The 105-1101-001 is a horizontal insulated miniature test jack designed for probe and measurement applications. It features a copper aluminum alloy contact with silver finish and a nylon 6/6 body (ASTM D4066), rated for 5 amps continuous current and 2100 Vrms breakdown voltage minimum. The contact resistance is maintained at 0.010 ohms maximum, with adjacent jack capacitance of 1 pF maximum at 1 MHz, ensuring minimal signal distortion. The design includes contact protection from flux and solder, probe access from both ends, and UL-approved self-extinguishing nylon construction. This test jack is ideal for laboratory instrumentation, electronic testing, and measurement systems where reliable electrical contact and signal integrity are essential.
