FX30B-4P-3.81DSA25 are one type of fifth generation rectangular connectors, which belong to the category of “Headers, Male Pins”. It’s widely used on electronic, electrical, and communication equipment due to its high performance and reliability. The performance and working principle of FX30B-4P-3.81DSA25 make it an ideal choice for commercial, industrial and military applications.

FX30B-4P-3.81DSA25 has metalized contacts to ensure extremely reliable contact performance. It offers excellent electrical properties such as low insertion force, low contact resistance, and high electrical conductivity. The special design of the shell also provides excellent thermal performance. It has a large contact area with four contacts offering 20A current per contact.

The working principle of FX30B-4P-3.81DSA25 is based on the theory of contact resistance and heat transfer. When two terminals of the header are brought into contact with each other, the contact resistance creates a small gap between the two surfaces. This gap increases both the electrical and thermal conductivity of the connection. The contact force is determined by the spring force of the spring-loaded contacts. It ensures that the contact resistance is maintained even when pressure is applied on the connection. The number of contact points increases with increasing spring force.

It can be used for a wide range of applications, including automotive, industrial, medical, telecommunications, and consumer electronics. It is suitable for mating with surface mount pads and components. It also has features such as sealed shell and locking screw to protect it from environmental conditions and prevent accidental disconnection.

The FX30B-4P-3.81DSA25 is suitable for high-frequency applications that require low cross-talk and common-mode interference. It also provides good dielectric strength and safe operation, and the slow-make and slow-break contact design ensures reliable connection. The connector is also immune to EM interference and offers superior signal integrity.

The FX30B-4P-3.81DSA25 is a versatile connector that can be used in many applications due to its excellent performance and reliability characteristics. Its electrical characteristics make it suitable for a wide range of applications, such as automotive, medical, consumer electronics, telecommunications, and industrial applications.
