The SPT30L-522MLD is a surface mount power inductor manufactured by Coilcraft. It's designed for use in high-frequency DC-DC converters and power supply applications where a low-profile and high-efficiency inductor is required.

Applications:

• DC-DC converters in portable devices
• Power supplies for notebooks and tablets
• Point-of-Load (POL) regulators
• Filtering in power circuits
• Buck-Boost converters

Features:

• Low profile for space-constrained applications
• High saturation current capability
• Shielded construction for low EMI
• Excellent current handling capabilities
• Optimized for high-frequency operation

Benefits:

• Allows for smaller and thinner power supply designs.
• Reduces core losses and improves overall efficiency.
• Minimizes electromagnetic interference, enhancing system stability.
• Handles large currents without significant performance degradation.
• Enables high-frequency switching, reducing the size of other components.

Technical Specifications:

The SPT30L-522MLD typically features an inductance of 5.2 μH with a tolerance. The dimensions are small, typically under 3mm in height. The saturation current (Isat) and RMS current (Irms) are critical parameters for determining its current handling capability. The DC resistance (DCR) influences the inductor's efficiency. The operating temperature range typically spans from -40°C to +85°C or higher. The specific values for Isat, Irms, and DCR are available in the official Coilcraft datasheet, which should be consulted for design purposes.
