The 91930-21121LF is a Conan® 1.00mm right angle mezzanine connector featuring 21 positions, engineered for secure, high-speed interconnection in harsh industrial environments. This connector delivers comprehensive electrical performance with an insulation resistance of 1000 MO minimum, contact resistance of 30 MO maximum, and a current rating of 1.0 A continuous per contact. The connector supports differential pair signal integrity with 100 O ± 10 impedance and insertion loss less than 1.5 dB up to 5 GHz, enabling PCIe® Gen high-speed performance on selected stack heights. Its right angle configuration provides a compact mated height of 5.3 mm and width of 5.59 mm, making it ideal for perpendicular board stacking applications. The audible "click" sound during mating, polarization features, and 30 mating cycle durability ensure secure interconnection and ease of assembly, while RoHS compliance and lead-free construction meet environmental and safety requirements for communications, networking, medical, and industrial equipment applications.
