DR1040-100-R - Eaton

DR1040-100-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the DR1040-100-R?
  The recommended PCB land pattern for the DR1040-100-R can be found in the Coiltronics application note AN-013, which provides detailed guidelines for PCB layout and footprint design.
• How does the DR1040-100-R perform in high-temperature environments?
  While the datasheet specifies an operating temperature range of -40°C to +125°C, Coiltronics recommends derating the inductor's current rating by 1.5% for every degree above 80°C to ensure reliable operation in high-temperature environments.
• Is the DR1040-100-R compatible with high-frequency switching applications?
  Yes, the DR1040-100-R is designed to handle high-frequency switching applications up to 1 MHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that the switching frequency is below the SRF to avoid potential resonance issues.
• What is the recommended storage and handling procedure for the DR1040-100-R?
  Coiltronics recommends storing the DR1040-100-R in a dry, cool place, away from direct sunlight and moisture. Handling should be done with electrostatic discharge (ESD) precautions, such as using ESD-safe gloves and wrist straps, to prevent damage to the component.
• Can the DR1040-100-R be used in automotive applications?
  While the DR1040-100-R meets the general requirements for automotive applications, it's essential to verify that the component meets the specific requirements of the target application, including AEC-Q200 qualification and PPAP documentation, if required.
