CTX20-2P-R - Eaton

CTX20-2P-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and footprint for optimal performance?
  Coiltronics recommends a PCB layout with a solid ground plane and a footprint with a minimum of 10 mils (0.25 mm) clearance around the component. A recommended footprint can be found in the Coiltronics application note AN-001.
• How do I ensure proper thermal management for this inductor?
  Proper thermal management can be achieved by providing adequate airflow, using a thermal interface material (TIM) between the inductor and the PCB, and keeping the ambient temperature within the recommended operating range. Coiltronics recommends a maximum temperature rise of 40°C above ambient.
• What is the maximum allowable voltage stress for this inductor?
  The CTX20-2P-R is rated for a maximum voltage stress of 1.5 times the rated voltage for a maximum of 10 seconds. Exceeding this voltage stress may result in reduced reliability or even failure.
• Can I use this inductor in a high-frequency application (>1 MHz)?
  While the CTX20-2P-R is designed for high-frequency applications, its performance may degrade above 1 MHz due to core losses and skin effect. Coiltronics recommends consulting with their application engineers for high-frequency applications.
• How do I handle the inductor's magnetic field in a densely populated PCB?
  To minimize magnetic field interference, Coiltronics recommends keeping the inductor at least 10 mm away from sensitive components, using shielding, and orienting the inductor to minimize field strength in the direction of sensitive components.
