SRN6045-470M - Bourns

SRN6045-470M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the SRN6045-470M?
  A good PCB layout for the SRN6045-470M would involve keeping the inductor away from high-current carrying traces, using a solid ground plane, and minimizing the distance between the inductor and the capacitor to reduce parasitic inductance.
• How do I determine the saturation current of the SRN6045-470M?
  The saturation current of the SRN6045-470M can be determined by applying a DC current to the inductor and measuring the inductance using an LCR meter or an impedance analyzer. The current at which the inductance starts to drop significantly is the saturation current.
• What is the self-resonant frequency of the SRN6045-470M?
  The self-resonant frequency of the SRN6045-470M is not explicitly stated in the datasheet, but it can be estimated using the formula: f_res = 1 / (2 * pi * sqrt(L * C)), where L is the inductance and C is the parasitic capacitance of the inductor.
• Can I use the SRN6045-470M in a high-temperature environment?
  The SRN6045-470M has a maximum operating temperature of 125°C, but the inductor's characteristics may change at high temperatures. It's recommended to derate the inductor's current rating and inductance value according to the temperature derating curve provided in the datasheet.
• How do I handle the radiated emissions from the SRN6045-470M?
  To minimize radiated emissions from the SRN6045-470M, use a shielded inductor or add a shield around the inductor, keep the inductor away from sensitive circuits, and use a common-mode choke to filter out common-mode noise.
