LKS1K222MESC

The LKS1K222MESC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series designed for audio equipment and general-purpose electronic use. It pairs a high capacitance (2.2 mF) with an 80 V rated voltage in a compact, smaller-sized snap-in can package.

Engineered for designers seeking improved tone quality when upgrading from smaller standard parts, this capacitor delivers robust ripple handling and defined endurance characteristics suitable for a range of electronic assemblies operating between -40°C and 85°C.

Key Features

• Electrical Performance  2.2 mF capacitance with ±20% tolerance and an 80 V rated voltage for high-energy storage in a single component.
• Ripple Handling  Rated low-frequency ripple current of 2.45 A at 120 Hz, supporting AC ripple conditions typical in power and audio circuits.
• Mounting & Package  Snap-in terminal, radial can package for secure board attachment and straightforward assembly in through-hole layouts.
• Operating Range  Designed for operation from -40°C to +85°C with an endurance rating of 1000 hours at 85°C.
• Reliability Metrics  Leakage current after 5 minutes at 20°C ≤ 3√(C·V) μA (where C is μF and V is volts); endurance criteria include capacitance change within ±20% and tan δ within 200% of the initial specified value after endurance testing.
• Audio-Focused Design  LKS series is specified as “for audio equipment, smaller-sized,” and promoted for tone-quality improvement when used as an upgrade from smaller standard capacitors.
• Compliance  RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Dimensions  Physical size L: 2.0 cm × D: 3.5 cm with snap-in can package suitable for space-constrained layouts.

Typical Applications

• Audio Equipment  Used in audio signal and power stages where replacing a smaller capacitor can produce a measurable tone-quality improvement.
• General-Purpose Electronic Equipment  Applicable for general-purpose smoothing, decoupling and energy storage needs in electronic assemblies that accept through-hole, snap-in components.
• Upgrades and Replacements  Suited as a higher-capacitance replacement for smaller standard capacitors to enhance performance in existing designs.

Unique Advantages

• High Stored Energy: 2.2 mF at 80 V provides substantial charge capacity for applications demanding larger bulk capacitance.
• Defined Ripple Capability: Rated 2.45 A ripple current at 120 Hz to support ripple-heavy circuits while maintaining performance.
• Reliable Endurance: Specified for 1000 hours at 85°C with clear pass/fail limits for capacitance, tan δ and leakage current, aiding predictable lifetime planning.
• Snap-in Mechanical Retention: Snap-in terminals provide a secure, board-friendly mounting option for through-hole assembly processes.
• Audio-Optimized Series: Part of the LKS audio-focused lineup and recommended where tone-quality improvement is desired when upgrading from smaller units.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted-substance adherence.
