Fixed inductors are electric components, sometimes referred to as chokes or coils, that possess an inductance which does not vary with current or frequency. Inductors store energy in the form of a magnetic field which produces a voltage over the component when the current through it changes. Inductors have a wide range of applications, such as radio frequency, power electronics, and audio. One common type of fixed inductor is the 2534R-26J.

2534R-26J Application Field

The 2534R-26J is a leaded, radial-leaded type fixed inductor. It has an inductance value of 4.7mH within a tolerance of ±5%, a saturation current of 3.2A, an unloaded Q value of 50, and a maximum DC resistance of 0.055Ω. The 2534R-26J is typically used in AC/DC power circuits, DC-DC converter circuits, DC superposition circuits, and power supply circuits. It has an operating temperature range of -40 to +125°C, making it ideal for use in automotive electronics.

2534R-26J Working Principle

The 2534R-26J is an axial-leaded, fixed inductor with a closed shielded structure. It utilizes ferrite material to provide high inductance and minimal direct current (DC) resistance. The main components are a laminated flat ferrite core, a PVC tape for insulation, and two terminations of electrical current. As current is applied to the inductor\'s terminals, a magnetic field is generated around the core, which induces a voltage across it. This voltage is dependent on the inductance of the core and the rate of change of the current. As the voltage increases, so does the magnetic field, causing a decrease in the voltage, which creates a damping effect on the current.

The 2534R-26J has a high efficiency over its full temperature range, maintaining a constant impedance even when the ambient temperature is high or when the current is heavily loaded. Low noise and ripple values are also maintained by the design and the use of coated/shielded copper wires. The 2534R-26J is also noted for its exceptionally low temperature coefficient, meaning its inductance is stable even with varying temperatures. This stability allows the 2534R-26J to be used in a wide variety of applications, from automotive to audio.

Conclusion

The 2534R-26J fixed inductor is a versatile component for a wide range of applications. It has a high efficiency over its full temperature range, low noise and ripple values, and an exceptionally low temperature coefficient, which gives it stability and reliability. With its wide variety of uses, the 2534R-26J is an ideal choice for AC/DC power circuits, DC-DC converter circuits, DC superposition circuits, and power supply circuits.
