SRP2010DPA-4R7M - Bourns

SRP2010DPA-4R7M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the power and ground traces as short and wide as possible to minimize inductance and resistance. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
• How do I ensure the inductor is properly soldered to the PCB?
  To ensure proper soldering, Bourns recommends using a soldering iron with a temperature of 250°C to 260°C, and applying a small amount of solder paste to the pads. The inductor should be placed on the PCB with the terminals aligned with the pads, and then soldered using a reflow oven or a hot air soldering technique.
• What is the maximum operating temperature range for this inductor?
  The SRP2010DPA-4R7M has an operating temperature range of -40°C to +125°C, with a maximum storage temperature range of -40°C to +150°C.
• How do I handle the inductor's magnetic field in my design?
  To minimize the effects of the inductor's magnetic field, Bourns recommends keeping the inductor at least 5 mm away from other components that may be affected by the magnetic field, such as transformers, chokes, or other inductors. Additionally, it's recommended to use a shielded inductor or a mu-metal shield to contain the magnetic field.
• What is the recommended current rating for this inductor?
  The SRP2010DPA-4R7M has a recommended current rating of 4.7 A, with a maximum current rating of 6.3 A. Exceeding the recommended current rating may result in reduced performance, increased temperature, and reduced lifespan.
