The P125-H5 is a type of spring test probe (pogo pin) used for electrical testing of printed circuit boards (PCBs) and other electronic components. The "H5" style of the probe's head, oversized, 4mm "plum blossom" head with 32 teeth.

• Head type: The "plum blossom" or "flower" head shape is designed to make a more reliable connection and effectively pierce through contaminants on solder pads and pins, ensuring a secure test connection. The large 4mm diameter of the head can accommodate larger target areas.
• Series: It is part of the P125 series of spring test probes, which are known for their durability and performance.
• Materials: P125 series probes are typically constructed from high-quality, durable materials like gold-plated brass for the tube, gold-plated phosphor bronze for the barrel, and stainless steel or beryllium copper for the spring.
• Current rating: P125-series probes typically have a rated current of around 5 amps.
• Compatibility: The probe is designed to fit into a 2.4mm mounting hole, with a minimum test distance of 3.18mm.

• PCB testing: The P125-H5 is used for in-circuit testing (ICT) and functional circuit testing (FCT) to make contact with test points, lands, and pads on a circuit board.
• Electronic component testing: It is also used to test components on printed circuit assemblies and for testing long lead feet, terminals, and wire wraps.
• Contaminated surfaces: The aggressive, multi-pronged head is particularly effective for testing contaminated PCB boards or piercing through oxidized layers to make a good electrical connection.
