Fixed Inductors

Fixed inductors, also known as coil,reactor or choke, are used in electrical circuits to store and release energy in the form of a magnetic field.The ER1641-474JR is a fixed inductor which falls under those subset of inductors.

Application Field and Working Principle

The ER1641-474JR is used in a variety of applications, such as measuring and filtering circuits.It operates on a basic principle of releasing energy in the form of a magnetic field when a current is passed through it. It is capable of being used to reduce harmonic distortion in lighting circuits and other heavily loaded applications.

The main features of the ER1641-474JR are that it has a low DC resistance and is able to handle both alternating and direct current. This type of inductor is particularly suitable for applications involving currents of up to 3 A.The inductance value of the device is 74 nH and the tolerance is ±10%.

The performance of the ER1641-474JR depends on the circuit design, the temperature of the inductor, as well as the frequency of the current passing through it. When the operating temperature is higher than the specified temperature, the inductance decreases as the operating temperature increases. The inductor is not recommended to be operated at temperatures exceeding 125ºC.

The ER1641-474JR is a RoHS compliant device which is constructed in a lead free epoxy case with a tinned copper winding.The lead spacing of this device is 4.5mm. It has a rated current of 3 A and a rated voltage of 165 V DC.The fairly low impedance of this device makes it suitable for use in a variety of circuits.

The ER1641-474JR is a popular device for many applications, due to its ability to maintain a consistent inductance over a wide range of temperatures and frequencies. This makes it an ideal choice for use in measuring, filtering and suppression applications.
