LKG2A821MESCCK

The LKG2A821MESCCK is a snap-in aluminum electrolytic capacitor from Nichicon's LKG series, engineered for use in high-grade audio equipment. It offers 820 µF capacitance at a 100 V rating in a radial, snap-in can designed for robust board mounting and power filtering applications.

Key electrical characteristics include a specified dissipation factor (tanδ) of 0.2 (measured at 20°C, 120 Hz, 100 V), low-frequency ripple current rating of 2.85 A (120 Hz), and rated endurance of 1000 hours at 85°C. Note: this part is designated End Of Life.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 100 V rated voltage and a capacitance tolerance of −20% to +20%.
• Audio-Grade Design — Part of the LKG family developed specifically for audio equipment; series materials and construction prioritize tone quality for high-fidelity applications.
• Dissipation Factor — tanδ specified at 0.2 under measurement conditions of 20°C and 120 Hz at 100 V, allowing assessment of loss behavior in audio power applications.
• Ripple Current Capability — Low-frequency ripple current rating of 2.85 A at 120 Hz for handling power-supply ripple in audio amplifiers and related circuits.
• Reliability & Endurance — Designed to meet endurance specifications after 1000 hours at 85°C with recovery to 20°C, per the LKG series performance criteria.
• Mechanical & Mounting — Snap-in, radial can package (φ35 × 25 mm length) for secure PCB mounting and straightforward assembly; packaged in trays for handling.
• Environmental Compliance — RoHS-compliant.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk filtering and power smoothing on high-voltage rails where audio tonal quality and stable supply decoupling are required.
• Audio Power Supplies — Energy storage and ripple attenuation in regulated and unregulated supplies for professional and consumer audio equipment.
• HD Audio Systems — Use in high-grade audio equipment designs that prioritize signal integrity and tone quality, consistent with the LKG series intent.

Unique Advantages

• High Voltage Capacity: 100 V rating enables use on higher-voltage audio rails and power supply designs without series stacking.
• Substantial Capacitance in a Snap-In Can: 820 µF in a φ35 × 25 mm package provides significant energy storage with a snap-in mounting style for reliable PCB retention.
• Audio-Focused Series Design: LKG series construction targets tone quality and audio performance, making this part suitable for high-grade audio applications.
• Measured Electrical Parameters: Specified tanδ (0.2) and ripple current (2.85 A at 120 Hz) give engineers clear, verifiable criteria for thermal and loss budgeting.
• Endurance Specified: Rated for 1000 hours at 85°C with defined post-test limits for capacitance, tanδ, and leakage, supporting reliability planning.
• RoHS Compliance: Meets RoHS directive requirements for environmental restricted substances.
