Development of Multilayer Ceramic Chip Capacitor by TDK
In recent years demand for on-board electronic components that can contribute to the miniaturization of electrical devices and save space is on the rise. Furthermore, the number of electric devices installed in limited space is increasing. In respond to these market needs TDK has announced the development of multilayer ceramic chip capacitor (MLCC) with a rate voltage of 100V targeted at mid range applications. The new developed MLCC will contribute in reduction of the gaps between ceramic dielectrics layers by approximately 40% compared to earlier products. The new MLCCs have the same capacitance of earlier TDK components at an approximately 50% smaller form factor. Additionally, the new device features X7S temperature characteristics resulting in operating temperature range of -55°C to 125°C with change in capacitance of ±22%, making them ideal for use in engine compartments as well as the switching power supply smoothing circuits needed for industrial equipments. The Smoothing circuit is a type of electronic circuit that uses capacitors and other components to control pulsating current included in rectified current by releasing stored charge, producing smoother current. The mass production of the new MLCC is scheduled to begin in July.
