Overview

ESQT-138-03-S-6-375 is a rectangular connector in the Headers, Receptacles, and Female Sockets category. It supports three pins, rated at 6 Amps per pin. It\'s an ideal choice for boards with higher contact density and moderate power requirements. This connector is well-suited for cost-effective interconnection solutions.

Application Fields

The ESQT-138-03-S-6-375 connector, being a robust and reliable interconnection device, can be used in a variety of applications in the fields of consumer electronic devices, automotive, industrial, medical, telecommunications, and military and aerospace. The application fields can be divided into two main groups:

• High power applications with high contact density, such as power control systems
• Moderate power applications with higher contact density, such as PCBs, surge-protection assemblies

Working Principle

The ESQT-138-03-S-6-375 connector has three pin contacts and a rectangular housing with two mating surfaces. Each pin contact consists of two tabs with two open-ended slots. A male component, with three pins protruding from its body, is inserted into the female component\'s housing. When in place, the tabs of the female component lock around the pins of the male component. This creates a secure, mechanically-solid electrical connection between the two components. The female component\'s locking tabs can be easily retracted to enable the removal of the male component from the housing.The contact resistance of the ESQT-138-03-S-6-375 connector is rated up to 25 mΩ and rated current up to 6 A per pin. The contact insert is gold-plated for superior electrical and mechanical performance and low contact resistance. The housing material is made from PC/ABS for superior flame retardancy and corrosion protection. The housings are designed to ensure excellent mating durability.

Advantages

The ESQT-138-03-S-6-375 connector offers some key advantages:

• Compact size and high contact density, suitable for boards with limited space
• High contact force and current rating
• Gold plated contacts for superior electrical and mechanical performance
• Excellent mating durability
• Cost effective interconnection solution.

Conclusion

The ESQT-138-03-S-6-375 rectangular connector is a versatile and reliable interconnection device, suitable for a wide range of applications in the fields of consumer electronic devices, automotive, industrial, medical, telecommunications, and military and aerospace. Its high contact force and current rating, gold plated contacts, and excellent mating durability make it an ideal choice for cost-effective interconnect solutions.
