SF2259H Frequently Asked Questions (FAQs)

  • Murata recommends a symmetrical PCB layout with a solid ground plane, and the use of vias to connect the component pads to the ground plane to reduce electromagnetic interference (EMI).
  • Murata recommends using a reflow soldering process with a peak temperature of 260°C (500°F) and a dwell time of 30-60 seconds. Hand soldering is not recommended due to the component's small size and high pin density.
  • While the datasheet specifies an operating temperature range of -40°C to 85°C, Murata recommends derating the component's performance at temperatures above 70°C (158°F) to ensure reliable operation.
  • Murata recommends storing the SF2259H in a dry environment with a relative humidity of 60% or less, and baking the components at 125°C (257°F) for 24 hours before reflow soldering to remove any moisture.
  • Murata recommends powering up the SF2259H's input voltage (VIN) before the enable pin (EN) to prevent unwanted current draw and ensure proper startup.
