Helical Filters

Helical filters are a type of filter that uses a helical shape to remove unwanted signals or frequencies from a signal. They are commonly used in radio frequency (RF) and microwave applications, as well as in EMI (electromagnetic interference) optimization in cables. Helical filters are known for their high Q factor, which is a measure of how well the filter can reject unwanted signals. This makes them highly effective at blocking specific frequencies, making them a popular choice for EMI optimization in cables. Helical filters are typically made from metallic materials, such as copper or brass, and can be either surface-mount or through-hole.
