LKS1H392MESZ

The LKS1H392MESZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose applications where a smaller-sized, performance-focused capacitor is required. It combines a compact radial, can-style snap-in package with specifications targeted at power filtering and tone-quality improvement.

This part delivers 3.9 mF capacitance at a 50 V rated voltage, polarized construction, and RoHS compliance, making it suitable for designers seeking a compact upgrade from standard small capacitors in audio and general-purpose power circuits.

Key Features

• Core Type Aluminum electrolytic, polarized component suitable for power filtering and energy storage in audio and general-purpose circuits.
• Electrical Rating 3.9 mF capacitance at 50 V rated voltage with ±20% tolerance (measured at 120 Hz, 20°C).
• Mounting & Package Radial, can-style snap-in package for secure chassis/PCB mounting; package dimensions L: 3.5 × D: 2.2 cm with a maximum seated height of 1.378 inch.
• Ripple Handling Low-frequency ripple current rating of 2.3 A at 120 Hz, suitable for smoothing and decoupling tasks in power rails.
• Operating Temperature & Endurance Category temperature range of −40°C to +85°C and qualified for 1000 hours at 85°C per the LKS series endurance specification.
• Leakage & Stability Series leakage current specification: after 5 minutes at rated voltage and 20°C, leakage current is not more than 3√CV (μA) [C: μF, V: V]; endurance limits include capacitance change within ±20% and tan δ up to 200% of initial specified value after endurance conditions.
• Regulatory Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Intended for use in audio circuits where replacing a small standard capacitor can yield a measurable effect on tone quality.
• General-Purpose Power Filtering — Used for smoothing and decoupling in power supply rails within general-purpose electronic equipment.
• Component Upgrades and Retrofits — Compact snap-in form factor enables upgrades from smaller standard products to improve performance without major layout changes.

Unique Advantages

• Compact, Snap-in Packaging: Radial can with snap-in terminals provides secure mechanical retention while saving board space compared with larger can-style parts.
• Designed for Audio Tone Improvement: Series description highlights suitability for audio equipment and tone-quality improvement when used as a replacement for smaller standard capacitors.
• Robust Ripple Capability: 2.3 A ripple current at 120 Hz addresses needs of power rails requiring effective AC disturbance handling.
• Wide Operating Range and Proven Endurance: −40°C to +85°C operating range and 1000-hour endurance at 85°C give predictable performance across typical environmental conditions.
• Measured Leakage Specification: Leakage current defined by 3√CV formula after rated-voltage application enables predictable leakage behavior for design calculations.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances.
