LKG1K222MESCCK

The LKG1K222MESCCK is a snap-in, aluminum electrolytic capacitor from Nichicon’s LKG series designed for audio applications. It delivers 2200 µF capacitance at an 80 V rating in a radial, snap-in can package tailored for high-fidelity audio equipment.

Built to the LKG series’ audio-focused construction (Type‑III, "CK" grade), this part balances large energy storage, high ripple-handling and a defined lifetime profile for use in power rails and smoothing stages of audio systems. The part is RoHS compliant and supplied in tray packaging; note this specific part is designated End of Life.

Key Features

• Electrical Capacity — 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and smoothing in audio power rails.
• High Voltage Rating — Rated for 80 V operation to support higher-voltage audio amplifier and power supply designs.
• Audio-Grade Construction (Type‑III) — Type‑III (CK) grade in the LKG series intended for highest tone quality; the series is specified “For Audio Use.”
• Ripple and Leakage — Rated ripple current of 3.9 A at 120 Hz and specified leakage current of 1250 µA, enabling continuous decoupling and smoothing under typical audio power conditions.
• Reliability & Lifetime — Endurance specification of 1000 hours at 85°C with operating temperature range −40°C to +85°C.
• Mounting & Package — Radial, snap-in (lug) terminal can package (φ35 × 40 mm length) for secure chassis or board mounting; supplied in tray packaging.
• Regulatory — RoHS compliant as stated in the product data.

Typical Applications

• High‑fidelity amplifiers — Bulk filtering and rail smoothing where high capacitance and an 80 V rating are required for clean power delivery to amplifier stages.
• Professional audio equipment — Power supply decoupling and energy buffering in studio consoles, preamplifiers and other high‑grade audio devices that specify audio‑focused components.
• Audio power supplies — Filtering and ripple reduction on higher-voltage rails to maintain stable supply under dynamic audio loads.

Unique Advantages

• Audio‑focused design — LKG series heritage and Type‑III (CK) designation target high tone quality for HD audio applications.
• High voltage capability — 80 V rating enables use in higher-voltage audio amplifier and supply topologies without compromising capacitance.
• Substantial energy storage — 2200 µF nominal capacitance supports transient load demands and bulk smoothing in audio power domains.
• Robust ripple handling — 3.9 A ripple current rating at 120 Hz supports continuous filtering duties in demanding audio power circuits.
• Proven endurance — Specified 1000 hours at 85°C for designers requiring a defined high-temperature lifetime performance.
• RoHS compliance — Meets RoHS requirements as stated in the product data.
