Fixed Inductors and the IHLP4040DZER150M11

Fixed inductors are essential components in both electrical and electronic circuits. They have a variety of applications, ranging from simple snubber circuit components to complex devices used for niche applications. A good example of this is the IHLP4040DZER150M11, a fixed inductor developed by Vishay and released in early 2020.

Application Fields of the IHLP4040DZER150M11

The IHLP4040DZER150M11 is a high-performance, low profile, surface mount inductor developed for use in the personal electronics, industrial, and automotive industries. It is often used in DC/DC converters, snubber networks, and other power supply applications. It is designed to provide maximum PCB real-estate savings while offering excellent performance. It has a wide operating temperature range of -40°C to +125°C, suitable for applications that require reliable performance in extreme environments.

Working Principle of the IHLP4040DZER150M11

The IHLP4040DZER150M11 is an inductor, and as such, it works based on the principle of inductance. When current passes through the device, a magnetic field is generated, and this field induces a voltage across the device. This voltage is generally in the opposite direction from the current, and it is known as the inductance voltage. This voltage is then used in the application to either increase or decrease the amount of current in the circuit.

The IHLP4040DZER150M11 consists of a ferrite core and a surrounding windings of copper wire. The ferrite core is insulated so that the windings are not in contact with it, ensuring that the current does not wire its way through by shorting out the inductor. The windings are arranged in a specific pattern, which is responsible for the output voltage of the inductor.

The IHLP4040DZER150M11 has a very high inductance-voltage ratio, which means that it can provide a voltage spike up to 200V at a relatively low induced current. This makes it suitable for applications that require a high voltage but low current, such as in snubbers. In addition, the inductor has a very low series resistance and high inductance stability, making it ideal for complex, high-frequency operations.

Conclusion

The IHLP4040DZER150M11 is a high-performance fixed inductor from Vishay. It is designed to be used in power supply and snubber circuit applications where a compact, low profile form factor and high-performance levels are necessary. Its excellent inductance stability and low series resistance make it ideal for a wide range of applications. It is a highly efficient and reliable solution for industries such as personal electronics, industrial, and automotive.
