Application Field

SQT-133-03-L-5 is a rectangular connector system manufactured by Samtec Inc. The series is designed to provide high-quality signal and power conduction in a space-saving form factor. These flexible and compact connectors are ideal for high-speed signal paths, power modules, RF signals, and medical equipment applications.The metric-sized connectors are used to connect a variety of different circuits and components together quickly and easily. The series has both headers and receptacles in different pin and row configurations, as well as Female Sockets. They are available with through-hole, surface mount, and right angle options. The angled options and various surface mount heights offer a variety of solutions for many different applications.

Working Principle

The SQT-133-03-L-5 connectors feature a tine-based contact system. The tines are comprised of gold-plated copper material that produces low contact resistance and excellent electrical performance. The large pin size of the series ensures reliable connectivity in the most rigorous environments.The series connectors are engineered to mate using a patented retention force technology. The connectors can be inserted and locked by pressing them together until the pins press through the insertion slots located in both the header and receptacle. This provides a secure connection that is durable and reliable.The connections can be quickly released by using a standard graphic tool. All of the contacts feature a contact tine that extends beyond the retention force level and into the release area. This allows a release motion and prevents the connector from disengaging on its own.The SQT-133-03-L-5 connectors are designed to withstand high levels of shock and vibration. The Board Lock™ technology helps to minimize vibration disconnects in high shock or vibration environments. The receptacles are also designed to reduce mating force over time, ensuring a long-lasting connection.The series also features insulation resistance and dielectric testing for additional protection. The insulation resistance test is performed to measure the connector’s ability to withstand current levels and prevents premature failure. The dielectric test, on the other hand, evaluates the connector’s ability to resist voltage reset and arc fault.

Conclusion

The SQT-133-03-L-5 series of rectangular connectors manufactured by Samtec Inc. is a perfect solution for a variety of applications, ranging from high-speed signal paths to power modules. The series is designed to provide reliable and secure connections in the most demanding environments. The patented retention force technology ensures a secure connection and prevents accidental disconnects. The connectors also feature insulation resistance and dielectric testing to ensure a long life and maintain excellent electrical performance.
