As a Basic Contact Probe, F10021S090P300HP (item number 1010160) establishes a spring-loaded electrical connection to the test point. With tip style 21 (4-point crown (self-cleaning)), F10021S090P300HP combines ICT/FCT use with a geometry intended for pad surfaces and soldered pins where the crown geometry can penetrate residues or oxide layers. F10021S090P300HP combines a pitch of 2.54 mm / 100 mil with tip style 21 (4-point crown (self-cleaning)) and a tip diameter of 0.9 mm. For F10021S090P300HP, spring force is 300 cN at a nominal travel of 4.3 mm. F10021S090P300HP is rated for 5 A continuous current with a typical contact resistance of 40 mΩ. For demanding test points, F10021S090P300HP combines functional Progressive Coating with the higher preload of the HP spring, supporting reliable contact on OSP surfaces and areas affected by flux or contamination.
