LKSH2222MESZ

The LKSH2222MESZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, optimized for audio equipment and general-purpose electronic designs. This smaller-sized, radial can capacitor delivers 2.2 mF capacitance at a 71 V rating and is offered as a compact alternative to standard parts to help achieve audible tone-quality improvements in audio circuits.

Designed for board-level snap-in mounting, the part combines a compact package with performance attributes useful in power filtering and decoupling in audio and general-purpose applications, and is RoHS compliant.

Key Features

• Electrical Characteristics — Rated capacitance 2.2 mF with a tolerance of ±20% (−20% to 20%); rated voltage 71 V.
• Ripple Performance — Rated ripple current 2.25 A at 120 Hz, suitable for typical audio power supply filtering at mains-derived frequencies.
• Temperature Range — Operates across −40°C to +85°C, supporting a wide range of ambient conditions for consumer and general-purpose equipment.
• Endurance and Reliability — Specified endurance of 1000 hours at 85°C with limits: capacitance change within ±20%, tan δ up to 200% of the initial specified value, and leakage current not exceeding the initial specified value after endurance testing.
• Leakage Current Specification — After 5 minutes application of rated voltage at 20°C, leakage current is specified as not more than 3√(C·V) μA (where C is μF and V is volts), enabling predictable charge-loss behavior.
• Package & Mounting — Radial can with snap-in terminals for secure, board-level mounting and straightforward installation in power electronics assemblies.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Audio Equipment — Used in power supply filtering and decoupling to help improve perceived tone quality when replacing smaller standard capacitors.
• General-Purpose Power Filtering — Suitable for smoothing and energy storage in general-purpose electronic power supplies and assemblies.
• Consumer Electronics — Applied where compact, snap-in electrolytic capacitance is required for board-mounted power reservoirs and decoupling.

Unique Advantages

• Compact, audio-focused design: The LKS series is described as smaller-sized and aimed at improving tone quality when used as an upgrade from smaller standard parts.
• High-voltage capability for its class: 71 V rated voltage allows use in higher-voltage audio and general-purpose power circuits without changing topology.
• Predictable ripple handling: Rated ripple current of 2.25 A at 120 Hz gives designers a clear parameter for thermal and ripple budgeting in mains-frequency applications.
• Defined endurance profile: 1000 hours at 85°C with specified limits for capacitance, tan δ, and leakage current supports design reliability assessments and lifetime planning.
• RoHS compliance: Meets current restricted-substances requirements, simplifying regulatory acceptance for consumer and commercial products.
• Snap-in mounting: Radial can with snap-in terminals provides secure mechanical retention and straightforward assembly in through-hole board layouts.
