Introduction to Fixed Inductors

Fixed inductors, as the name suggests, are components with a fixed inductance value. These devices often assume the form of chips, and they are particularly useful components in filters. Like resistors and capacitors, fixed inductors are passive components -- they store energy in the form of a magnetic field rather than electrical energy as capacitors do.Fixed inductors are generally categorized in the same way as other components; they come in varying sizes, values, tolerance ranges, and temperature coefficients depending on their purpose. One of the most important characteristics of these devices, though, is their self-resonant frequency, which is the frequency at which the reactance of the device in a given circuit reaches a minimum. Due to the fact that these devices are often used in high-frequency filters, having a low self-resonant frequency is important for maintaining signal purity witin a given frequency range.

IM04EB100J Application Field and Working Principle

The IM04EB100J is a fixed inductor produced by Panasonic Corporation. This device is a 4-pin, 0805-sized chip that is classified as a low profile, high-current inductor. It operates within a temperature range of -40°C to +125°C, and it features an inductance tolerance of ±20%. As the inductance value of this device is 100µH, its self-resonant frequency is 5MHz.The primary purpose of the IM04EB100J is to provide efficient energy filtering in place of the ubiquitous and reliable electrolytic capacitor. This helps reduce the size of the device and improves the efficiency of the captured energy, thus reducing power loss. In addition, this device has a better tolerance towards high-frequency interference than do traditional electrolytic capacitors.The IM04EB100J is designed to store energy in a magnetic field and release it when electrical current passes through the inductor. When an AC current passes across the inductor, the alternating magnetic field that is produced induces a current in the opposite direction. In the case of the IM04EB100J, this current is limited to 100mA due to its maximum current rating. It\'s important to note, however, that as the frequency of the applied current increases, the inductance of the device decreases; this makes the self-resonant frequency an important factor to consider.

Conclusion

The IM04EB100J is a high-current, low-profile fixed inductor that is produced by Panasonic Corporation. This device is a highly efficient component that is well suited for filtering high-frequency currents. It has an inductance of 100µH and a self-resonant frequency of 5MHz. The IM04EB100J is a great alternative to electrolytic capacitors, and it is useful for reducing size and improving efficiency.
