Fixed inductors are components used in electronic circuits to control current and voltage levels. The ER1641-824JP is a type of fixed inductor used in applications such as DC-DC converters and switchmode power supplies. It is part of the E-Series family of inductors and is designed to provide a high inductance range of values from 0.46 to 10.2 mH. The ER1641-824JP features high-quality construction with an industry-standard, thick-film leadless surface-mountable design that offers excellent electrical properties and performance in a wide variety of applications.The ER1641-824JP is designed to offer a wide range of inductance values and overall performance. It is capable of operating over a wide temperature range, from -40°C to +105°C, and is capable of withstanding up to 125% of rated voltage. The inductor is RoHS compliant and is designed to comply with the JIS-C6331 standard.Working PrincipleThe working principle of an inductor lies in the way it stores energy. An inductor is composed of one or more turns of wire wound around a core material, which can be either air, ferrite, or other magnetic material. When a current travels through an inductor, it creates a magnetic field, which in turn generates a magnetic flux, resulting in a voltage drop across it. This voltage drop is the inductor’s inherent reactance, and it increases with increasing frequency.This voltage drop acts as the inductor’s resistance to changes in current. As the current through the inductor increases, the increasing voltage drop across it causes the current flow to slow down or even stop. This is called inductive reactance, and it is the basis for the inductors mathematical formula for inductance. The formula for inductance is based on the coils inner diameter, length of wire, and number of turns.The ER1641-824JP utilizes this principle to offer a wide range of inductance values. Its wide temperature range allows it to operate efficiently and safely in a variety of applications. Its thick-film leadless design also makes it well suited for use in high humidity environments, and its performance is further enhanced by its RoHS compliance.ConclusionThe ER1641-824JP is a type of fixed inductor that is designed to offer a wide range of inductance values and overall performance. It is capable of operating over a wide temperature range and is capable of withstanding up to 125% of rated voltage. Its thick-film leadless surface-mountable design makes it well suited for use in high humidity environments and its RoHS compliance allows it to be used in eco-friendly systems. The ER1641-824JP is a reliable and versatile fixed inductor that is suitable for use in a variety of applications, including DC-DC converters and switchmode power supplies.
