LKG1E222MESCCK

The LKG1E222MESCCK is a snap‑in, radial aluminum electrolytic capacitor in the LKG series, specified at 2200 µF (2.2 mF) and 25 V. It is designed for audio applications with emphasis on high‑tone quality and fidelity for high‑grade and HD audio equipment.

Built for board‑level snap‑in mounting, this φ35 × 20 mm can combines compact size with audio‑focused electrical characteristics, RoHS compliance, and a TYPE‑III (Super Through) grade configuration featuring gold‑plated terminals.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 25 V, with capacitance tolerance of ±20%.
• Audio‑Focused Grade — Part of the LKG series and designated TYPE‑III (CK) Super Through grade, aimed at highest tone quality; datasheet notes adoption of gold‑plated terminals for this grade.
• Package & Mounting — Radial, can style with snap‑in terminal mounting for secure board installation; physical size φ35 mm diameter × 20 mm height.
• Temperature & Endurance — Operating range −40°C to +85°C; rated lifetime/endurance of 1000 hours at 85°C with rated voltage applied.
• Low‑Frequency Ripple Capability — Ripple current specification: 1.75 A at 120 Hz (low‑frequency rating provided).
• Leakage & Stability — Leakage current specified as not more than 3√(C·V) µA after 5 minutes at 20°C; endurance criteria include capacitance change within ±20% after endurance test and specified limits on tan δ and leakage.
• Low‑Temperature Impedance — Impedance ratios versus +20°C: Z(−25°C)/Z(+20°C) ≤ 4; Z(−40°C)/Z(+20°C) ≤ 12.
• Polarized Electrolytic — Polarized design for DC‑rail and audio power applications.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with gold‑color lettering on a black sleeve for clear part identification.

Typical Applications

• High‑grade Audio Amplifiers — Suited to power and signal stages in high‑tone‑quality amplifier designs where audio fidelity is a priority.
• HD Audio Equipment — Intended to meet the tone quality requirements of HD audio systems and high‑fidelity consumer or professional audio gear.
• Audio Power Rails — Used where a polarized aluminum electrolytic capacitor is required on board for audio equipment power supply sections.

Unique Advantages

• Audio‑optimized grade (TYPE‑III Super Through): The CK suffix indicates the Super Through grade with gold‑plated terminals, specified for the highest tone quality within the LKG series.
• Compact snap‑in form factor: φ35 × 20 mm radial can with snap‑in terminals provides a space‑efficient solution for board‑level mounting in audio equipment.
• Documented endurance: 1000 hours at 85°C with rated voltage—endurance requirements and post‑test limits for capacitance, tan δ, and leakage are specified in the series datasheet.
• Measured low‑temperature behavior: Published impedance ratios at −25°C and −40°C allow designers to evaluate performance in colder environments.
• High low‑frequency ripple handling: Specified ripple current of 1.75 A at 120 Hz supports power filtering demands in audio power supplies.
• Regulatory compliance: RoHS compliant per the stated directives for environmental and materials requirements.
