Fixed Inductors

Fixed inductors are electronic components typically composed of wire coils and ferrite cores. They are mainly used to store energy and provide a steady current flow. These inductors also possess the ability to reduce radio frequency interference (RFI) and electromagnetic interference (EMI). This makes them ideal components for use in applications where a stable and consistent electrical current is required.

103-181JS Application Field

The 103-181JS series fixed inductors are designed for applications in the AC/DC power supplies, DC/DC power converters, battery powered and automotive electronics, telecommunications, audio-visual equipment, industrial motors, and digital home appliances. Additionally, they can be used as input and output filters for power supplies, and as EMC filters. The 103-181JS line has a max operating frequency of 400 kHz and a wide range of inductance values from 2.2 (uH) to 220 (uH). They are also rated for voltage values of 0.35 to 10 VDC.

Working Principle of the 103-181JS Inductor

The 103-181JS inductors employ a basic working principle of generating a steady electrical current from a varying voltage source. This is done by winding multiple coils around a ferrite core which is composed of two slabs of ferrite material with an internal air gap. The alternating current provided by the voltage source produces a fluctuating magnetic field which induces a current in the coils. The resulting magnetic field produced by the current flow within the inductor\'s coils opposes the change in current and stabilizes the voltage source.

The main function of an inductor is to store energy. The energy stored within an inductor is proportional to the inductor\'s inductance, expressed in millihenries (mH). As the current increases, the magnetic field and inductance within the device also increases. This causes a build up of energy which is released as a steady current after the voltage source is stopped. This makes inductors useful in applications requiring steady current flow.

Benefits of the 103-181JS Series Inductors

The 103-181JS line of inductors offer many advantages over their competitors. These include higher operating frequencies, wide range of inductance values, and current-compensated designs for improved reliability. The inductors also offer low-profile surface-mount designs with tape-and-reel packaging to improve board density and assembly cycles. Additionally, between 250 to 8,000 pieces can be supplied on the same reel. This makes the 103-181JS series perfect for applications which require a high level of component count.

Conclusion

The 103-181JS series of fixed inductors offer stable electrical current and energy storage capabilities thanks to their wound magnetic wire coils and ferrite core design. They are used in wide variety of applications such as AC/DC power supplies, DC/DC power converters, and automotive electronics. The components offer higher operating frequencies, wide range of inductance values, and low-profile surface-mount designs with tape-and-reel packaging for improved board density and assembly cycles. This makes the 103-181JS series the perfect choice for applications requiring steady electrical current and energy storage.
