Coaxial Connectors (RF) are widely used in various connections and communications. The 903-373J-51A is one of the most popular Coaxial Connectors. It is designed for applications specifically requiring high performance and low intermodulation distortion. In this article, the application field and working principle of 903-373J-51A will be discussed.
The 903-373J-51A Coaxial Connector is designed for application with 75 ohm SHF, UHF, VHF, FM and TV. It has a 1.0/2.3 series coax connector with pin contacts. The connector utilizes TNC (threaded neill-concelman) coaxial connectors. It is mainly used for high frequency and low intermodulation distortion. This connector features a non-conductive zinc die-cast shell that prevents electromagnetic interference and good resilience.
The 903-373J-51A Coaxial Connector has a rugged, waterproof construction that is highly resistant to rough handling, high temperature, and corrosion. The connector is rated for current of up to 5A and voltage up to 450V. The 903-373J-51A is suitable for applications in many fields, including networking, television and radio frequency engineering.
The working principle of 903-373J-51A Coaxial Connector involves the use of inner and outer conductors to create a transmission line. The connecting conductor is the center rod, while the outer conductor is a metallic tube most often made of copper. The outer conductor surrounding the transmission line creates an electrostatic shield to protect the signal from external interference. This type of connector is designed to provide electrical continuity while preventing electrical leakage. The capacitance of the connector is carefully controlled to ensure reliable transmission and edge sharpness.
In conclusion, the 903-373J-51A Coaxial Connector is one of the most commonly used Coaxial Connectors in the RF industry. It is designed for applications requiring high performance and low intermodulation distortion. The connector is suitable for many fields such as networking, television and radio frequency engineering. It has a rugged, waterproof construction with high current and voltage ratings. The inner and outer conductors are carefully designed to create a transmission line for reliable transmission and edge sharpness.
