Solder-in & Press-in Feedthrough Filters

CTS miniature EMI ceramic filters and capacitors are designed to suppress unwanted EMI in applications where small size is critical. CTS filters cover a variety of voltage, attenuation, and capacitance ranges in both solder and bushing mount styles. We have QPL approvals to MIL-15733. Popular applications include telecommunication, CATV, telemetry, radar, amplifiers, RF switches and industrial process control equipment.

Thread Mount Feedthrough Filters

The CTS threaded bushing feed-throughs is one of the broadest in the industry and offers a wide range of rejection options supporting Pi-Type, L-Type, and C-Type filter feed-thrus providing 5pF to 1.4µF, support for up to 1000Vdc working voltages, up to 25A of current, and able to provide up to 70dB of rejection at 100MHz and 1GHz.

Surface Mount Filters

The CTS 4700 Series Pi Filters are used where cost and space savings have priority and improved insertion loss is required. The filter's unique design makes it suitable for common production soldering processes. The CTS state-of-the-art manufacturing process results in excellent electrical and mechanical performance. The square or round body allows easy handling, positioning and soldering onto the PCB.

Filter Assemblies

The CTS line of filtered assembly plates provides ease of installation and line customization of standard-size plates. Filter plates are an efficient and cost-effective solution for filtering multiple lines into or between different system compartments.

For higher frequency applications (<50 MHz), filter plates can be more effective than typical surface mount solutions. The inherent shielding characteristics of these plates create an effective RF barrier offering excellent insertion loss and isolation for frequencies greater than 5 MHz. The preassembled plates, which are 100% tested for critical parameters, greatly reduce the time and resources required to install solder mount filters individually. The Quick Connect Series of Filter Plates features a base plate with built-in installation clips. These clips allow for cost effective mounting into the system bulkhead without the cost associated with traditional hardware.

Filtered Terminal Blocks

CTS filtered terminal blocks are specifically designed to save time and money for EMI Filtering applications. By combining a filtering component with an industry-standard terminal block, CTS has created an effective barrier to EMI noise. The CTS filtered terminal blocks allow the engineer to eliminate EMI using an existing mechanical design element combined with the excellent performance of a pi filter. The CTS commitment to excellence and service allows for customization of the filtered terminal blocks to meet your specific EMC qualifications. Backed by more than 60 years of ceramic component production experience, CTS filtered terminal blocks can meet your demanding requirements.
