Fixed Inductors

Inductors or coils are components that oppose the changes in current. Fixed inductors are used in general-purpose applications and industrial automation. An example of a fixed inductor is the IR02EV101K.

IR02EV101K Application Field and Working Principle

The IR02EV101K is suitable for use on printed circuit boards in power supplies, battery chargers and adapters, LED dimmers, power Factor Correction (PFC), controllable speed drives, and motor cycle ignitions. The IR02EV101K also has a low EMI and transient energy radiation, making it suitable for switching power supplies and charger applications.

The IR02EV101K is the preferred type when large inductance for low-power consumption is required. Its spiral construction allows higher values of inductance with tightly controlled tolerance of the inductance produced. This makes it suitable for narrow bandwidths LED lamp dimmers, LED PWM dimmers, and junction box dimmers.

The primary working principle of the IR02EV101K is based on the interactions between the magnetic field of the coil and the current in the wire. The coil is energized when the current enters each winding and exits the opposite end. This current creates a magnetic flux which induces a voltage in the coil and causes the current to continue around the core to complete the circuit.

The inductance of the IR02EV101K is determined by the number of turns of the coil, the core size, and the material of the core. It also incorporates an inherent self-protection by its high impedance when excited. This makes it suitable for rectifier circuits, voltage clamp circuits, and resonant circuits.

The IR02EV101K also features a spiral construction which allows higher values of inductance with tightly controlled tolerance. It has a closed magnetic field which eliminates the effects of external static fields and makes it suitable for use with sensitive electronic components. The low profile of the device also facilitates design-in ease in tight spaces.

In summary, the IR02EV101K is a fixed inductor which has various applications. It has a relatively low profile, and its spiral construction makes it suitable for higher values of inductance with tight tolerances. The low profile of the device also makes it suitable for use in tight spaces. Its primary working principle is based on magnetic flux and current in the wire.
