The SDR0403-1R4ML is a type of Fixed Inductor which is employed in numerous applications. Fixed Inductors offer excellent performance in a remarkably compact form. This makes them highly reliable and suitable for use in a wide range of applications. This article will provide an overview of the application field and working principle of the SDR0403-1R4ML.
Application Field:
The SDR0403-1R4ML is ideally suited for use in both high-frequency filter circuits and DC/DC converters. It has a maximum operating temperature of 80°C, allowing it to be used in harsh, high-temperature environments. Additionally, its low vertical dimension minimizes parasitic capacitance for a higher SRF than traditional inductors. This makes it the perfect choice for high-bandwidth applications, such as RF filters, high-frequency switching power supplies and transceivers.
Working Principle:
The SDR0403-1R4ML works on the principle of an electromagnetic coil with a core of soft ferrite. An alternating current is passed through the coil, and this generates a magnetic field around the core. This causes eddy currents to be induced in the ferrite core, which oppose the alternating current. This resistive force of opposition generates an inductive effect, which can be measured as a voltage. This voltage is known as the inductor\'s inductance.
The inductance of the SDR0403-1R4ML can be further modified by the addition of external magnetic cores. This allows the user to optimize the inductor for specific applications and to further increase the inductance or reduce the DCR.
Finally, the size and shape of the SDR0403-1R4ML makes it easy to install in tight spaces. Its small footprint also allows for better cooling and increased longevity.
Conclusion
In conclusion, the SDR0403-1R4ML is an exceptionally versatile Fixed Inductor with a wide range of applications. It offers reliable performance, excellent SRF and a low vertical profile. Additionally, its external magnetic cores can be used to customize its inductance to fit specific applications. It is ideal for high-frequency filter circuits and DC/DC converters, and its small size and shape makes it easy to install in tight spaces.
