hours at 85 °C endurance provides a measurable reliability baseline for design validation.
• RoHS compliant: Conforms to RoHS requirements as noted for the series.
