Battery Holder (Open) 9V 1 Cell PC Pin 9V battery holder through hole The BH9VPC is a through-hole, printed circuit board–mount battery holder designed to accommodate a single standard 9 V (PP3) battery. It provides a secure mechanical enclosure and reliable electrical interface for powering electronic assemblies directly from a PCB. The holder is constructed from durable insulating material with integrated metal contacts to ensure stable retention and consistent electrical connection during operation. Its form factor supports straightforward integration into compact designs while maintaining ease of battery replacement. Engineering Specification: The component is intended for through-hole mounting using PC pins that provide both mechanical stability and electrical connection to the circuit board. It supports one 9 V battery with standard snap terminal interface internally routed to PCB pins. The housing material is typically molded plastic with good mechanical strength and electrical insulation properties suitable for general electronic applications. Contact terminals are metal, commonly nickel-plated or equivalent, to ensure low contact resistance and corrosion resistance over repeated battery insertions. The holder is designed for vertical mounting orientation relative to the PCB, with a compact footprint suitable for space-constrained layouts. It provides sufficient retention force to secure the battery under normal handling and vibration conditions encountered in consumer and light industrial electronics. The operating characteristics are aligned with typical 9 V battery usage, supporting low to moderate current applications depending on battery capability. The part is compatible with standard wave soldering processes used in through-hole assembly. It is intended for use in ambient environmental conditions typical of indoor electronic equipment and is not inherently sealed against moisture or contaminants. The design allows easy manual insertion and removal of the battery without specialized tools, supporting maintenance and replacement in field applications. #commonpartslibrary #batteryholder

Polymeric PTC Resettable Fuse 60V 500 mA Ih Surface Mount 2-SMD 500mA resettable fuse pptc The SMD050F-2 is a surface-mount resettable fuse (PPTC – Polymer Positive Temperature Coefficient) designed to provide overcurrent protection in low-voltage electronic circuits. It operates by increasing its resistance significantly when excessive current flows, thereby limiting current and protecting downstream components. Once the fault condition is removed and the device cools, it automatically resets to its low-resistance state, enabling normal operation without replacement. This component is commonly used in power supply lines, USB ports, battery-powered devices, and general electronic protection applications where space-saving and reliability are important.
