LKG2A821MESZCK

The LKG2A821MESZCK is an aluminum electrolytic snap-in capacitor in Nichicon’s LKG series, specified at 820 µF and 100 V with a radial can snap-in package (22 mm diameter × 50 mm length). It is designed for audio applications with an emphasis on high-fidelity sound and meets the tone-quality requirements for HD Audio equipment.

Key electrical and mechanical attributes include a tanδ of 0.2, ±20% capacitance tolerance, polarized construction, RoHS compliance, and rated operation across −40°C to +85°C with a 1000-hour endurance at 85°C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance rated for 100 V operation, providing significant charge storage for audio-grade applications.
• Audio-grade Design (TYPE-III) — Part of the LKG series with the CK grade code (TYPE-III Super Through) aimed at the highest tone quality; the series documentation notes gold-plated terminal options for improved contact characteristics.
• Package & Mounting — Radial, can-type snap-in terminal package for secure panel or chassis installation; physical size L: 50 mm × D: 22 mm.
• Loss and Tolerance — Specified tangent of loss angle (tanδ) of 0.2 and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Temperature Range & Endurance — Rated for −40°C to +85°C; endurance characterized as 1000 hours at 85°C with post-test limits on capacitance change, tanδ and leakage current per series specifications.
• Ripple Current Capability — Rated ripple current of 3 A at 120 Hz, suitable for the AC conditions commonly encountered in audio equipment power circuits.
• Leakage & Reliability — Series leakage current specification follows the standard 3√CV (µA) limit after 5 minutes at rated voltage (C: µF, V: V), and the capacitor meets the series’ shelf-life and restoration criteria after high-temperature storage.
• Low-Temperature Stability — Impedance characteristics documented for low-temperature use: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 12 (measurement frequency 120 Hz).
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High-grade audio equipment — Used where prioritizing fidelity and tone quality is required in audio circuits.
• HD Audio systems — Suited to designs that specify components meeting high tone-quality requirements for HD Audio equipment.
• Professional audio assemblies — Employed in equipment that benefits from stable capacitance, controlled loss (tanδ), and robust ripple handling at 120 Hz.

Unique Advantages

• Designed for high-tone fidelity — Series-level design and TYPE-III grading are focused on tone quality, aligning component selection with audio performance goals.
• High voltage and capacitance in a compact can — 820 µF at 100 V in a 22 mm × 50 mm radial snap-in package enables substantial energy storage with a small footprint.
• Robust ripple handling — 3 A ripple current rating at 120 Hz supports demanding AC conditions in audio circuits.
• Documented reliability — 1000-hour endurance at 85°C and defined leakage/tanδ limits provide verifiable lifetime characteristics for design planning.
• Low-temperature performance data — Published impedance ratios for −25°C and −40°C permit predictable behavior in varied environmental conditions.
• Regulatory compliance — RoHS conformity supports use in products targeting relevant regional requirements.
