LKSA2332MESB

The LKSA2332MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and compact general-purpose applications. It is a polarized radial can capacitor with a rated capacitance of 3.3 mF and a rated voltage of 42 V.

Engineered for compact assemblies, the part offers defined ripple handling and leakage specifications, an operating range from −40°C to +85°C, and RoHS compliance (2011/65/EU, (EU)2015/863). The series is specified to provide an effect to tone quality improvement when replacing smaller standard products.

Key Features

• Capacitance & Voltage — 3.3 mF rated capacitance at 42 V for bulk filtering and energy storage in power rails.
• Snap-in Radial Can Package — Snap-in mounting (radial, can - snap-in) provides secure mechanical retention for chassis- or board-mounted assemblies.
• Audio-focused Design — Specified as “for audio equipment, smaller-sized” with an indicated effect to tone quality improvement when used as a replacement for smaller standard parts.
• Temperature and Endurance — Rated for operation from −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
• Ripple and Leakage Characteristics — Rated ripple current of 2 A at 120 Hz; leakage current specified as not more than 3√CV (μA) after 5 minutes at 20°C.
• Tolerance & Polarization — Capacitance tolerance of ±20% and polarized construction for DC coupling applications.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk filtering and supply smoothing in amplifiers and audio subsystems where the LKS series’ smaller size and specified tone-quality improvement are beneficial.
• General-Purpose Power Filtering — Decoupling and reservoir capacitance in electronic equipment requiring 3.3 mF at 42 V and defined ripple capability.
• Chassis- or Board-Mounted Assemblies — Snap-in radial can mounting suited for compact assemblies and equipment chassis installations.

Unique Advantages

• Compact snap-in form factor — Smaller-sized snap-in radial can simplifies integration into space-constrained designs.
• Designed for audible improvement — Specified to provide an effect to tone quality improvement when replacing smaller standard components, useful in audio-focused designs.
• Defined endurance performance — Endurance tested to 1000 hours at 85°C with limits on capacitance change (within ±20%), tan δ, and leakage current maintained within initial specifications.
• Predictable leakage behavior — Leakage current limit defined as ≤ 3√CV (μA) after 5 minutes at 20°C, aiding predictable power-supply performance.
• Environmental compliance — RoHS conformity supports regulatory requirements for commercial electronic products.
