Overview of 221789-1 by TE Connectivity
The 221789-1 is a Radio Frequency SubMiniature version A (RF SMA) connector, specifically designed as a jack for printed circuit boards (PCBs). This component, crafted by TE Connectivity, offers a characteristic impedance of 50 Ohms and is suited for high-frequency applications up to 4 GHz. The connector provides a straight mounting style, allowing for a secure and reliable connection oriented in alignment with the PCB’s surface.
This model boasts a solder termination type, which facilitates a sturdy mechanical connection as well as excellent electrical continuity between the connector and PCB. The connector itself is made from brass with a gold shell finish, and the termination features gold, ensuring good conductivity and resistance to oxidation. Notably, its durability is highlighted by a 500-cycle rating, which refers to the number of times it can be mated and un-mated before the material quality begins to degrade.
Key to its performance in sensitive applications, the 221789-1 has a Voltage Standing Wave Ratio (VSWR) better than 1.3, indicating efficient signal transmission with minimal reflection. Furthermore, the operating temperature range spans from -65 °C to 165 °C, making it a robust choice for varied environmental conditions. The 221789-1 meets Rohs compliance standards, helping in ensuring that it meets current environmental regulations concerning hazardous substances.
