Molex Straight Female PCB Mount SMA Connector Jack, 50Ω Impedance, 1.425g - 73412 Series - 73251-3140


This connector jack from Molex provides a reliable connection point for SMA (SubMiniature version A) coaxial cables on printed circuit boards (PCBs). This component has a centre contact made of gold-plated beryllium-copper material, which is highly conductive and corrosion-resistant, so it ensures a strong and long-lasting connection. Thanks to the jack's low impedance of 50Ω (ohms), there's minimal resistance to energy flow, ensuring you get speedy signal transmission. You'll find this type of component commonly used in communication devices.

• Light weight of 1.425g to minimise bulk and strain on your equipment
• Maximum process temperature of +260°C for ease of soldering
• Straight orientation for easy linking with coaxial cable
• Through-hole mounting style for simple installation on a PCB

Applications


• Radio frequency (RF) communication devices
• Satellite antennae

How frequently can I use this jack without causing excess wear?


Frequent disconnection and connection cycles can cause wear and shorten the lifespan of the jack. This one's designed to handle two cycles per day at the maximum operating temperature. If you disconnect and reconnect cables more frequently, this jack will be more likely to wear down quickly.


Molex SMA RF Coaxial Connectors


The Molex range of high- performance SMA RF Coaxial subminiature Connectors are suitable for microwave frequencies. The SMA design of threaded couplings gives uniform contact of the outer conductors to reduce reflections and attenuation at higher frequencies. High mechanical strength and durability are also ensured by the threaded SMA design.
