Fixed Inductors are components designed to store energy in the form of a magnetic field in a coil of wire. The ER1641-394JM is a smd surface mount inductor that is wound with a ferrite core and is an ideal choice for power supply applications. It has a rated inductance of 4.7μH and a rated current of 2.2A making it ideal for DC to DC converters and power supply applications. The ER1641-394JM has a fairly low DCR of only 0.12Ω and a very low AC resistance of 0.003Ω meaning that it can provide maximum current without significant voltage drop.The ER1641-394JM is a surface mount inductor that is rectangular in shape with dimensions of 16.5mm x 8mm x 7mm. It is designed to be mounted on a PCB board and is RoHS compliant. It has a UL94 V-2 rated insulation which means that it is safe to use in a wide range of applications.The working principle of the ER1641-394JM is based on the principle of electromagnetic induction. When current is passed through the coil, it generates a magnetic field. This magnetic field then induces an electric current in the coil, which is then stored as energy in the form of a magnetic field. When the current is removed, the energy stored is released back in the form of an electric current, which is then used to power the device.The ER1641-394JM is a highly efficient inductor which makes it ideal for use in DC to DC converters, power supplies, and other high current applications. It is also commonly used in DC motor control circuits as it is able to handle high currents without significant losses. As it is small and lightweight it can also be used in space-constrained applications such as mobile phones and tablet computers.The ER1641-394JM can be used for a wide range of applications due to its high efficiency and reliability. It is particularly useful in applications which require high current at low voltage and is often used in switching power converters, personal computer motherboards and DC motor control circuits. Due to its relatively low DCR, it is also often used to reduce power losses in power supply circuits.In conclusion, the ER1641-394JM is an ideal choice for power supply applications and other high current applications. Its compact size and low DCR make it well suited for applications which require high current and low voltage. It is RoHS compliant and has excellent performance characteristics making it suitable for a wide range of applications.
