LKS2A222MESC

The LKS2A222MESC is an aluminum electrolytic capacitor in Nichicon’s LKS series featuring a snap-in terminal package optimized for audio equipment and general-purpose power applications. It combines a compact, smaller-sized radial can with polarized construction and a 100 V rating to support DC filtering and energy storage in space-constrained designs.

Designed to deliver audible tone-quality improvement when replacing smaller standard parts, the LKS2A222MESC is RoHS compliant and specified for operation from −40 °C to +85 °C with a rated lifetime of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance with a 100 V DC rating and ±20% tolerance, suitable for bulk energy storage and DC filtering in power and audio circuits.
• Package & Mounting — Snap-in terminal radial can (can - snap-in) for secure PCB retention and straightforward assembly into power supply and amplifier boards.
• Temperature Range — Specified operation from −40 °C to +85 °C, allowing use across a wide range of ambient conditions typical for consumer and professional audio equipment.
• Endurance — Rated lifetime of 1000 hours at 85 °C, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Ripple Handling — Low-frequency ripple current rating of 2.95 A at 120 Hz, supporting smoothing and decoupling duties in low-frequency power applications.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), meeting current restricted-substance requirements.

Typical Applications

• Audio Equipment — Use in preamplifiers, power amplifiers, and audio power supplies where replacing smaller standard capacitors can improve audible tone quality.
• Power Supply Filtering — Bulk smoothing and energy storage for DC rails in general-purpose power supplies and converters.
• Consumer & Pro Audio Electronics — Compact, snap-in form factor for space-constrained chassis and board layouts in consumer and professional audio products.

Unique Advantages

• Tone-quality improvement: Explicitly designed as a smaller-sized LKS series part intended to improve tone quality when replacing small standard capacitors in audio paths.
• High-voltage capability: 100 V rated voltage enables use on higher-voltage DC rails compared with lower-voltage electrolytic options.
• Secure snap-in mounting: Snap-in terminals provide reliable mechanical retention for through-hole PCB installation without additional hardware.
• Compact dimensions: Small radial can size (L: 2.5 × D: 3.5 cm) helps save board and chassis space in constrained designs.
• Defined reliability: 1000-hour endurance at 85 °C with specified limits for capacitance, tan δ, and leakage current supports predictable long-term behavior.
• Regulatory compliance: RoHS compliance supports design and procurement for regions requiring restricted-substance conformance.
