PWR263S-20-1R50JE - Bourns

PWR263S-20-1R50JE Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the PWR263S-20-1R50JE?
  The recommended PCB footprint for the PWR263S-20-1R50JE is a rectangular pad with dimensions of 4.5 mm x 3.5 mm, with a 1.1 mm diameter hole in the center for the inductor's lead.
• How do I ensure the inductor's magnetic field does not interfere with nearby components?
  To minimize magnetic field interference, keep the inductor at least 5 mm away from sensitive components, and consider using a shielded inductor or a mu-metal shield around the inductor.
• What is the maximum operating temperature range for the PWR263S-20-1R50JE?
  The maximum operating temperature range for the PWR263S-20-1R50JE is -40°C to +125°C, with a derating of inductance and saturation current above 85°C.
• Can I use the PWR263S-20-1R50JE in a high-vibration environment?
  Yes, the PWR263S-20-1R50JE is designed to withstand vibrations up to 10 G's, but it's recommended to secure the inductor to the PCB using a suitable adhesive or mechanical fastening to prevent movement.
• How do I calculate the inductor's core loss at high frequencies?
  Use the inductor's core loss data provided in the datasheet, and calculate the core loss using the formula: P_core = (Irms^2 * R_core) + (Iac^2 * X_core), where Irms is the RMS current, R_core is the core resistance, Iac is the AC current, and X_core is the core reactance.
