Murata innovates capacitor termination less prone to mechanical stress for automotive applications.

Murata announced the GCJ series of monolithic ceramic capacitors designed to accommodate the bending, vibration and thermal conditions experienced in under-bonnet automotive applications. Meeting the automotive market requirements by failing-safe against a short circuit, the company have incorporated a soft termination with the ceramic body.

This approach uses a conductive resin on the outer electrodes to absorb any excessive mechanical stress resulting from board flexing or temperature cycles. Typically, when subjected to undue mechanical bending forces, a ceramic capacitor can crack causing a short circuit. This needs to be avoided in any automotive application, especially when used in power circuits.

The GCJ series of X7R capacitors is available in 0603, 0805, 1206 and 1210 packages. All popular capacitance values from 1nF to 10uF are available in 10, 16, 25, 50 and 100 working voltage.
