SRN4018-101M Frequently Asked Questions (FAQs)

  • Bourns provides a recommended PCB layout and land pattern in their application notes and design guides. It's essential to follow these guidelines to ensure optimal performance, low EMI, and high reliability.
  • To minimize the impact of SRF, ensure the inductor is used below its SRF, and consider adding a decoupling capacitor to filter out high-frequency noise. Additionally, use a shielded inductor or a ferrite bead to reduce EMI.
  • The SRN4018-101M has an operating temperature range of -40°C to +125°C. However, derating may be necessary for high-temperature applications. Consult the datasheet and Bourns' application notes for more information.
  • The SRN4018-101M is designed to withstand moderate vibration and shock. However, for extreme environments, consider using a more ruggedized inductor or adding additional mechanical support to ensure reliability.
  • Determine the required inductance value based on your circuit's operating frequency, current, and voltage. Consult the datasheet and Bourns' application notes for guidance on selecting the optimal inductor value.
