LKX2D102MESC30

The LKX2D102MESC30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKX series, engineered for audio equipment and switching power supply applications. It combines a 200 V rated voltage with 1 mF capacitance and a 105°C rated temperature range for reliable performance in demanding power environments.

Designed as part of Nichicon’s 105°C standard series, this capacitor uses selected materials to support superior acoustic sound and meets RoHS directive requirements.

Key Features

• Capacitance and Voltage: 1 mF capacitance rated at 200 V, suitable for higher-voltage rail applications.
• High Temperature Endurance: Rated for operation from –40°C to 105°C with a specified lifetime of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability: Handles 2.3 A at 120 Hz and 3.45 A at 50 kHz, with frequency coefficients provided in the LKX series datasheet for other frequencies.
• Snap-In Mounting: Radial, can-style snap-in package for secure PCB mounting in power assemblies.
• Audio-Optimized Materials: Selected materials in the LKX series are specified to achieve superior acoustic sound for audio equipment applications.
• Leakage Current Specification: Leakage current defined in the datasheet as I ≤ 3√3V (μA) after 5 minutes application of rated voltage at 20°C.
• RoHS Compliance and Marking: Compliant with RoHS (2011/65/EU, (EU)2015/863) and marked with gold lettering on a black sleeve.

Typical Applications

• Audio Equipment (Switching Power Supplies): Bulk and filtering capacitance in audio switching power supplies where acoustic quality and thermal endurance are required.
• Switching Power Supplies: DC link and smoothing applications on 200 V rails that demand high ripple handling and 105°C operation.
• General Purpose Power Filtering: General-purpose use in industrial and electronic equipment where a robust, polarized aluminum electrolytic with snap-in mounting is preferred.

Unique Advantages

• 200 V Rated Voltage: Supports higher-voltage rails without needing parallel components or series stacks.
• Designed for 105°C Operation: 2000-hour endurance at 105°C under rated conditions provides predictable life for thermal-stressed designs.
• High Ripple Handling: Specified ripple currents at 120 Hz and 50 kHz allow designers to size the capacitor confidently for both low- and high-frequency power systems.
• Audio-Focused Material Selection: Materials in the LKX series are selected to contribute to superior acoustic sound where audio fidelity is a design consideration.
• Snap-In Package for Secure Mounting: Radial can with snap-in terminals simplifies mechanical retention on power PCBs and assemblies.
• Regulatory Compliance: RoHS compliant for use in designs requiring lead-free compliant components.
