Fixed Inductors

Fixed inductors, also known as chokes, coils and filters, are widely used for power and communications device designs to perform various tasks such as storing energy, filtering, and providing DC bias. Common types of fixed inductors are air-core, ferrite-core, and powdered iron-core.

The LHL13TB682J fixed inductor is a type of air-core fixed inductor. The inductor is made of an aluminum alloy case with an epoxy-based resin bobbin and a ferrite-cored core material. It has a current rating of 4A and a nominal inductance of 8Ω. The inductor has a tolerance of ±10%. The maximum temperature rating is +85°C.

The main purpose of a fixed inductor is to provide inductance to a circuit. Its functionality is similar to that of a resistor, but it works differently. An inductor increases in inductance when a voltage is applied across its ends, meaning that the electrons must absorb energy to be forced into circulation. The absorbed energy is converted into magnetic energy when the electrons circulate in the inductor. As the current changes, the magnetic field changes, and the inductance of the inductor also changes.

The LHL13TB682J fixed inductor is often used for power supply, EMI-EMC filtering, and common-mode filtering applications. Its use in power supply applications helps reduce high voltage spikes and helps keep the power supply stable. In EMI-EMC filtering applications, it works to reduce noise interference in circuit signals. In common-mode filtering applications, it helps minimize the amount of electromagnetic interference in circuits.

Overall, the LHL13TB682J fixed inductor is a reliable and versatile component for various applications that require inductance. Its robust construction and high temperature rating make it suitable for various environments. It is a key component of power supplies, EMI-EMC filtering, and common-mode filtering applications.
