1210-472K - API Delevan

1210-472K Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 1210-472K inductor?
  The recommended land pattern for the 1210-472K inductor is a rectangular pad with a size of 1.25 mm x 1.25 mm, with a non-solder mask defined (NSMD) pad shape and a 0.25 mm clearance from the pad to the solder mask.
• Can the 1210-472K inductor be used in high-temperature applications?
  The 1210-472K inductor is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. Consult the manufacturer's application notes for more information.
• How do I handle the 1210-472K inductor's magnetic field in a densely populated PCB?
  To minimize magnetic field interference, keep the 1210-472K inductor at least 2 mm away from other magnetic components, and orient it to minimize flux coupling. You can also use shielding techniques, such as copper pours or magnetic shields, to contain the magnetic field.
• What is the self-resonant frequency (SRF) of the 1210-472K inductor?
  The self-resonant frequency (SRF) of the 1210-472K inductor is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout. Consult the manufacturer's application notes or contact their technical support for more information.
• Can I use the 1210-472K inductor in a high-vibration environment?
  The 1210-472K inductor is designed to withstand moderate vibration levels, but it's recommended to follow the manufacturer's guidelines for vibration testing and to ensure that the PCB is properly secured and supported to prevent mechanical stress on the component.
