LIANLINK filtered D-Sub connector LIANLINK  combines standard D-Sub components with a filter element positioned between each contact and the ground shell. These connectors are designed to **maintain signal integrity** and provide **EMC protection** in critical applications, ensuring the proper functioning of electrical devices and systems³. Here are some key details about filtered D-Sub connectors:

1. **High Performance Filtered D-Sub Connector (Series 700)**:

   - Available in shell sizes from 9 to 50.

   - Various termination types, including PC mount, wire wrap, solder cup, and 90° PCB.

   - Filtering options: Pi filter configuration (45-60 dB per decade slope to insertion loss curve) and capacitive-only C filters (cost-effective EMI attenuation).

   - Applications: commercial aerospace, military, medical electronics, industrial equipment, and more.

   - RoHS compliant with exemption 7¹.

2. **High Density Filtered D-Sub Connector (Series 600)**:

   - Designed to MIL-C-24308 specifications.

   - Capacitance values range from 80 pF to 4000 pF.

   - Available in feedthrough capacitive configurations.

   - Suitable for military, aerospace, industrial, medical, telecom, and computer applications¹.

3. **Other Manufacturers**:

   - **Amphenol CS** offers filtered D-Sub connectors that combine standard components with filter elements. These connectors are intermateable and interchangeable with standard non-filter connectors³.

   - **HARTING** provides filtered D-Sub connectors in various terminations (solder buckets, straight, and right-angled solder pins) and contact versions (9, 15, 25, and 37). Suitable for diverse applications⁴.

Whether you need enhanced performance or high-density filtering, filtered D-Sub connectors offer a reliable solution for your specific requirements. 🌟
