PM1008S-100M-RC - Bourns

PM1008S-100M-RC 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 optimal performance, low inductance, and minimal signal degradation.
• How do I ensure the inductor's self-resonant frequency (SRF) doesn't affect my circuit's performance?
  To minimize the impact of SRF, ensure the inductor is used below its SRF. You can also use a series resistor or a parallel capacitor to dampen the resonance. Additionally, consider using a shielded inductor or a different inductor with a higher SRF.
• What is the maximum current rating for this inductor, and how does it affect the temperature rise?
  The maximum current rating for the PM1008S-100M-RC is 10.4A. Exceeding this rating can cause excessive temperature rise, which can lead to reduced lifespan or even failure. Ensure your design stays within the recommended current rating to maintain reliability.
• How do I handle the inductor's DC resistance (DCR) in my design?
  The DCR of the PM1008S-100M-RC is 12.5 mohms. You should consider this value when calculating power losses and heat dissipation in your design. You may need to adjust your design to accommodate the DCR, especially in high-current or high-frequency applications.
• Are there any special considerations for storage and handling of these inductors?
  Yes, it's essential to handle the inductors with care to prevent mechanical damage. Store them in a dry, cool place, away from direct sunlight and moisture. Avoid bending, flexing, or applying excessive force, which can cause damage to the internal windings or terminations.
