LKS1J222MESB

The LKS1J222MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series designed for audio equipment and general-purpose electronic use. As a smaller-sized snap-in can, it offers high bulk capacitance in a compact package intended to improve tone quality when replacing smaller standard parts.

Key electrical and reliability attributes include a rated capacitance of 2.2 mF at 63 V, snap-in mounting for secure chassis/board installation, RoHS compliance, and endurance characterized at elevated temperature for predictable long-term behavior.

Key Features

• Capacitance & Voltage: 2.2 mF rated capacitance at 63 V for substantial bulk energy storage in audio and general-purpose circuits.
• Polarized Electrolytic Construction: Polarized aluminum electrolytic design for high capacitance-per-volume where polarity is observed.
• Tolerance: ±20% capacitance tolerance (−20% to +20%), specified at 120 Hz, 20°C.
• Ripple Current: Rated ripple current of 2 A at 120 Hz, suitable for filtering and smoothing tasks in low-frequency power paths.
• Operating Temperature: Specified operating range from −40°C to +85°C, suitable for a broad set of electronics environments.
• Endurance: 1000 hours at 85°C with rated voltage applied; after recovery to 20°C, capacitance change is within ±20%, tan δ ≤ 200% of initial specified value, and leakage current does not exceed initial specified value.
• Leakage Current Specification: After 5 minutes' application of rated voltage at 20°C, leakage current is not more than 3√(C·V) μA (C = rated capacitance in μF, V = voltage in V).
• Package & Mounting: Radial can with snap-in terminals for secure mechanical retention and straightforward board/chassis integration; physical size L: 2 × D: 3 cm and maximum seated height 2 cm.
• Environmental Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment: Bulk storage and smoothing in audio amplifiers and power supplies where replacing a smaller standard capacitor can yield tone-quality improvement.
• General-Purpose Electronics: Filtering and decoupling in equipment that requires polarized bulk capacitance and snap-in mounting for robust installation.
• Power Supply Smoothing: Low-frequency ripple filtering where the 2 A ripple rating at 120 Hz and elevated-temperature endurance are relevant.

Unique Advantages

• Tonal improvement focus: Marketed specifically for audio applications with a smaller-sized construction aimed at improving tone quality when used as an upgrade from smaller standard parts.
• Compact bulk capacitance: 2.2 mF in a 2 × 3 cm footprint delivers substantial capacitance without a large chassis impact.
• Snap-in retention: Snap-in terminal design simplifies mechanical assembly and provides stable mounting compared with loose-leaded alternatives.
• Predictable endurance: Rated for 1000 hours at 85°C under applied voltage with defined limits on capacitance change, tan δ, and leakage current for reliable long-term performance.
• Clear leakage limit: Leakage current bounded by 3√(C·V) μA after 5 minutes at 20°C offers a measurable acceptance criterion for quality verification.
• RoHS compliant: Conforms to current RoHS requirements for designs requiring restricted substance compliance.
