DR127-681-R - Eaton

DR127-681-R Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the DR127-681-R?
  The recommended PCB land pattern for the DR127-681-R is a rectangular pad with a size of 3.8mm x 2.5mm, with a 1.3mm diameter hole in the center for the pin. The pad should be solder-mask defined (SMD) with a non-solder-mask-defined (NSMD) pin 1 indicator.
• Can I use the DR127-681-R in a high-temperature environment?
  The DR127-681-R is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation. Consult the Coiltronics application note for high-temperature operation guidelines.
• How do I handle the DR127-681-R for optimal reliability?
  To ensure optimal reliability, handle the DR127-681-R by the body, avoiding touching the leads or core. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage. Store the components in a dry, cool place, away from direct sunlight.
• What is the equivalent series resistance (ESR) of the DR127-681-R?
  The ESR of the DR127-681-R is not explicitly stated in the datasheet, but it can be estimated to be around 0.1-0.2 ohms based on the inductor's design and materials. For more accurate ESR values, consult Coiltronics' application notes or contact their technical support.
• Can I use the DR127-681-R in a high-vibration environment?
  The DR127-681-R is designed to withstand moderate vibration levels, but it's recommended to consult Coiltronics' vibration testing data and application notes for specific guidance on using the component in high-vibration environments.
