2DM180506CM - Tamura

2DM180506CM Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Tamura recommends a PCB layout with a solid ground plane and a thermal pad connected to a heat sink or a thermal via to ensure efficient heat dissipation. A minimum of 2oz copper thickness is recommended for the PCB.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize magnetic field interference, Tamura suggests keeping the inductor at least 5mm away from nearby components, using a shielded inductor, or orienting the inductor to minimize the magnetic field's impact on surrounding components.
• What is the maximum allowable voltage stress on the inductor during switching transients?
  Tamura recommends limiting the voltage stress to 1.5 times the rated voltage to prevent damage to the inductor. Exceeding this limit may lead to reduced lifespan or failure.
• How do I determine the inductor's self-resonant frequency and its impact on the circuit?
  The self-resonant frequency can be determined using the inductor's datasheet values and the PCB's parasitic capacitance. A self-resonant frequency close to the switching frequency can cause oscillations and affect circuit performance. Tamura recommends using a series resistor or a damping network to mitigate these effects.
• What is the recommended storage and handling procedure to prevent damage to the inductor?
  Tamura recommends storing the inductor in a dry, cool place, away from direct sunlight and moisture. Handling should be done with care to avoid mechanical stress, and the inductor should not be exposed to excessive vibration or shock.
