IHTH0750JZEB101M5A datasheet by Vishay Dale

IHTH0750JZEB101M5A Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Vishay provides a recommended PCB layout and land pattern in their application note AN1025, which can be found on their website. Following this layout ensures optimal thermal performance and minimizes parasitic inductance.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize magnetic field interference, keep the inductor at least 5 mm away from sensitive components, such as oscillators, antennas, or magnetically sensitive devices. You can also use shielding techniques, like mu-metal or ferrite sheets, to contain the magnetic field.
• What is the maximum allowed voltage across the inductor during saturation?
  Although the datasheet doesn't specify a maximum allowed voltage during saturation, it's generally recommended to limit the voltage to 1.5 to 2 times the nominal voltage rating to prevent damage to the inductor. In this case, the maximum allowed voltage would be around 37.5 V to 50 V.
• How do I calculate the inductor's self-resonant frequency (SRF)?
  The SRF can be estimated using the formula: SRF ≈ (1 / (2 * π * √(L * C))), where L is the inductance and C is the equivalent series capacitance (ESC). The ESC can be found in the datasheet or calculated using the inductor's physical dimensions and materials.
• What is the inductor's thermal resistance (Rth) and how does it affect the design?
  The thermal resistance (Rth) of the IHTH0750JZEB101M5A is approximately 2.5°C/W. This value indicates how much the inductor's temperature will rise above the ambient temperature for a given power dissipation. You should consider Rth when designing the system to ensure the inductor operates within its specified temperature range.
