EMI/RFI filters, particularly LC, RC networks, are essential for high performing electronic systems. The goal of such filters is to attenuate interfering electromagnetic signals that could affect the circuitry. The ELK-EA100FA is a high-performance filter designed for use in a variety of applications. This article examines the application field and working principle of this filter.

The ELK-EA100FA is a filter designed for use in a variety of power output applications. This includes power converter designs, engine control systems, servo drives and other such motor control applications. The filter is ideal for the majority of power line applications and features excellent performance characteristics. It is among the best performing power filters in its class. It offers –3 dB insertion loss, –30 dB common mode rejection, –18 dB differential mode rejection and –25 dB harmonic suppresion.

The ELK-EA100FA is based on a high quality RC network design. It features an array of surge suppressors in its design for high frequency attenuation. At the heart of the filter is a multiple series capacitor arrangement which provides robust, reliable filtering even under harsh conditions. The design also features built-in surge protection, EMI shielding and robust connection points. All such design features contribute to excellent performance and reliability.

The filter operates on the principle of rejecting the frequencies of spurious signals. This is done by using capacitors and inductors in a series-series or parallel-parallel configuration. The combinations of various components in series or in parallel cause the unwanted signals to be rejected, while allowing the desired signals to pass. This is due to the differences in frequencies of the unwanted and desired signals. As a result, the filter is able to attenuate very well-defined frequency bands.

In addition to the RC filters, the ELK-EA100FA also utilizes a series of EMI/RFI suppressors. These suppressors work on the principle of trapping high frequency spurious signals. They absorb stray emissions and act to reduce the intensity of wide-band interference. The EMI/RFI filter also features EMI shielding which can aid in protecting circuit boards against RF interference.

The high performance of the ELK-EA100FA can be attributed to its quality design and high quality components. The combination of EMI/RFI suppression devices, RC network filters and EMI shielding are all contributing factors in making the filter highly reliable and effective.

In conclusion, the ELK-EA100FA is a high performance filter specifically designed for powering output applications. The filter features a robust design based on high quality RC networks with multiple surge suppressors, as well as EMI/RFI suppression and shielding. It is capable of providing excellent filtering performance and is suitable for a variety of power line applications.
