Kemet has announced the expansion of its X7R Multilayer Ceramic Capacitor Flex Mitigation Portfolio with the introduction of the FF-CAP.
The FF-CAP incorporates two existing Kemet technologies: Floating Electrode (cascading electrode design) and Flexible Termination. The Floating Electrode component yields improved voltage and ESD performance over standard designs and also mitigates the risk of low-IR or short circuit failures associated with mechanical flex cracks. The Flexible Termination component incorporates a measure of flexibility to the capacitor, shifting flex stress away from the ceramic body and into the termination area.
FF-CAP's technology combination ensures an increased measure of protection from board flex, offering up to 5 mm of flex-bend capability. This provides an enhanced level of mechanical flex crack protection for low- to mid-capacitance part types and complements Kemet's current Open Mode, Floating Electrode and Flexible Termination technologies. In addition, the new product meets the requirements of the Automotive Electronics Council's AEC-Q200-Rev C and is being offered with 100% pure matte tin-plated terminations that allow for excellent solderability.
The FF-CAP is offered in case sizes ranging from EIA 0603 to EIA 1210, with rated voltages ranging from 6,3 V d.c. to 250 V d.c. Combined with the stability of an X7R dielectric, the FF-CAP offers customers a flex robust solution in low- to mid-capacitance values and an operating temperature range of -55°C to +125°C with zero bias capacitance shift limited to ±15% over that range. Capacitance tolerances offered include J (±5%), K (±10%) and M (±20%).
