103-681FS

Fixed inductors are essential components in a range of electronics applications, from high-end audio systems to industrial machinery. As a key component in electromagnetic compatibility (EMC) designs, they are used to control the amount of current or voltage that is allowed to pass through a circuit. This article will explain the application field and working principle of the 103-681FS fixed inductor.

Overview of 103-681FS

The 103-681FS is a medium-sized, radial-lead, fixed-inductor designed primarily for use with power supplies, audio systems, and similar industrial equipment. It can handle up to 3.5A at a maximum temperature of 85° Celsius and provides great protection against EMI. The 103-681FS has a ceramic, ferrite core with isolation-yet-proper-resilience, it is RoHS compliant and UL 94V-0 approved, which makes it an ideal choice for many applications.

Application field of 103-681FS

The 103-681FS is ideal for use in a wide range of applications including but not limited to industrial equipment, medical equipment, power switching circuits, switch-mode power supplies, and audio amps. Its key features enable it to be suitable for many different applications. Its high current rating makes it suitable for use in high power circuits, while its low EMI emissions make it ideal for use in EMC designs. Its RoHS compliance also makes it suitable for use in green manufacturing processes.

Working principle of 103-681FS

The 103-681FS is a fixed inductor, which means it is designed to maintain a fixed level of electrical current or voltage in a circuit. The inductor is primarily composed of a ferrite core and several windings of wire around the core. The windings create an inductance which acts to limit or moderate the passage of current or voltage through the circuit, thus controlling the magnitude and duration of current or voltage in the system. The inductance can also influence other parameters such as frequency, impedance, phase shift and resonance.

The 103-681FS is designed to control voltage within the 85° Celsius temperature range. As the temperature rises within the range, the inductance of the inductor decreases. This decrease in inductance allows more current to flow through the circuit and allows the voltage to rise. The 103-681FS therefore provides a degree of regulation to circuits subjected to varying temperatures.

Conclusion

The 103-681FS is a medium-sized, radial-lead, fixed-inductor designed primarily for use in a range of electronic applications. It can handle up to 3.5A at a maximum temperature of 85° Celsius and provides excellent protection against EMI. The 103-681FS is suitable for use in industrial, medical, power switching, switch-mode power supply and audio amps applications. Its working principle is based on controlling current or voltage within the 85° Celsius temperature range, by providing an adjustable level of inductance. The 103-681FS is a great choice for many applications.
