Product Overview

The MAG.LAYERS MMD-12FD-SERIES-V1 is a high-performance magnetic metal powder power choke coil designed for a wide range of applications including laptop, desktop, and server systems, as well as high current power supplies and battery-powered devices. These coils feature low resistance and high current ratings, making them suitable for demanding power management integrated circuits (PMICs). They are RoHS compliant and halogen-free.

Product Attributes

• Brand: MAG.LAYERS
• Series: MMD-12FD-SERIES-V1
• Certifications: RoHS compliant & halogen free
• Core Material: High performance magnetic metal powder

Technical Specifications

Test Conditions:

• Test Frequency: 100 KHz, 0.25V
• Inductance/Saturation Current Test Instruments: Keysight 4285A or equivalent
• Rdc Test Instruments: ADEX AX1152D or equivalent
• Ambient Temperature: 25C

Notes:

• Heat rating current (Idc) causes approximately 40C temperature rise.
• Saturation current (Isat) causes approximately 20% initial inductance drop.
• Operating temperature range: -55C to +125C.
• The maximum component temperature (ambient + temperature rise) should not exceed 125C under worst-case conditions.
• Actual component temperature is influenced by application conditions (e.g., circuit design, PCB copper thickness, cooling). Testing in the end application is recommended.

Safety Precautions:

• Avoid placing through holes and copper patterns within the dotted line area, except for connections to electrodes.
• Do not design or mount other components in contact with this product.
• This power choke coil lacks inherent protective functions against abnormal conditions (overload, short circuit, open circuit). The end product must be confirmed to have no risks of smoking, fire, or dielectric breakdown. Protective devices and/or circuits should be incorporated into the end product to ensure safety under abnormal conditions.
