DR127-2R2-R Frequently Asked Questions (FAQs)

  • The recommended land pattern for the DR127-2R2-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
  • The DR127-2R2-R is rated for operation up to 125°C, but derating is required above 80°C. Consult the datasheet for specific derating guidelines.
  • Handle the DR127-2R2-R by the body, avoiding touching the leads or core. Use ESD protection and follow standard PCB assembly procedures to prevent damage.
  • The ESR of the DR127-2R2-R is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on similar inductors from Coiltronics.
  • The DR127-2R2-R is suitable for high-frequency applications up to several hundred kHz. However, core losses and self-resonance may become significant at very high frequencies (e.g., above 1 MHz).
