LKSA2472MESZ

The LKSA2472MESZ is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic assemblies. It offers a compact snap-in can package and is intended as a smaller-sized replacement part that can contribute to tone quality improvement when used in place of small standard products.

This polarized capacitor is RoHS compliant and provides key electrical and environmental characteristics useful for PCB-mounted audio and general-purpose applications, including specified ripple handling, leakage current behavior, and endurance at elevated temperature.

Key Features

• Capacitance & Voltage — Rated capacitance of 4.7 mF with a rated voltage of 42 V, suitable for a range of audio and general-purpose circuits.
• Tolerance — Capacitance tolerance of ±20% (measured at 120 Hz, 20°C), enabling predictable performance in design.
• Snap-in Radial Package — Snap-in mounting in a radial can provides robust PCB retention for assemblies and field-replaceable designs; physical size is L: 3.5 × D: 2.2 cm.
• Operating Range — Rated for operation from −40°C to +85°C, supporting typical ambient conditions for consumer and pro-audio equipment.
• Ripple and Leakage Characteristics — Rated ripple current of 2.5 A at 120 Hz; leakage current after 5 minutes at 20°C is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is rated voltage (V).
• Endurance — Designed to meet specified characteristics after 1000 hours at 85°C with rated voltage applied: capacitance change within ±20%, tan δ within 200% of initial specified value, and leakage current not exceeding initial specified value.
• Marking & Compliance — Marked with silver lettering on a black sleeve and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Intended for use in audio applications where a compact snap-in electrolytic capacitor can be used as a replacement to influence tone quality in existing designs.
• General-Purpose Electronics — Suited for a variety of general-purpose circuits that require polarized electrolytic capacitance in a snap-in package.
• PCB-Mounted Assemblies — Snap-in radial can format facilitates secure mounting on printed circuit boards for both new designs and retrofits.
• Maintenance and Upgrades — Sized for smaller installations where replacing a standard small capacitor can provide measurable changes to system behavior as noted in audio-focused use.

Unique Advantages

• Designed for audio replacement use — Marketed specifically for audio equipment and noted for tone-quality improvement when used as a replacement for smaller standard parts.
• Compact snap-in can — Radial snap-in package with compact dimensions (L: 3.5 × D: 2.2 cm) simplifies board-level installation and mechanical retention.
• Measured ripple capacity — 2.5 A ripple current rating at 120 Hz supports AC ripple handling appropriate for many audio and power-filtering roles.
• Predictable leakage behavior — Leakage current defined by the 3√CV (μA) rule after 5 minutes at 20°C gives designers a clear basis for sizing and reliability planning.
• Rated endurance — Specified 1000-hour endurance at 85°C under rated voltage with defined limits for capacitance change, tan δ, and leakage current supports lifecycle planning.
• RoHS compliant — Meets RoHS directive requirements for materials compliance.
