EMI/RFI Noise Filters
Product Description
Our evolution has paved the way to become the best EMI/RFI noise filters manufacturers in India. Electromagnetic interference (EMI) or radio frequency interference (RFI) prevents the performance of the electrical circuit. Within the power signals, EMI or RFI evolve - meaning they propagate in free space. They cause damage to most of the applications including military devices and hospital machinery. Through one of the four frequency filters – low pass, high pass, band pass, and band stop filters; EMI/RFI noise is rejected.
Considerations
- Insertion loss : A positive gain measurement that defines EMI/RFI filter’s effectiveness in decibels. Majorly, insertion losses are less applied.
- Filtering power lines : Power lines are subdivided into different phases with neutral lines attached.
- Size Considerations : Size and weight are vital aspects if an application has limited space. However, these are available in various sizes but must fit the application.
