PTL60-15G1-103B2 - Bourns

PTL60-15G1-103B2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
• How do I ensure the inductor's magnetic field doesn't interfere with nearby components?
  To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
• What is the maximum allowable voltage derating for this inductor?
  Bourns recommends derating the voltage by 10-15% to ensure reliable operation. For the PTL60-15G1-103B2, the maximum allowable voltage is approximately 13.5V (15V x 0.9).
• Can I use this inductor in a high-temperature environment?
  The PTL60-15G1-103B2 is rated for operation up to 125°C. However, it's essential to consider the inductor's temperature coefficient and potential degradation of performance at elevated temperatures. Consult Bourns' application notes for guidance on high-temperature operation.
• How do I determine the inductor's self-resonant frequency (SRF)?
  The SRF is typically not specified in the datasheet. To determine the SRF, you can use a network analyzer or a spectrum analyzer to measure the inductor's impedance vs. frequency. The SRF is the frequency at which the impedance peaks.
