DR127-101-R Frequently Asked Questions (FAQs)

  • Coiltronics recommends a pad layout with a diameter of 0.125 inches (3.18 mm) and a spacing of 0.05 inches (1.27 mm) between pads. A larger pad size can be used for improved solderability.
  • The DR127-101-R is rated for operation up to 125°C. However, the inductor's impedance and inductance may vary by ±15% at high temperatures. It's essential to consider derating and thermal management in high-temperature applications.
  • Coiltronics recommends a soldering profile with a peak temperature of 240°C (464°F) and a dwell time of 3-5 seconds. A slower ramp-up and cool-down rate can help prevent thermal shock.
  • While the DR127-101-R is designed for general-purpose use, it can be used in high-frequency applications up to 1 MHz. However, the inductor's self-resonant frequency (SRF) is around 10 MHz, and its impedance may vary significantly above 1 MHz.
  • The maximum current rating for the DR127-101-R is 1.5 A. However, the inductor's current handling capability may be affected by the PCB layout, ambient temperature, and other environmental factors.
