Fixed Inductors

SP1210-104K is a type of fixed inductor invented by AVX Corporation, a company that produces electronic components for vehicles, computers, medical devices and other applications. These inductors are designed to provide a reliable, cost-effective solution for high-frequency circuits.

Application Field of SP1210-104K

SP1210-104K fixed inductors offer a wide range of applications and can be used in various systems, such as cellular, PCS and other two way radio applications. They are also suitable for power supplies, switching regulators, flyback converters, SMPS, motor control applications and many more.

The SP1210-104K is designed to provide power and noise suppression in noisy electronic environments. Thanks to the enclosed core construction, the inductor can survive high temperatures over 85°C and boasts an excellent thermal characteristics. Furthermore, the minimum self-resonant frequency of the device is much higher than regular inductors.

Working Principle of SP1210-104K

A fixed inductor relies on the Faraday induction law stating that an induced EMF is generated in a loop of wire either when the current flowing through the wire loop changes or when a magnet approaches or recedes from the loop. The SP1210-104K applies this principle in its operation.

The electronic component is configured with two permalloy and two MM5269 bases connected in series. The MM5269 is a high electromagnetic induction material with a permeability of up to 2000, which makes it ideal to provide maximum inductance for a given size. The permalloy allows for effective high frequency operation due to its low core losses at high frequencies.

The two permalloy bases are used to suppress high frequency noise in the circuit, while the two MM5269 bases act as the main inductor, providing the required DC inductance value. Also, the component is provided with two 9411 terminals for 2-way electrical connection, enabling the inductor to be used in diverse applications.

Conclusion

The SP1210-104K fixed inductor is a highly efficient electronic component suitable for a wide range of applications, such as cellular, PCS, power supplies, switching regulators, flyback converters, SMPS, motor control and many more. This device works in accordance with the Faraday induction law and is composed of two permalloy and two MM5269 bases connected in series. By utilizing this component, manufacturers are able to achieve high performance, reliable, and cost-effective solutions in electronic assemblies of all kinds.
