Ceramic filters are components used within an electronics system to separate or extract internal and external signals in order to ensure that those signals remain separated in order to produce the desired result. They can be used for various functions—from repairing distorted signals to preventing interference from external sources. CER0405B is a type of ceramic filter used for applications such as suppressing broadband interference on control board and other EMI sensitive devices.
The CER0405B series consists of surface-mountable filters with a wide frequency range from 0.2 MHz to 2.5 GHz. The filters feature a very consistent performance of insertion loss and are also capable of suppressing incoming signals up to 40dB, making them suitable for a variety of EMI-sensitive and noise-reducing applications. CER0405B filters are composed of multiple internal ceramic resonators connected in series and in parallel. These resonators effectively filter out unwanted frequencies and allow the desired frequency to pass through the filter. The resonators are composed of several layers of ceramic which are tuned to specific frequency bands. The most important function of these filters is to block or attenuate signal at certain frequencies. This is done by making use of an attenuator circuit and a resonance circuit inside the filter. The two circuits interact to create a bandstop filter, which is also known as a notch filter.An attenuator circuit works by introducing losses into a signal at specific frequency ranges. The losses are dependant on the design of the attenuator circuit and can range from very small to very big. As a result, the attenuator circuit can greatly reduce the strength of signals passing through it.The second part of the filter is a resonance circuit, which strengthens or amplifies certain frequencies. This is done by using what is known as a resonance frequency, which is a frequency at which the circuit resonates with maximum amplitude. The resonance frequency can be adjusted to filter out noise of various frequencies, thus allowing only the desired signal to pass through.CER0405B filters are designed to provide high performance and excellent RF characteristics for a variety of EMI-sensitive applications such as noise-reducing for control boards. The filters are capable of rejecting unwanted signal up to 40dB while passing through signals with minimal distortion. With their wide frequency range, CER0405B filters can also be used for repairing distorted signals, thereby improving signal quality.
In summary, CER0405B filters are a type of ceramic filter used for EMI-sensitive and noise-reducing applications. The filters consist of a combination of an attenuator circuit and a resonance circuit that work together to block or attenuate certain frequencies. The filters are capable of rejecting unwanted signal up to 40dB, making them suitable for a variety of applications where high performance and excellent RF characteristics are required.
