SRR4028-3R3Y Bourns FIXED IND 3.3UH 2.15A 35MOHM SMD


The part number SRR4028-3R3Y specifies a fixed inductor manufactured by Bourns. Here is a breakdown of its specifications:


  • Manufacturer: Bourns
  • Type: FIXED IND (Fixed Inductor)
  • Inductance: 3.3 µH (microhenries)
  • Current Rating: 2.15A (Amperes)
  • DC Resistance: 35 mOhms (milliohms)
  • Package: SMD (Surface Mount Device)

This fixed inductor is designed to have an inductance of 3.3 µH, allowing it to store energy in a magnetic field when current flows through it. The current rating of 2.15A specifies the maximum continuous current that the inductor can handle without exceeding its temperature and performance limits.

The DC resistance of 35 mOhms represents the resistance to the flow of direct current through the inductor. This value is important as it affects the overall circuit's impedance and power dissipation.

The SMD package type indicates that the inductor is designed for surface-mount applications, making it suitable for use on printed circuit boards and other electronic assemblies.

Overall, the SRR4028-3R3Y inductor from Bourns is designed for various electronic applications and is most suitable for use in power supplies, DC-DC converters, voltage regulation, filtering, and other circuit designs where inductors are necessary.
