LKS2A222MESZ

The LKS2A222MESZ from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series, optimized for audio equipment and general-purpose electronic use. It combines a 2.2 mF capacitance with a 100 V rated voltage in a smaller-sized snap-in can designed to improve tone quality when used to replace smaller standard parts.

Key electrical and environmental characteristics include a -40°C to +85°C operating range, RoHS compliance, snap-in mounting, and a rated lifetime of 1000 hours at 85°C—making it suitable for demanding power-filtering and audio applications where reliable bulk capacitance is required.

Key Features

• Core Electrical — 2.2 mF capacitance at a 100 V rated voltage, with capacitance tolerance of ±20%.
• Ripple Performance — Rated low-frequency ripple current of 2.95 A (120 Hz), suitable for power-supply smoothing in low-frequency applications.
• Leakage and Loss Characteristics — Leakage current specified as not more than 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) is measured at 120 Hz, 20°C.
• Mechanical & Mounting — Radial, snap-in can package providing secure board mounting for through-hole assemblies; nominal size L: 5 × D: 2.2 cm.
• Temperature & Lifetime — Rated for operation from -40°C to +85°C with endurance performance verified for 1000 hours at 85°C.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Audio-Focused Design — Smaller-sized construction in the LKS family intended to deliver tone-quality improvement when replacing small standard components.

Typical Applications

• Audio Equipment — Bulk filtering and power decoupling in audio amplifiers and related circuits; designed to deliver a measurable tone-quality improvement when used as an upgrade from smaller standard capacitors.
• General-Purpose Power Filtering — Smoothing and energy storage in power-supply rails where 2.2 mF at 100 V and 2.95 A ripple handling are required.
• Replacement Upgrades — Direct replacement in applications calling for a compact, snap-in aluminum electrolytic with robust voltage and ripple specifications.

Unique Advantages

• High Capacitance at Elevated Voltage: 2.2 mF available at a 100 V rating provides substantial bulk energy storage for higher-voltage rails.
• Designed for Audio Improvements: Smaller-sized LKS construction explicitly intended to improve tone quality versus small standard parts, making it attractive for audio upgrades.
• Snap-In Package for Secure Mounting: Radial snap-in can simplifies installation and mechanical retention in through-hole assemblies.
• Verified Endurance: Endurance specified for 1000 hours at 85°C, with post-test limits defined for capacitance change, tan δ, and leakage current.
• Measured Leakage and Loss Specs: Leakage current limit of 3√CV (µA) after 5 minutes at 20°C and tan δ measured at 120 Hz provide verifiable electrical performance data.
• RoHS Compliant: Conforms to RoHS requirements (2011/65/EU, (EU)2015/863) for environmentally conscious designs.
