LKS1K332MESZ

The LKS1K332MESZ is an aluminum electrolytic capacitor in Nichicon’s LKS series, featuring a snap-in terminal configuration optimized for audio equipment and smaller-sized assemblies. It delivers 3.3 mF capacitance with an 80 V rating and is intended as a direct replacement or upgrade from smaller standard parts to improve tone quality in audio applications.

Designed for general-purpose use, the component combines polarized aluminum electrolytic construction with series-level endurance and environmental compliance to meet common engineering requirements in audio and related power-supply circuits.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) nominal capacitance with an 80 V rated voltage suitable for higher-voltage audio and power applications.
• Tolerance & Polarization — Capacitance tolerance of ±20% (measured at 120 Hz, 20°C). This is a polarized capacitor and must be installed with correct polarity.
• Mounting & Package — Snap-in terminal, radial can (snap-in) package for secure chassis/board installation and straightforward replacement workflows.
• Temperature Range & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage conditions.
• Ripple Current & Leakage — Low-frequency ripple capability of 3 A at 120 Hz and leakage current specified as not more than 3√(C·V) μA after 5 minutes at 20°C (C in μF, V in volts).
• Physical Size & Marking — Compact dimensions (L: 5 × D: 2.2 cm) and printed marking in silver on a black sleeve for easy identification.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting current restricted-substance directives.

Typical Applications

• Audio Equipment — Use as an upgrade or replacement capacitor to achieve measurable tone-quality improvement in amplifiers and audio power circuits.
• General-Purpose Power Supply — Suitable for general-purpose circuits requiring polarized aluminum electrolytic capacitors within the specified voltage and temperature ranges.
• Equipment Replacement/Retrofit — Smaller-sized snap-in form factor makes it practical for replacing older or smaller standard parts in existing designs to enhance performance.

Unique Advantages

• Audio-focused series design — LKS series orientation toward audio equipment supports replacement-driven tone-quality improvements.
• High-voltage capability — 80 V rating allows use in higher-voltage sections of audio and power-supply designs compared with lower-voltage options.
• Snap-in mounting — Robust snap-in terminals enable reliable mechanical retention and simplified assembly in chassis or board-level installations.
• Measurable ripple handling — Rated for 3 A at 120 Hz, providing defined low-frequency ripple capability for power smoothing applications.
• Defined endurance — 1000 hours at 85°C under rated voltage gives a clear expectation of long-term performance in warm operating environments.
• Regulatory compliance — RoHS conformity supports deployment in designs requiring restricted-substance compliance.
