Rectangular connectors have been around for decades and have become increasingly popular in the digital age. Among rectangular connectors, ESQT-108-03-L-D-408 is one of the most commonly used connectors. In this article, we will discuss the application field and working principle of ESQT-108-03-L-D-408.

Description of ESQT-108-03-L-D-408

ESQT-108-03-L-D-408 is an 8-positions, 2-row, 300V, 16A male rectangular header with a long pin length. It has a white plastic body material, with a header height of 8mm. Its maximum contact resistance is 30 mΩ. It is a high-reliability connector that is designed for power and signal applications. Its contact terminals are gold-nickel-plated brass.

Application Field of ESQT-108-03-L-D-408

ESQT-108-03-L-D-408 can be used in a variety of applications, such as communication systems, industrial and automotive control systems, medical equipment, and computer peripherals. Its high-reliability and small size make it an ideal choice for high-density applications. Its zinc die-cast housing provides superior protection and reliability even in harsh environmental conditions. Its ability to operate in -40°C to 85°C temperature enabled its application in automotive networks, such as CAN bus, LIN bus, and powertrain applications.

Working Principle of ESQT-108-03-L-D-408

ESQT-108-03-L-D-408 has a working principle of mate-and-lock. It uses a metal latch which is retained in a rectangular slots of the hood to hold the connector in place, and the hood\'s male tabs engage with the female sockets to securely hold the connector in place. This ensures reliable connection even when shock and vibration are present.

When two connectors mate, the current passes through the electrical interface and is connected from the male to the female socket. The connector is designed to achieve reliable electrical connection, with gold-nickel-plated brass contacts having contact resistance of 30mΩ or less. This helps to ensure reliable and stable power transmission over time.

To disconnect the interface, the male header is pushed while holding down the metal latch. This will disengage the male headers from the female sockets, and the two connectors can then be disconnected. This ensures safety and prevents accidental detachment.

Conclusion

In conclusion, ESQT-108-03-L-D-408 is an 8-positions, 2-row, 300V, 16A male rectangular header with a long pin length. Its application field is broad, which includes communication systems, industrial and automotive control systems, medical equipment, and computer peripherals. Its mate-and-lock working principle makes it secure against shock and vibration, and its gold-nickel-plated brass contacts offer reliable power and signal connection. With all these features, ESQT-108-03-L-D-408 is definitely a reliable choice for high-density applications.
