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

Buck Switching Regulator IC Positive Fixed 3.3V 1 Output 2A SOT-23-6 Thin, TSOT-23-6 The AP63200/AP63201/AP63203/AP63205 is a 2A, synchronous buck converter with a wide input voltage range of 3.8V to 32V and fully integrates a 125mΩ high-side power MOSFET and a 68mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion. The AP63200/AP63201/AP63203/AP63205 device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated compensation network. The AP63200/AP63201/AP63203/AP63205 has optimized designs for Electromagnetic Interference (EMI) reduction. The converter features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. It also has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which further erases highfrequency radiated EMI noise caused by MOSFET switching.
