LKS1K222MESA

The LKS1K222MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose electronic assemblies. It delivers 2.2 mF capacitance at an 80 V rating in a smaller-sized radial can with snap-in mounting, offering designers a drop-in option when replacing smaller standard parts to influence tone quality.

Key characteristics include polarized construction, RoHS compliance, and specifications intended for sustained operation up to 85°C with defined endurance and leakage limits.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance at an 80 V working voltage for higher-voltage circuits within the LKS family range.
• Snap-in Radial Can Package — Snap-in terminal type in a radial can package for secure board mounting and mechanical retention.
• Audio-focused, Smaller-sized — Specifically described for audio equipment; replacement from smaller standard products can produce a tone quality effect.
• Operating Temperature & Endurance — Rated for -40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage (capacitance change within ±20%).
• Ripple Current — Rated ripple current of 2.45 A at 120 Hz, suitable for applications with significant low-frequency ripple.
• Leakage Current Specification — Leakage current after 5 minutes at 20°C is specified no more than 3√CV (μA), where C is μF and V is volts, providing a predictable leakage behavior.
• Tolerance & Polarization — Capacitance tolerance ±20% and polarized construction for correct circuit orientation.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Marked Identification — Printed with silver color lettering on a black sleeve for clear part identification.

Typical Applications

• Audio equipment — Replacement of smaller standard capacitors to influence tone quality and provide higher capacitance and voltage margin in audio power supplies and coupling networks.
• High-ripple power stages — Smoothing and energy buffering where up to 2.45 A ripple at 120 Hz may be present, leveraging the specified ripple current capability.
• General-purpose electronic equipment — Uses that require a polarized, snap-in radial electrolytic with 2.2 mF capacitance and an 80 V rating.

Unique Advantages

• Compact audio-oriented design: Smaller-sized LKS construction intended for audio applications enables designers to replace smaller caps without increasing board footprint significantly.
• High-voltage capability: 80 V rating supports circuits that need higher DC voltage headroom compared with lower-voltage parts.
• Defined ripple handling: 2.45 A ripple current rating at 120 Hz reduces thermal stress in low-frequency power applications.
• Engineered endurance: Endurance tested at 1000 hours at 85°C with limits on capacitance change (within ±20%), tan δ, and leakage, supporting predictable long-term behavior under rated conditions.
• Predictable leakage performance: Leakage current limited by the 3√CV (μA) rule after 5 minutes at 20°C for reliable design margining.
• RoHS-compliant manufacturing: Conforms to applicable RoHS directives for environmentally compliant assembly design.
