SRR4018-680Y Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with a solid ground plane and a minimum of vias to minimize inductance and ensure optimal performance. A recommended layout is available in the Bourns application note 'Surface Mount Power Inductor Layout Considerations'.
  • The saturation current of the SRR4018-680Y can be determined by using the inductor's DC resistance and the core material's saturation characteristics. Bourns provides a saturation current calculator tool on their website to help with this calculation.
  • The self-resonant frequency of the SRR4018-680Y is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Bourns recommends using a network analyzer to measure the self-resonant frequency for accurate results.
  • The SRR4018-680Y has a maximum operating temperature of 125°C, but derating may be necessary for high-temperature applications. Bourns recommends consulting the datasheet and application notes for temperature derating guidelines.
  • Bourns recommends using a combination of shielding, filtering, and layout techniques to minimize EMI. The SRR4018-680Y's magnetic shielding and low radiation characteristics can help reduce EMI, but additional measures may be necessary depending on the specific application.
