Introduction

Fixed inductors (also known as non-variable inductors) are components used to store energy in an electric or magnetic field. These inductors are commonly found in electronic circuits to provide a combination of both electrical capacitance and inductance which assists in smoothing and regulating voltage, and often are a key device in the design of a“filter” circuit where signals of one frequency are to be isolated from those of another. The S0603-33NF2E is a fixed inductor with an extremely small size (0603) and low self-resonant frequency.

Application Field

The S0603-33NF2E is a high performance, non-polarized, SMD fixed inductor. It was designed specifically for application in DC to DC converters, PLL and RF power amplifiers, as well as in EMICs and other signal conditioning circuits. It features high inductance value (33nH), low DCR (20mΩ max.), and a wide operating temperature range of up -40°C to 125°C.Due to its small size, the S0603-33NF2E is well-suited for high frequency applications where the inductor must fit in small footprints. It guarantees good signal insertion loss performance with minimal thermal effect. Moreover, it is capable of achieving high coupling and low crosstalk in high density applications.

Working Principle

Fixed inductors are based on the principle of electromagnetic induction. When current passes through the coil of wire inside the inductor, a magnetic field is generated. This magnetic field produces an opposing “back-EMF” that opposes the applied current and thus reduces it. The amount of back-EMF generated in the wire is proportional to the amount of change in the applied current, resulting in the production of a counter-effect which is known as “inductance”.This inductance produces a low-pass filter, where high-frequency signals are attenuated relative to the low-frequency signals. It can also be used to provide signal isolation between circuits, as high-frequency signals can be dampened out of the circuit, leaving only the low-frequency signals intact.

Conclusion

The S0603-33NF2E is a fixed inductor designed for a wide range of electronic applications. It has high inductance value (33 nH) and low DCR(20mΩ max.) which makes it an ideal choice for high frequency applications. In addition, its small size allows for a wide range of applications where the component must fit within a small footprint. Finally, its wide operating temperature range (-40°C to 125°C) gives it additional versatility in applications where the environment may be extremely hot or cold.
