922309 is a solderless breadboard from the 300 Series designed for easy, solderless plug-in circuit building. It features terminal positions with electrically connected tie-points spaced on a continuous 0.100" matrix to accept any component with 0.100" lead spacing. The breadboard includes five-way binding posts for interface connections from power supplies, signal generators, or other equipment. It is constructed with a steel base featuring a baked enamel finish and rubber feet to prevent sliding during benchwork. Jumper wires are included for convenient prototyping. This EU RoHS compliant breadboard is ideal for electronics prototyping, educational applications, and circuit development.
