Introduction

This article aims to provide a comprehensive overview of the ER1641-223JP fixed inductor. It is categorized under "Fixed Inductors" due to its ability to provide a constant inductance. The article explains the working principle and application field of the ER1641-223JP.

What Is a Fixed Inductor?

A fixed inductor is an electronic device that functions by limiting the flow of current across an electric circuit. It consists of a wire wound around a core and its purpose is to store energy in the form of a magnetic field. Conceptually, the inductor acts as an opposition to changes in current. This resistance to the changes in current cause a voltage, known as inductive reactance, to be generated that is a function of the frequency and inductance of the inductor. Thus, an inductor is primarily used to reduce the current in an electric circuit and can be used in combination with other components to form complex circuits.

ER1641-223JP: Description and Specifications

The ER1641-223JP fixed inductor is a type of generic surface-mount inductor. It is made from high-efficiency ferrite material and consists of a capacitor, resistor, and inductor (L1).The ideal inductance value of the ER1641-223JP inductor is stated as between 220 to 224μH and its DCI (direct current impedance) between 1.5 to 1.6ohms. The inductor core is made of powdered iron and its packaging is constructed with a thin thermal epoxy. The inductor can also withstand operating temperatures between -55°C and +125°C without compromising its operation.

ER1641-223JP: Working Principle

The ER1641-223JP works by limiting current flow across an electrical circuit. To achieve this, it relies on the formula: voltage = current * inductance. In this way, the voltage generated by the inductor can be used to limit current flow in the circuit.
