Selecting the Right SMD Power Chip or Through-Hole Inductor

What Is SMD Power Chip Inductor? 

SMD power inductors or SMD power chip inductors are small components that store and release energy in a circuit. They are usually found in surface mount technology (SMT) circuits and power supply designs. SMD power chip inductors are composed of individual coils that are etched onto a chip and then coated with a protective material. Due to their small size, they are ideal for circuits with limited board space or where higher component density is desired. They can also be used in applications where EMI/RFI noise suppression is necessary. 

SMD power chip inductors are the most reliable and cost-effective way to implement a power supply circuit. The chip’s surface-mounted design improves power transfer efficiency and reduces the amount of heat generated by the circuit. In addition, the chip’s small size allows it to be easily incorporated into various circuit designs and helps minimize the required board space.

Certain specifications should be kept in mind to ensure that the inductor used is the best choice for the application. These specifications include the inductance value, current carrying capacity, temperature range, and power rating. Additionally, the substrate material used to construct the chip should be considered, as it affects its performance. Generally, the substrate material should dissipate heat effectively and protect the chip from physical damage.


How Does SMD Power Supply Work? 

An SMD power supply circuit comprises several essential components, including an SMD power chip inductor, a capacitor, and a diode. The inductor and capacitor act as a filter to regulate the current supplied to the circuit. The diode protects the circuit from damage due to an excess voltage.

The primary function of a power supply circuit is to step down the voltage from a higher value to a lower one that is suitable for the circuit’s needs. The incoming voltage is first filtered using the inductor and capacitor to achieve this. Next, the filtered signal is pushed through the diode, where the excess voltage is regulated and discharged. Finally, the filtered voltage is sent to the circuit’s load. 

The SMD power chip inductor is crucial in the power supply circuit. The inductor’s coils act as a filter, allowing only the required current to pass through the diode. Additionally, the inductor’s small size allows it to incorporate into tight spaces while efficiently providing effective filtering.
