LKS1K122MESZ

The LKS1K122MESZ is a snap-in aluminum electrolytic capacitor from Nichicon's LKS series designed for audio equipment and general-purpose power filtering. It offers a compact, smaller-sized can with a snap-in mounting suitable for board-level installation where space and reliable mechanical retention are important.

Key value comes from its combination of 1.2 mF capacitance at an 80 V rating, a broad operating temperature range, and a product design aimed at improving tone quality when replacing smaller standard parts in audio applications. The device is RoHS compliant.

Key Features

• Core electrical — 1.2 mF capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in power rails.
• Package & mounting — Radial can with snap-in terminals for secure PCB installation in compact assemblies; physical size L: 2.5 cm × D: 2.2 cm supports smaller designs.
• Audio-focused design — Specified as a snap-in terminal type for audio equipment and noted for a tone-quality improvement when used as a replacement for small standard products.
• Temperature & lifetime — Rated to operate from −40°C to +85°C with an endurance rating of 1000 hours at 85°C, enabling predictable performance over the specified life interval.
• Ripple & leakage — Low-frequency ripple current rated at 1.7 A (120 Hz); leakage current meets the datasheet limit (not more than 3√CV μA after 5 minutes at 20°C), providing measured and specified electrical behavior.
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio equipment — Used for power supply smoothing and bulk decoupling in audio amplifiers and other audio electronics where replacement of smaller standard capacitors can affect tone quality.
• General-purpose power filtering — Bulk energy storage and ripple suppression on DC rails for a wide range of consumer and professional electronics.
• Compact board-level designs — Where a snap-in radial can and smaller footprint are required to save space while maintaining electrolytic capacitance.

Unique Advantages

• Compact snap-in form — Smaller-sized radial can with snap-in terminals delivers secure mechanical retention and a reduced board footprint.
• Designed for audio replacement — Specifically intended for audio equipment and promoted as delivering tone-quality improvements when upgrading from small standard parts.
• High voltage capability — 80 V rating provides headroom for higher-voltage audio and power applications without changing capacitor topology.
• Specified ripple handling — 1.7 A ripple current (120 Hz) is specified for predictable filtering performance at mains-related frequencies.
• Durability under temperature stress — Rated for −40°C to +85°C operation and 1000 hours endurance at 85°C, supporting robust performance across typical operating conditions.
• RoHS compliant — Meets current RoHS requirements for chemical content, simplifying environmental compliance for finished products.
