DR125-220-R - Eaton

DR125-220-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the DR125-220-R?
  The recommended PCB land pattern for the DR125-220-R is a rectangular pad with dimensions of 3.8mm x 2.5mm, with a 1.3mm x 1.3mm thermal pad in the center. The pad should be solder-mask defined and have a non-solder-mask-defined (NSMD) thermal pad.
• How do I handle the thermal considerations for the DR125-220-R?
  To ensure proper thermal performance, it's recommended to provide a solid copper plane under the inductor, connected to a thermal relief pad. This helps to dissipate heat generated by the inductor. Additionally, ensure good airflow around the component and avoid placing heat-sensitive components nearby.
• What is the maximum operating temperature range for the DR125-220-R?
  The maximum operating temperature range for the DR125-220-R is -40°C to +125°C. However, the inductor's performance may degrade at extreme temperatures, so it's essential to consider the specific application requirements and potential temperature fluctuations.
• Can I use the DR125-220-R in a high-vibration environment?
  While the DR125-220-R is designed to be robust, it's still important to consider the vibration requirements of your specific application. Coiltronics recommends following the IPC-J-STD-001 standard for vibration testing. If your application exceeds these standards, consult with Coiltronics or a qualified engineer for guidance.
• How do I ensure the DR125-220-R meets my specific EMI requirements?
  To minimize EMI, ensure proper PCB layout and routing, keeping the inductor away from sensitive components and traces. Use shielding or EMI-absorbing materials if necessary. Additionally, consider using a common-mode choke or other EMI-filtering components in conjunction with the DR125-220-R.
