The BSC PREFERRED STC340 is a case of 100 anti-static shielding bags designed to protect ESD-sensitive electronic components from electrostatic discharge damage. Each bag features a transparent, multi-layer film construction that guards against static charges, making the contents visible without removing the bag. A zip-top seal keeps parts secured and allows repeated access without compromising protection. The ESD warning symbol is printed directly on each bag, providing clear visual identification for technicians handling sensitive assemblies. These bags are intended for commercial use in electronics service, assembly, and storage environments.
The STC340 shielding bags are suited for storing and transporting circuit boards, capacitors, sensors, control modules, and other electrostatic discharge-sensitive devices. They are commonly used in HVAC, electrical, and electronics service operations where replacement control boards and electronic components must be staged, stored, or shipped without risk of ESD damage. Each case contains 100 bags, making it practical for shop stock or field service kits. This product is equivalent to part number S-5310.
