LKS1H222MESY

The LKS1H222MESY is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LKS series, sized for applications where compact, high-tone quality components are desired. It is specified at 2.2 mF (2200 µF), 50 V with polarized construction and snap-in radial can packaging, targeted primarily at audio equipment and general-purpose electronic designs.

This part offers a combination of capacitance, rated voltage, and a rated ripple capability at 120 Hz while meeting RoHS environmental requirements, making it suitable for designers seeking a smaller form-factor replacement to influence audio tone quality without changing mounting style.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) rated at 50 V with ±20% tolerance, providing energy storage capacity appropriate for audio and general-purpose circuits.
• Snap-in Mounting & Package — Snap-in terminal type in a radial can package for straightforward board or chassis installation using snap-in retention.
• Polarized Electrolytic — Polar construction suitable for DC-biased applications that require electrolytic capacitance.
• Operating Range — Specified for operation from −40°C to +85°C, supporting common commercial and professional equipment environments.
• Endurance — Rated lifetime of 1000 hours at 85°C with the rated voltage applied; after this endurance test, capacitance change is within ±20% and leakage current remains at or below the initial specified value.
• Leakage Current Specification — Leakage current after 5 minutes at 20°C does not exceed 3√(C·V) µA (C = rated capacitance in µF, V = rated voltage in V), per series specification.
• Ripple Current — Rated low-frequency ripple current of 1.75 A at 120 Hz, specified for this part.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Compact Footprint — Compact dimensioned body (approximately 3 × 2 cm), designed for smaller-sized applications within the LKS family.

Typical Applications

• Audio Equipment — Used in audio designs where replacing a smaller standard capacitor can produce a measurable effect on tone quality as noted for the LKS series.
• General-Purpose Electronic Equipment — Suitable for a variety of commercial and professional devices that require polarized electrolytic capacitance with snap-in mounting.
• Equipment Maintenance & Upgrades — As a smaller-sized replacement option for existing designs where improved tone quality or compactness is desired without changing mounting method.

Unique Advantages

• Designed for Tone Quality Improvements — The LKS series is specified as delivering higher-tone quality relative to certain standard grades, making it a targeted choice for audio designers seeking sonic refinement.
• Snap-in Robustness — Snap-in terminal construction enables secure mechanical retention and easy installation in assemblies designed for snap-in caps.
• Known Endurance Behavior — Specified 1000-hour endurance at 85°C with defined post-test limits for capacitance and leakage current, giving predictable long-term behavior under rated conditions.
• Verified Leakage Limit Formula — Leakage current defined by the 3√(C·V) formula provides a clear, measurable acceptance criterion for quality and screening.
• Rated Ripple Capability — 1.75 A at 120 Hz rating allows designers to assess AC current handling for filtering or decoupling roles within the specified frequency.
• RoHS Compliant — Conforms to RoHS directives, supporting regulatory and environmental requirements for many markets.
