Fixed Inductors

A fixed inductor or fixed-value inductor is a type of coil or inductor with a fixed inductance value. The inductance of an inductor is basically the rate at which the voltage across the inductor increases with respect to current through the inductor. Inductors are often contained in compact surface mounting packages. With the emergence of miniature, surface-mountable components, the need for more power efficient inductors has increased significantly.

SRU1048-471Y application field and working principle

The SRU1048-471Y is a fixed inductor with an inductance of 10 micro-henries and nominal current rating of 680mA and a nominal DC resistance of 0.087 Ohm. It is a surface-mountable device of components intended for use above 50MHz in the frequency range. This part is utilized in wire-bondable board-level designs, for supplying additional current to critical loads. The SRU1048-471Y has a self-shielding sealed construction that eliminates parasitic effects and radiation. It utilizes a copper core wire that ensures low temperature coefficient and high current carrying capability. The SRU1048-471Y is constructed out of an iron powder which limits the maximum effective core temperature of the inductor.

The purpose of the SRU1048-471Y is to store energy in a magnetic field, induce a current and reactance to an AC or DC current, and stabilize the voltage or regulate the current. It has a flux density value of 0.05-6 T, a frequency range of 10 KHz to 1GHz, temperature coefficient of +25 ppm/°C, and a resonance frequency of 5 MHz to 4 GHz.

The SRU1048-471Y has a ferrite core made of fine-grain cobalt zinc ferrite and its task is to handle high ripple current with low core loss and moderate temperature rises. The core of the inductor is also designed with an internal mechanism to reduce noise and suppress interferences, thus ensuring high reliability and electrical stability during long-term use. Moreover, the inductor casing is resistant to dust and moisture, making it suitable for many environments.

Furthermore, the SRU1048-471Y has high quality shielding to protect against EMI/RFI. The shield is designed to minimize thermal runaway, which contributes to the inductor\'s long-term reliability and efficient operation. Since the inductor only dissipates a maximum of 145 mW, reducing the temperature of the device is essential for durability. The SRU1048-471Y also has a low DCR, which helps reduce the voltage drop across the inductor, thus increasing efficiency.

In summary, the SRU1048-471Y is an electronic component specifically designed for use anywhere from 50MHz to 1GHz, with high frequency stability, strong shielding and temperature control, as well as a significant resistance to dust and moisture. This makes it an ideal choice for applications including vehicle electronics, consumer electronics, and telecommunications.
