LKSH2332MESZ

The LKSH2332MESZ from Nichicon is a snap-in terminal, polarized aluminum electrolytic capacitor in the LKS series, optimized for audio equipment and general-purpose power filtering. With a rated capacitance of 3.3 mF and a 71 V rating, it offers a compact, high-capacitance solution in a radial, can-style snap-in package.

Designed for tone-quality improvement when replacing smaller standard parts, this RoHS-compliant component pairs compact dimensions with robust ripple handling and a broad operating temperature range for reliable performance in audio and power applications.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 71 V, providing substantial energy storage for power supply smoothing and decoupling in higher-voltage audio circuits.
• Snap-in Package — Radial, can-style snap-in mounting for secure board or chassis installation and straightforward assembly.
• Operating Temperature — Rated for −40 °C to +85 °C, suitable for typical indoor electronics and audio equipment environments.
• Ripple Current — Specified ripple current of 2.7 A at 120 Hz, supporting AC load conditions such as power-supply filtering in amplifiers and audio circuits.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction; intended for DC-biased applications where polarity is observed.
• Endurance — Rated lifetime of 1000 hours at 85 °C when subjected to rated voltage, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Leakage Current Specification — Series leakage current guidance: after 5 minutes’ application of rated voltage at 20 °C, leakage current does not exceed 3√(C·V) µA (C in µF, V in V), per the datasheet series specification.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), suitable for designs requiring restricted-substance conformity.

Typical Applications

• Audio Equipment — Power-supply smoothing and decoupling in amplifiers and audio signal chains; marketed for tone-quality improvement when used to replace smaller standard capacitors.
• Power Supply Filtering — Bulk filtering and reservoir functions in medium-voltage DC rails where polarized electrolytics are appropriate.
• General-Purpose Electronics — Energy storage and decoupling in industrial and consumer electronics designs that accept radial snap-in components.

Unique Advantages

• Audio-focused performance: Specified by the LKS series as “smaller and high-tone quality,” making this part suitable for designers seeking measurable tonal improvements through component upgrades.
• High capacitance in compact form: 3.3 mF of capacitance in a radial snap-in can provides large charge storage without requiring larger multi-component networks.
• Robust ripple handling: 2.7 A ripple current rating at 120 Hz supports demanding filtering tasks in power rails used by audio and amplifier circuits.
• Durability under load: Endurance defined at 1000 hours at 85 °C under rated voltage gives a clear expectation of long-term behavior and stability.
• Regulatory compliance: RoHS conformity simplifies integration into products targeting restricted-substance regulations.
• Secure snap-in mounting: Radial can with snap-in terminals facilitates mechanical retention and repeatable installation in assemblies.
