LKS1V183MESB

The LKS1V183MESB is an aluminum electrolytic capacitor from Nichicon's LKS series, featuring a snap-in terminal design tailored for audio equipment and smaller-sized applications. It provides 18 mF capacitance at a 35 V rating in a radial, can-style snap-in package, making it suitable for general-purpose power smoothing and audio power-rail applications where compact high-capacitance parts are required.

Designed with a wide operating temperature range and defined endurance, this part balances high capacitance, reliable ripple handling and RoHS compliance for electronics designs that require long-term stability and predictable performance.

Key Features

• Capacitance & Voltage: 18 mF capacitance rated at 35 V for bulk energy storage and smoothing in power rails.
• Package & Mounting: Radial can with snap-in terminals provides secure PCB attachment and easy assembly for through-hole designs.
• Temperature Range: Rated for operation from −40°C to +85°C, supporting a broad set of ambient conditions.
• Endurance: Specified lifetime of 1000 hours at 85°C with capacitance and leakage requirements defined for post-test recovery.
• Ripple Handling: Specified low-frequency ripple current of 4.05 A at 120 Hz, enabling use on power supply outputs and audio amplifier rails.
• Leakage Current Specification: Leakage current after 5 minutes at 20°C is limited to not more than 3√(C·V) μA, where C is capacitance (μF) and V is voltage (V).
• Polarity & Tolerance: Polarized electrolytic design with capacitance tolerance of ±20%.
• Environmental Compliance: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Tone Quality (Series-Level): LKS series is specified as "smaller and high-tone quality" compared with the LKG TYPE-1 grade, indicating suitability for audio-focused applications.

Typical Applications

• Audio Equipment: Bulk decoupling and power-rail smoothing for amplifiers and audio power supplies to support stable audio performance.
• Power Supply Filtering: General-purpose ripple filtering and energy storage on DC supply lines where high capacitance is required in a compact snap-in package.
• Consumer Electronics (Audio-focused): Use in consumer audio products where smaller-sized electrolytics with defined ripple and endurance characteristics are needed.
• General-Purpose Electronics: Circuit designs requiring polarized aluminum electrolytic capacitors for energy storage and transient suppression in through-hole assemblies.

Unique Advantages

• High Capacitance in a Smaller Footprint: 18 mF capacitance in a smaller-sized LKS-series snap-in can enables compact layouts without sacrificing bulk storage.
• Snap-in Mounting for Robust Assembly: Snap-in terminals provide secure mechanical retention for through-hole boards and simplify handling during manufacturing.
• Defined Ripple and Thermal Endurance: Rated ripple current of 4.05 A (120 Hz) and 1000-hour endurance at 85°C provide predictable performance under sustained electrical and thermal stress.
• Measured Leakage Characteristic: Leakage current specified by the 3√(C·V) rule gives a verifiable acceptance criterion for quality control and design validation.
• Series-Level Audio Optimization: LKS-series wording on improved tone quality versus the LKG TYPE-1 grade signals selection preference for audio-centric designs.
• RoHS Compliance: Meets applicable RoHS directives for environmentally restricted substances.
