Fixed InductorsFixed inductors are widely used in various electronic circuits, such as audio signal amplification circuits, AC power supply and DC power supply circuits, etc. Among them, 4470R-35J is a typical inductor for application fields and working principle.4470R-35J is a type of fixed inductor providing an AC current signal with a range of 2.5~35 μH. The inductance tolerance of this component is ±20%, and the rated temperature range is at -40°C to +125°C. This fixed iron core inductor is mainly used in various model railway decoder and switching power supply applications.The 4470R-35J features a ferrite core and electromagnetic coils. The ferrite core has less hysteresis loss, low eddy current loss, low dissipation factor, and higher saturation induction. This enables it to operate under larger current flows and maintains a stable inductance. The steady electromagnetic coils convert electric energy into magnetic energy, and the resulting inductance depends on the shape, size and structure of the coils itself.The working principle of the 4470R-35J is quite simple, its core and coils generate an inductor when a current passes through the component, and the electromagnetic field induced by the current produces a counterforce, thus creating an induced voltage working in opposite direction, which prevents the current from changing over time. This process is known as the "Electromagnetic Induction Principle”.In addition, 4470R-35J also features low power loss, good insulation performance, stable parameters, high operating frequency range and high EMC performance. These features make it ideal for model railway decoder and switching power supply applications.In conclusion, 4470R-35J is a type of fixed inductor, with advantages of ferrite core and cold rolled silicon steelcore, low power loss, good insulation performance, stable parameters, high operating frequency range and high EMC performance, making it ideal for applications such as model railway decoder and switching power supply.
