This utility model discloses a miniaturized
ceramic dielectric chip, belonging to the field of
capacitor technology, to solve the problem that when the edge of a disc
ceramic capacitor contacts the circuit board,
stress concentration easily leads to edge breakage, which not only reduces the product yield but may also affect the reliability and service life of the entire circuit
system. This utility model uses Y5U
ceramic material with a
dielectric constant of 8500-9200 as the ceramic
dielectric substrate. Its shape is a cube with dimensions of 7×5×1.2mm. The four corners of both the front and back sides are chamfered, and the ends of the vertical edges on all four sides are rounded at the chamfer connections, with an
arc length of 0.4mm-0.5mm. Within this arc range, the
stress concentration problem during mounting is effectively alleviated, the
structural stability of the
chip is ensured, and the
electric field distribution is optimized.
