• Highly efficient
• High current capability
• High voltage capability
• High inductance stability over temperature range
• Excellent power handling
• Low profile
• High EMI shielding

The SRU8045A-4R7Y fixed inductor is constructed of two concentric layers of ceramic cores and radially leaded inductor coils. The coils are wound with insulated copper wire, and the cores are composed of a stack of ferrite materials. This stack is then bonded together and then sintered in an oven. The core construction ensures excellent temperature stability and allows for the very low-profile construction.

The working principle of the SRU8045A-4R7Y is based on Faraday’s law of induction. This states that when a current changes, a magnetic field is generated in the area around the wire that contains the current. This magnetic field will induce a voltage in any conductive material that is within the field. The SRU8045A-4R7Y harnesses this induced voltage as a means of providing a reliable power source for applications.

The SRU8045A-4R7Y fixed inductor provides an excellent solution for powering both stationary and mobile applications that require high-performance and reliability. Its low-profile construction allows for easy integration into tight spaces, and its high frequency and temperature stability make it an ideal choice for a wide range of applications. This component is available in a range of standard values, allowing for easy selection of the right inductor for any design requirement.
