SRN2012T-100K - Bourns

SRN2012T-100K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
• How do I ensure the inductor is properly soldered to the PCB?
  Use a soldering iron with a temperature of 250°C to 260°C, and apply a small amount of solder to the pads. Ensure the inductor is centered and evenly spaced on the pads to prevent thermal stress.
• What is the maximum allowable voltage across the inductor?
  The maximum allowable voltage across the SRN2012T-100K is 100V, but it's recommended to derate the voltage by 10-20% to ensure reliable operation and prevent premature failure.
• Can I use this inductor in a high-temperature environment?
  The SRN2012T-100K 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.
• How do I calculate the self-resonant frequency of the inductor?
  The self-resonant frequency can be calculated using the formula: f_res = 1 / (2 * π * √(L * C)), where L is the inductance and C is the parasitic capacitance. For the SRN2012T-100K, the parasitic capacitance is approximately 0.15nF.
