The LCA® Threaded Feedthrough Capacitor Series responds to EMC protection demands across multiple fields with customized solutions. It offers customizable EMI filters for instrumentation, automotive electronics, and other applications. Based on diverse scenarios, LCA provides tailored EMI solutions and ensures rapid delivery of EMI filters, delivering long-term and precise EMC protection for such equipment.
Hermetically sealed thread mount feedthrough filters are high-performance EMI/RFI suppression components designed for applications where environmental sealing and long-term electrical stability are critical.
Unlike epoxy-sealed feedthrough filters, hermetic versions utilize a glass-to-metal sealing structure, ensuring exceptional resistance to moisture, pressure, vibration, and extreme environmental conditions.
This product family is widely used in aerospace systems, military communication equipment, radar systems, medical imaging devices, and other mission-critical electronics where failure is not an option.
LCA hermetic feedthrough filters are engineered to provide:
✔ Stable electrical performance over long service life
✔ Excellent insertion loss across wide frequency ranges
✔ Reliable EMI suppression in harsh environments
This model features a 1.4uF*2 capacitance, 300 VDC rated voltage, a PI-type circuit configuration, and an 5/16-24 UNF-2A threaded mounting base with glass seals on both ends. It is ideally suited for applications requiring hermetic electromagnetic interference filtering solutions.
✔ Hermetic glass-to-metal sealing for maximum environmental protection
✔ High reliability for mission-critical applications
✔ Excellent EMI/RFI suppression performance
✔ Stable electrical characteristics over time
✔ Thread mount design for secure mechanical installation
✔ Compatible with harsh vibration and thermal cycling environments
✔ Custom circuit configurations available (C / L / LC / Pi / T)
Hermetic feedthrough filters operate by integrating capacitive and/or inductive elements within a sealed conductive housing.
The glass-to-metal sealing ensures that the internal filtering structure is completely isolated from external environmental influences, maintaining stable impedance characteristics over time.
Key mechanism:
Selecting the appropriate Thread Mount Feedthrough Filter depends on several electrical and mechanical factors, including capacitance value, rated voltage, circuit configuration, thread size and operating environment. Understanding these parameters helps engineers achieve optimum EMI suppression while maintaining reliable long-term system performance. READ MORE
