Fixed Inductors are electrical components used to introduce inductance into an electrical circuit. They are commonly used in analog circuits to filter frequencies, adjust signal levels, store energy, regulate current, or for many other purposes. The 1210-271J model is a type of fixed inductor, designed to provide a large inductance rating in a small package. This article will discuss the specific application field and working principle of the 1210-271J.

1210-271J Application Field

As a fixed inductor, the 1210-271J has a wide range of potential applications, primarily related to filtering and signal handling. It can be used in a variety of analog circuits, such as low-noise amplifiers, frequency synthesizers, signal pre-amplifiers, pulse detection circuits, power converters and switching regulators.

The 1210-271J is also suitable for automotive applications, including but not limited to motor control, anti-lock-braking systems, ignition systems and emission control. Its robust construction and excellent operating temperature range makes it suitable for use in harsh environments or in applications where temperature-related stability is a concern.

In addition, the 1210-271J can be used for power supply circuits, signal processing and digital-to-analog conversion systems where EMI (electromagnetic interference) suppression is required.

1210-271J Working Principle

An inductor works by opposing changes in the current flowing through it. Whenever there is a change in the current, a magnetic field is created. This magnetic field then generates a back EMF (electromotive force) which opposes the original change in current. The back EMF is measured as the inductance of the inductor, and the amount of current which an inductor is able to resist is determined by this inductance.

The 1210-271J is designed to provide a large inductance rating in a small package. It consists of a steel core wrapped in copper wire, with an epoxy resin coating for extra protection. The inductance is determined by the dimensions of the core and the amount of wire coil on it.

The 1210-271J has been tested to operate up to 100MHz, with an operating temperature range of -40 to +105°C. It is rated for an inductance of 10.7μH to 13.7μH (depending on the core material and wire length), a saturation current of 6.2A (typical) and a DC resistance of 0.7Ω maximum. It is also rated for a maximum direct current of 0.25A.

Conclusion

The 1210-271J is a fixed inductor designed to provide a large inductance rating in a small package. It is suitable for a wide range of applications, including automotive, signal processing, EMI suppression and power supply circuits. Its working principle is based on the magnetic field generated when current passes through a steel core wrapped in copper wire. The 1210-271J is rated for an inductance of 10.7μH to 13.7μH, a saturation current of 6.2A (typical) and a DC resistance of 0.7Ω maximum.
