Fixed inductors are electronic components that store energy in the form of an electric field or magnetic field. Specifically, inductors are made up of a coil of wire that is wound onto a core material such as metal, ferrite, or even air. The current flowing through the inductor creates a magnetic field around it, which is proportional to the number of turns in the coil. Inductors are commonly used in radio frequency applications to filter out unwanted or interfering signals.

PA1894.191NL Application Field and Working Principle

The PA1894.191NL is a surface-mount inductor that is part of the PA1894 series of high-frequency fixed inductors. This fixed inductor consists of a ferrite core, with a copper coil wrapped around it, which is encased in a plastic, or less commonly, an epoxy package. The device is designed to operate at frequencies from 4.0 MHz to 10 MHz, and has an operating temperature range of -40 to +85 °C. The inductance range is from 120nH to 470nH, with an ±5% tolerance. It has a leakage inductance of less than 7nH, and a dcr (DC resistance) range of 6.9 mOhm to 24 mOhm.

The PA1894.191NL is very useful in the field of radio frequency and communications. It can be used for power supplies, DC-DC converters, EMI (electromagnetic interference) filtering, RF (radio frequency) communication circuits, DC-DC converters, and many other applications. It offers superior performance in high-frequency applications, with high Q factors, low leakage inductance, and low DCR values. The inductor also uses surface-mount technology, which allows for a smaller form-factor package, and better performance in high speed digital applications.

In general, the working principle of a fixed inductor is based on the law of induction. This law states that if a conductor is carrying a current, it will create a magnetic field around it. The strength of this magnetic field is proportional to the amount of current flowing through the inductor, and the number of turns of the coil. When AC current is applied to the inductor, the magnetic field oscillates, inducing an electromotive-force in the coil, which opposes the applied voltage from the source. This opposition to current flow is what is known as inductance.

The PA1894.191NL is an ideal choice for those applications that require a higher inductance, low leakage inductance, and superior performance in high frequency applications. The high Q factor and low DCR make the inductor suitable for RF circuits, power supplies and other circuits that require EMI or RFI filtering. The ability of the device to withstand higher temperatures allows it to be used in a variety of applications. The PA1894.191NL is a reliable and high quality product that can be used in various applications that require higher inductance and better performance.
