TDK produces a new series of automotive laminated ceramic capacitors

TDK Co., Ltd. has developed a new series of automotive laminated ceramic capacitors with a temperature characteristic of C0G characteristics and a rated voltage of 100V to 630V, and has started mass production since April. This series has the C0G characteristic, and has the highest level of electrostatic capacity in the medium voltage field with a rated voltage of 100V to 630V. In particular, the series realizes static electricity of 100nF in a size of 5750 (5.7mm×5.0mm, EIA:2220). Capacity (rated voltage 630V). This is the highest electrostatic capacity of the world's first ※ industry in the same rated voltage.

In recent years, with the popularization of electric vehicles and hybrid vehicles, the electronic level of automobiles has been increasingly improved, and among them, laminated ceramic capacitors used as vehicle-mounted electronic components are required to meet requirements for high reliability, compactness, and large capacity at the same time. .

In order to meet such market requirements, TDK combines its own expertise in micronization of dielectric materials, high dispersion technologies, and thin-layer and multi-layered technologies of dielectric ceramic layers, with a wide range of product sizes (1005 to 5750 dimensions). : EIA0402 to 2220) The expansion of the electrostatic capacity and the high reliability required for automotive products have been achieved. In addition, this series of voltage rated 450V series (2012 size and above) and 5750 size has also been serialized to further enrich the product range to meet various needs in the market.

The temperature characteristics of this series are C0G characteristics (temperature range: -55 to 125°C, temperature coefficient: 0±30ppm/°C or less) and can be used not only in automotive ECUs but also in power supplies for consumer products, industrial machinery, etc. A variety of circuits (time constant circuits, filter circuits, resonance circuits, oscillation circuits, and buffer circuits) are required in products requiring high reliability, and at the same time, the film capacitors can be replaced by increasing the rated voltage and electrostatic capacity. In addition, we will respond to customers' different needs (such as supporting 150°C, etc.).

Main features and advantages of main applications include automotive engine control components, keyless entry systems, EV/HEV inverters and DC-DC converters, non-contact power supply resonant circuits, general consumer products, power circuits, and sensors. The temperature characteristics are C0G characteristics (temperature characteristics: -55 to 125°C, capacity temperature coefficient is within 0±30ppm/°C), and do not change with the temperature and time of the DC bypass characteristics and capacity, and the output value can be guaranteed in accordance with the design to support the rated voltage. 100V to 630V range, replaceable film capacitors meet AEC-Q200
