Fixed inductors are electronic devices that are designed for high current applications and feature a tolerance of ±5%. This particular device – SPD127 – 394M, is a fixed inductor that comprises of 4.0 mΩ maximum DC resistance substrate, a 4.7 mH nominal inductance, and a self-standing construction. Fixed inductors can be used in a multitude of applications, ranging from portable equipment to telecommunications.

The SPD127-394M is a part of the Panasonic’s Shielded Fixed Inductor Series – an excellent range for use in audio-frequency circuits, switching power supplies, electronic ballast and other circuits requiring high current. As such, this particular device features multiple layers of epoxy coating that is able to withstand up to 12W of power dissipation. Also, the inductance of this device can be varied depending on the design requirement, making it exceptionally versatile.

In addition, the SPD127-394M has been designed and tested to meet all safety standards, and has a wide operating temperature range of -40°C to 125°C. This device is RoHS certified and consists of connection leads that are composed of tin plated copper wire. The leads are terminated with 2 pins placed across from each other, allowing for easy connection to almost all types of circuits.

When it comes to the device’s working principle, fixed inductors work by storing electrical energy in a magnetic field generated by a coil. These devices induct electrical current on one side of the coil and then output current on the other end. The current flowing through the inductance is determined by the equation of inductance. Essentially, the inductance is a measure of the opposition to the flow of alternating current through an electrical conductor.

The SPD127-394M is a great fixed inductor with a wide working temperature range, excellent power handling capabilities, and compliance with all safety standards. The device is perfect for use in applications like audio-frequency circuits, switching power supplies, and electronic ballasts.Moreover, because of its two dissipating pins, this particular device is easy to connect to almost any type of circuit.
