The DO3340P-103MLD is a shielded power inductor manufactured by Coilcraft, designed for various power supply and filtering applications. It is particularly suitable for use in high-frequency DC-DC converters due to its low core loss and shielded construction. The inductor is categorized as END-OF-LIFE, which means it is no longer actively manufactured by Coilcraft.

Applications

• DC-DC Converters: Widely used in buck, boost, and flyback converters for power regulation.
• Voltage Regulators: Providing stable voltage output in various electronic devices.
• EMI Filtering: Reducing electromagnetic interference in electronic circuits.
• Power Amplifiers: Used in power amplifiers to filter unwanted noise.
• LED Lighting: Providing stable and efficient power to LED drivers.

Features

• Shielded Construction: Minimizes electromagnetic interference (EMI) radiation.
• Low DC Resistance (DCR): Reduces power loss due to resistance, increasing efficiency.
• High Saturation Current: Allows for high current handling without significant inductance drop.
• Compact Size: Suitable for applications where space is limited.
• High Frequency Performance: Designed for efficient operation at high switching frequencies.

Benefits

• Reduced EMI: Shielded construction minimizes interference with other components.
• Improved Efficiency: Low DCR reduces power loss and improves overall efficiency.
• Stable Performance: High saturation current ensures stable inductance under high current conditions.
• Compact Design: Small size allows for integration into portable and space-constrained devices.

Additional Details

Key specifications of the DO3340P-103MLD include its inductance value (10μH), saturation current, DC resistance, and operating frequency range. When selecting a replacement inductor, it is important to consider these specifications to ensure compatibility with the existing circuit. Given its END-OF-LIFE status, finding an exact replacement might be difficult. It is recommended to check with electronic component distributors for available stock or to consider alternative inductors with similar specifications from Coilcraft or other manufacturers. The datasheet from Coilcraft provides detailed electrical and mechanical information about the inductor.
