The LCA® Resin Sealed EMI Filters Series caters to EMC protection needs across multiple fields, delivering highly reliable filtering solutions for equipment in diverse scenarios with both excellent adaptability and stability. Whether used as EMI filters for medical devices or industrial automation equipment, it provides long-term EMC protection, serving as a core supporting component for electromagnetic compatibility of equipment in various applications.
LCA Thread Mount Feedthrough Filters are designed to suppress conducted electromagnetic interference (EMI) and radio frequency interference (RFI) while allowing DC and low-frequency signals to pass with minimal loss. Featuring a threaded metal housing with epoxy sealing, they provide reliable grounding, effective shielding, and stable electrical performance for industrial and commercial electronic systems.
Compared with conventional filtering solutions, the threaded metal housing creates a continuous connection with the equipment enclosure, reducing EMI leakage around panel entry points and improving overall electromagnetic compatibility (EMC).
This model features a 4700pF capacitance, 50VDC rated voltage, and a C circuit configuration with an M6 threaded mount for secure installation and dependable grounding. It is ideal for applications requiring a compact, cost-effective EMI filtering solution.
LCA also offers customization of capacitance, voltage rating, thread size, terminal style, and other electrical or mechanical specifications to meet OEM and project-specific requirements.

✔ RoHS Compliant Materials
Manufactured using environmentally compliant materials in accordance with applicable RoHS requirements.
Industrial Automation
Industrial control systems frequently operate in electrically noisy environments generated by motors, variable frequency drives, relays and switching power supplies. Thread Mount Feedthrough Filters help prevent conducted interference from entering sensitive control circuits, improving the stability and reliability of PLCs, servo systems, industrial robots, CNC equipment and automated production lines.
Medical Equipment
Medical electronic equipment requires extremely stable electromagnetic performance to ensure accurate diagnosis and reliable operation. These filters are commonly integrated into diagnostic instruments, patient monitoring systems, laboratory analyzers and medical power supplies to reduce conducted EMI and improve overall system reliability.
Telecommunications
Communication equipment demands clean power and stable signal transmission. Thread Mount Feedthrough Filters help suppress unwanted conducted noise in communication base stations, network infrastructure, RF equipment and data transmission systems, contributing to improved signal integrity and reduced electromagnetic interference.
Power Electronics
Switching power supplies, DC-DC converters, inverters and battery management systems generate high-frequency conducted noise during normal operation. Feedthrough Filters provide effective suppression at enclosure entry points, helping improve EMC compliance and reduce system emissions.

LCA manufactures high-performance EMI/RFI filtering components using precision machining and carefully selected materials. Continuous process control and production optimization ensure consistent quality while supporting both standard products and customized OEM solutions.
Thread Mount Feedthrough Filters require minimal maintenance under normal operating conditions. However, periodic inspection of mechanical mounting, grounding continuity and environmental conditions is recommended during routine equipment maintenance.
Avoid excessive mechanical stress, impact or contamination that may affect long-term electrical performance. When replacing a filter, ensure the replacement specification matches the original electrical and mechanical requirements.
A Thread Mount Feedthrough Filter is a passive EMI suppression component installed directly through a conductive enclosure wall. It suppresses conducted electromagnetic interference while allowing useful electrical signals or power to pass through with minimal loss.
C circuits are suitable for general applications, while LC, Pi and T configurations provide progressively improved filtering performance for more demanding EMI environments.
Standard UNF and metric thread sizes are available. Custom thread dimensions can also be manufactured according to customer requirements.
Yes. LCA offers customization of capacitance, voltage rating, thread size, circuit configuration, housing dimensions, terminal style and surface finish.
Typical applications include industrial automation, medical electronics, telecommunications, transportation systems, instrumentation, power electronics and commercial electronic equipment.
Standard epoxy sealed products are intended for general industrial environments. Applications involving moisture ingress, pressure differentials or harsh environmental exposure should consider hermetically sealed versions.
Hermetically sealed feedthrough filters are recommended when the application requires gas-tight sealing, vacuum integrity, moisture resistance or operation in harsh environmental conditions. Standard epoxy sealed products are generally suitable for most industrial and commercial electronic equipment.
