Power Connectors & Interconnection Systems Mini CROWN EDGE High Current Power Connectors for 1U/2U Pluggable VRMs (Continued) Cutout View Showing CROWN BAND Power Contacts Flexible Power Arrangements In contrast with other VRM interconnects where U-shaped contacts are used, in Mini CROWN EDGE connectors all power contacts are isolated from each other, allowing the design engineer flexibility in laying out multiple voltage rails and returns. Robust, Low-Profile Housing Design Mini CROWN EDGE connectors feature a low profile housing design that leaves more room for placement of components on the VRM board. Rigorous shock and vibration testing shows that the two latches used to hold the VRM are robust enough to safely hold 2U height modules. Voltage Regulation Module (VRM) Connectors Current Ratings As shown on the chart at right, Mini CROWN EDGE power contacts are rated at 25A at 30°C temperature rise. 160 Product Specifications Materials Insulators Contacts Finishes Contacts Electrical High Temperature Thermoplastic, UL 94V-0 flammability rated, color black Copper Alloy Selectively plated gold (30 micro inches minimum) with tin on terminations, all over nickel Current Rating UL 30 Amp, per UL 1977, para 16 Power Contacts CUR/CSA 25 Amp Signal Contacts UL 3 Amp, per UL 1977, para 16 CUR/CSA 2 Amp Contact resistance Power 2 MΩ maximum initial, (3 MΩ maximum after 250 cycles durability), at 25A Signal 10 MΩ maximum initial, (15 MΩ maximum after 250 cycles durability) Dielectric Strength 1,500 VDC for 1 minute, per UL 1977, para 17.3b Mechanical Durability Shock Vibration Operating Temperature Temperature Life Recommended PCB Hole, Compliant Press-Fit and Solder tail Marking 250 Cycles, per EIA-364-9C per EIA-364-27B, Test Condition H per EIA-364-28D, Test Condition VII -40° to +105°C 105°C for 96 hours, per EIA-364-17B, Method C Finished hole: 0.040 +/- .0030″ dia.
