The 8428-21B1-RK-TR is a type of socket for ICs, transistors, and other electronic components that require precise electrical connections. These sockets allow for the chips and transistors to be inserted and removed without damage or risk to vital connection nodes. The 8428-21B1-RK-TR is a practical and economical socket for a myriad of applications such as prototyping, PCB assembling, and system testing.
The 8428-21B1-RK-TR socket is a two-piece Through Hole (TH) receptacle featuring a durable, black thermoplastic body with gold plated contacts that provide current transmission with superior electrical integrity. The contacts accept components with pins from a range of 0.1” to 0.6”. The snap-in mount allows for stacking and allows multiple sockets to be connected together with ease. The materials and construction of the socket ensure long-term reliability, with a current rating of 5A and a voltage rating of 250V.
These TH IC Sockets allow for easy socketing as the body of the socket has two slots that can accept a tool such as a pair of pliers or tweezers to push the contact blades downward and secure the socket in place. When inserting or removing components, a little bit of force is needed to open or close the socket, but the sound of a click ensures that the blade has fully closed, providing an electrical connection with the IC or transistor. Additionally, the latching pawl on the socket locks the IC in place and provides a sense of security and vibration resistance.
Furthermore, design considerations make the 8428-21B1-RK-TR socket a project-friendly component. The low-profile design makes it compatible with any board mounting, and the wide open front end allows the user to easily install and remove integrated circuits. Additionally, the angled socket body ensures proper and reliable connections, providing low impedance and great static protection against ESD and EMI. The pins of the socket are also lacquered in order to prevent soldering flux or flux from remaining in the connections.
In conclusion, the 8428-21B1-RK-TR socket is a reliable and cost-effective choice for a variety of ICs, transistors, or other electronic components that require a secure electrical connection. Its wide range of features and simple design make it a favorite among hobbyists, as well as professionals in PCB assembling and circuit testing.
