LKS1J332MESA

The LKS1J332MESA is a Nichicon LKS series snap-in aluminum electrolytic capacitor designed for audio equipment and general-purpose applications. It is a polarized, smaller-sized snap-in radial can intended to improve tone quality when replacing standard small capacitors.

Key attributes include a 3.3 mF (3300 µF) capacitance, 63 V rated voltage, snap-in mounting for secure chassis or PCB installation, and RoHS compliance for regulated production environments.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) nominal capacitance with a 63 V rated voltage and ±20% capacitance tolerance at 120 Hz, 20°C.
• Package & Mounting: Radial can with snap-in terminals for robust mechanical retention and straightforward assembly in power and audio circuits.
• Audio-Focused Design: Marketed for audio equipment as a smaller-sized option intended to deliver a perceived tone-quality improvement when replacing small standard capacitors.
• Thermal & Lifetime Performance: Operates from −40°C to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage.
• Ripple Handling: Rated ripple current of 2.45 A at 120 Hz (low-frequency measurement), suitable for smoothing and filtering in power supply sections of audio gear.
• Leakage Characteristic: Leakage current specified as not more than 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C, per Nichicon test method.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Amplifiers: Bulk smoothing and power decoupling in amplifier power rails where improved tonal characteristics are desired through capacitor replacement.
• Consumer Audio Equipment: Power supply filtering and energy storage in receivers, preamps, and other audio playback devices.
• General Power Filtering: DC link smoothing and ripple suppression in general-purpose power supplies and electronics that require polarized electrolytic capacitors.

Unique Advantages

• Designed for Audio Use: Specified as a smaller-sized, audio-oriented part to help achieve perceptible tone-quality improvements when used in place of standard small capacitors.
• Secure Snap-In Mounting: Snap-in terminal design provides reliable mechanical retention for chassis or PCB installations, simplifying assembly and reducing the need for additional fixtures.
• Robust Ripple Capability: 2.45 A ripple current rating at 120 Hz supports effective smoothing in power-supply applications common to audio gear.
• Wide Operating Range: −40°C to +85°C operating range combined with a 1000-hour endurance rating at 85°C offers predictable performance in typical consumer and pro-audio environments.
• Regulatory Ready: RoHS compliance supports use in regulated manufacturing and reduces material-related compliance work for product teams.
