About CTS (Tusonix)
CTS Corporation is a global leader in electronic components and sensors, with Tusonix as its specialized EMI/RFI filtration division. For over 50 years, Tusonix has pioneered feed through capacitor technology, setting industry benchmarks for high-frequency noise suppression in mission-critical environments.
Renowned for rigorous MIL-SPEC testing and compliance, CTS components are trusted in aerospace, defense, and medical applications where failure is not an option. Their vertically integrated manufacturing ensures consistent quality and traceability from raw materials to finished products.

About Feed Through Capacitors
Feed through capacitors provide critical EMI/RFI filtering by shunting high-frequency noise to ground while allowing DC or low-frequency signals to pass unimpeded. Unlike standard capacitors, their unique coaxial design minimizes lead inductance, enabling effective noise suppression into the GHz range.
These components are indispensable in applications requiring electromagnetic compatibility (EMC), particularly where signals pass through shielded enclosures. Proper implementation prevents interference in sensitive electronics, meets regulatory standards (FCC/CE), and ensures system reliability in electrically noisy environments like industrial controls or RF transmission systems.
