Fixed Inductors

Inductors are passive two-terminal electrical components that store energy in a magnetic field when electrical current flows through it. When the current flowing through an inductor changes, the electromagnetism created by the coils generates a proportional voltage (electromagnetic induction), whose polarity is determined by Lenz\'s law (opposes the current\'s change). Fixed inductors, also referred to as bobbins or coils, are inductors with an inductance that do not change with applied voltage or current. Fixed inductors are used in a wide variety of applications ranging from signal processing to power delivery.

The PT100R-1100HM is a fixed inductor with a measured inductance of 100uH, making it one of the most commonly used fixed inductors. The inductor comes in a molded, RoHS-compliant, sealed package that is suitable for automated assembly. The PT100R-1100HM is commonly used in applications such as DSL modems, Wi-Fi routers, automotive electronics, medical electronics, and power supplies.

Working Principle

The PT100R-1100HM works on the principle of mutual induction, a phenomenon in which a changing magnetic field within one inductor induces a voltage in another nearby inductor. This phenomenon can be explained mathematically by Faraday\'s law of induction, which states that the voltage induced in a coil is proportional to the rate of change of the flux linkage, which is the sum of the magnetic flux through each of the inductor\'s turns.

The PT100R-1100HM follows the standard form of Faraday\'s law by generating a voltage proportional to the rate of change of the applied current, as long as the current and number of turns of the coil remain constant. This voltage is then typically used to either power a load or to provide further signal processing.

Applications

The PT100R-1100HM is primarily used in applications requiring the reliable generation of a constant voltage or current. Its low internal resistance and stable performance make it ideal for use in power supplies, motor controllers, and other electronic devices requiring a steady supply of power. It is also used in signal processing applications because its low-profile design and high frequency response allow it to accurately and quickly process large amounts of data.

The PT100R-1100HM is also well-suited for use in automotive electronics. Its shielded design reduces interference, allowing it to provide clean and accurate data for in-dash displays and other automotive electronics. The PT100R-1100HM is often used in conjunction with other inductors to form a shielded chamber for additional noise reduction. This makes it an ideal choice for automotive RADAR and satellite communications systems.

The PT100R-1100HM is one of the most versatile fixed inductors and is used in a wide variety of applications. Its low-profile design, high frequency response, and shielded design make it well-suited for both high-power and signal processing applications. Its low internal resistance ensures that it can be used with confidence in automotive and medical electronics. With its ability to generate a constant voltage or current, the PT100R-1100HM is a reliable and cost-effective choice for many applications.
