Fixed inductors such as the SC414MF-680 are an essential component for many electronic circuits. When deployed correctly, they can help shape the current and voltage in a circuit, improve safety, and filter out interference. Additionally, they help reduce radiated emissions, making them a valuable tool when considering both EMC and emissions requirements.
Mounting and Terminations
A common mounting type for the SC414MF-680 is through-hole, which allows it to be directly soldered to a PCB. This style is perfect for both prototyping and cost-effective manufacturing in high-volume and also enables the inductor to be easily re-positioned during repairs or maintenance further down the line. Also, since the inductor is held securely, it is unlikely to vibrate, negating the potential for mechanical failure to occur. The inductor also features flexible lead terminations.
Application Fields
The SC414MF-680 is suitable for applications such as high-density DC/DC converters, fuel-cell regulators, and digital camera designs. Additionally, it is suitable for use in automotive applications due to its AEC-Q200 qualification and wide operating temperature range of -40 °C to +125 °C. Other applications include: AC/DC power supplies, stepper motor drivers, and switching power supplies.
Working Principle
A basic circuit diagram of a fixed inductor using the SC414MF-680 illustrates the principle of its operation. The inductor works by responding to changing currents and allowing or obstructing the flow in the circuit, thus creating a low pass filter. In simpler terms, as current passes through the inductor, it creates a magnetic field which surrounds the inductor and opposes any changes in current. This opposing force is known as inductor reactance. For instance, if the current increases, the reactance of the inductor will also increase proportionately and this higher resistance will limit or reduce the amount of current flowing through the circuit. This principle is also seen on AC/DC power adapters, as the inductor helps reduce the ripple noise generated by the lower frequencies.
Conclusion
The SC414MF-680 fixed inductor is a highly versatile component and is suitable for a variety of uses when it comes to power conversion in both AC/DC and DC/DC circuits. Its through-hole mounting feature and wide operating temperature make it suitable for use in both low- and high-volume applications, while its reactance helps reduce radiated emissions and interference, making it a desirable component whenever electromagnetic compatibility and emissions requirements must be considered.
