HM72B-066R8LFTR13

Fixed Inductors

Fixed inductors, also known as chokes, are passive electrical components typically used to oppose changes in current while providing minimum opposition to the steady-state current flow. They are available in a wide range of form factors, inductance values, and current ratings, making them suitable for a variety of applications. One such inductor is the HM72B-066R8LFTR13, a through-hole inductor with an inductance of 6.8 μH and a rated current of 0.74 A.

Applications

The HM72B-066R8LFTR13 is an ideal choice for various switching power supply, DC/DC converter, and filter circuits. It can be used as a filter choke to reduce the effect of noise and ripple in the electronic circuits. It is useful in various audio applications for avoiding interference with the signal, such as in speaker protection circuits. Other applications include inductors for switching mode power supplies, battery chargers, and energy storage and conversion circuits.

Working Principle

The HM72B-066R8LFTR13 uses the principle of inductance to oppose changes in current flow. When an alternating current (AC) passes through an inductor, it creates an opposing magnetic field which induces a voltage in the opposite direction, thus decreasing the current flow. This property of resistance to current changes is known as inductance. The HM72B-066R8LFTR13 has 6.8 μH of inductance which is usually measured in millihenries (mH).

In the steady-state, the reactance offered by the inductor is relatively low and presents minimum opposition to the current flow. The rated current of the HM72B-066R8LFTR13 is 0.74 A, which means that it can safely handle a current of up to this value without getting damaged. It is important to note that if the current exceeds the rated value, the component can heat up and eventually get damaged due to its self-heating effect.

Conclusion

The HM72B-066R8LFTR13 is a through-hole fixed inductor with 6.8 μH of inductance and a rated current of 0.74 A. It is suitable for use in applications such as switching power supply, DC/DC converter, filter circuits, and audio applications. It uses the principle of inductance to oppose changes in current flow, while presenting minimum opposition to steady-state current. Care should be taken to ensure that the rated current is not exceeded, or else the component may heat up and get damaged.
