Driven by demands for more robust and more reliable components, AVX has extended the capacitance ranges of its Flexiterm family.
Flexiterm, a recently introduced, soft termination system, delivers enhanced mechanical strength and temperature cycling performance for ceramic capacitors in X7R dielectric. Flexiterm enables superior mechanical and thermo-mechanical performances in applications subject to high degrees of board flexure.
New Flexiterm X7R values include a 1 μF, 10 V, 0805 chip-sized part and a 0,47 μF, 50 V component.
Enhancing the capabilities of a standard MLCC, Flexiterm has been developed to guard against crack failures under extreme environmental conditions. Using base metal electrode (BME) technology, flexible copper terminations are coated with a conductive polymer and subsequently plated with nickel and tin. The system guarantees a minimum damage-free flexure of 5 mm, achieving 3000 temperature cycles compared to an industry standard of 1000. As a further benefit, the component will fail 'open-circuit' beyond 5 mm.
Flexiterm is suitable for high flexure stress circuit boards, variable temperature applications and automotive applications.
