The VLP8065XT-4R7M and VLP8065T-4R7M are wire-wound power inductors manufactured by TDK Corporation. They are designed for use in DC-DC converters and power management circuits, particularly in applications requiring high current handling and a robust design. These inductors are very similar, and the 'XT' version may have slight differences in materials or construction related to improved performance characteristics. When using either part, consult the specific datasheet for detailed electrical parameters.

Additional Details

Both the VLP8065XT-4R7M and VLP8065T-4R7M inductors utilize a ferrite core material chosen for its magnetic properties and temperature stability. The shielded construction is achieved through a magnetic resin that encapsulates the coil, containing the magnetic field and minimizing EMI. The "4R7M" designation indicates a 4.7 µH inductance value. Consult the respective datasheets for precise electrical characteristics, saturation current, and rated current information as there may be subtle differences between the 'XT' and standard versions.

Specific Electrical Characteristics:

• Inductance: 4.7 µH (measured at a specific frequency, typically 1 MHz)
• DC Resistance (DCR): Check individual datasheets for the exact DCR values for both the XT and non-XT versions.
• Saturation Current (Isat): Consult individual datasheets for Isat.
• Rated Current (Irms): Consult individual datasheets for Irms.
