Ferrite Beads and Chips: EXC-ELDR35V Application Field and Working Principle

The EXC-ELDR35V is a type of ferrite beads and chips that has a wide range of applications in different industry sectors. It is a high-precision, low-cost, non-inductive and high-frequency ceramic chip inductor designed for pulse current applications such as CPU power management, LCD panel display current control, IGBT/MOSFET gates driving, and EMI/EMC immunity applications. The EXC-ELDR35V is available in three size variations: 3.2*1.6mm, 5.0*2.5mm, and 7.5*3.2mm, and is available in two rated current values: 1.7A and 2.5A.

Construction and Design

The EXC-ELDR35V is constructed from a two-layer design with a ceramic substrate bonded between two metal layers. The substrate is composed of a high temperature, non-inductive, high-energy ceramic material, while the two metal layers are composed of silver or copper with no lead for improved reliability. The chip inductor has two internal leads embedded in the ceramic substrate, making it ideal for electronic circuit board space savings.

Working Principle

The EXC-ELDR35V works using an inductor-type principle, where the inductor creates a magnetic field around it that constricts and expands the flow of current through it. When a current is passed through the chip, the magnetic field produced by the inductor constricts the flow of current, slowing it down and reducing its amplitude. As the current exits the chip, the magnetic field in the inductor expands, allowing the current to flow freely again. This factor reduces the ripple and noise created by high-speed switching applications.

Applications

The EXC-ELDR35V chip inductor can be used in many applications, such as pulse current control, general power management systems, switching power supplies, IGBT/MOSFET gates driving, and EMI/EMC immunity. The EXC-ELDR35V’s small size and light weight make it ideal for space-constrained electronic components designs and light weight power supplies. It can also be used to reduce EMI/RFI noise from electronic circuits, as its small size allows for effective shielding against unwanted noise and interference.

Conclusion

The EXC-ELDR35V chip inductor is a high-precision, low-cost, non-inductive, and high-frequency ceramic component designed for use in pulse current applications. It is available in three size variations and two current values, and can be used to provides space savings, reduce EMI/RFI noise, and improve the performance of power management systems, switching power supplies, IGBT/MOSFET gates driving, and EMI/EMC immunity applications.
