f-9124 2/07 surface mount ceramic chip capacitors ? x7r dielectric as detailed in the kemet surface mount catalog f3102 for x7r, with following specific requirements based on room temperature (25c) parameters: ? operating range: -55c to +125c, with no-bias capacitance shift limited to 15% over that range. ? insulation resistance (ir) measured after 2 minutes at rated voltage @ 25c: limit is 500 megohm microfarads or 10g , whichever of the two is smaller. ? capacitance and dissipation factor (df) measured at the following conditions. 1 khz and 1 vrms. df limits for 50v product is 2.5% and 3.5% for 25v product. these components are suitable for reflow soldering only. all parts incorporate the standard kemet barrier layer of pure nickel, with an overplate of pure tin to provide excellent solderability as well as resistance to leaching. these chips will be supplied unmarked. however, marking is available as an extra cost option. aec-q200 rev. c - automotive rohs 5 - snpb termination rohs 6 - 100% tin termination in general, the information in the kemet surface mount catalog f3102 applies to these capacitors. the information in this bulletin supplements that in the catalog. (1) insert capacitance tolerance k for 10% or m for 20%. these components are also available with snpb plated nickel barrier termination as an option. electrical parameters soldering process marking qualification/certification
