This item contains 10 pieces of 18-pin IC sockets. These sockets are designed to securely hold integrated circuits (ICs) and protect them from physical damage. The main benefit of these sockets is to easily exchange the ICs in your circuit without the need to (de)solder them. This means it takes very little effort to change a (defective) chip when you need to update your circuit or development board. Made from high-quality materials, these sockets are durable and long-lasting. Whether you're building a simple circuit or a complex system, these IC sockets will provide you with the stability and reliability you need.
