【应用】1pF~12µF、10VDC~1000VDC片式多层陶瓷电容器CEC系列助力海上军事设施中的电子系统设计
电容器作为电子系统中常用的元器件,具备储能交换、隔直通交(旁路/耦合)、鉴频滤波以及浪涌电压抑制等功能。而片式多层陶瓷电容器(MLCC,Multi-layer Ceramic Capacitors)作为电容器的一种,凭借可靠性高、比容大、使用寿命长、体积小以及成本低等优势,被广泛应用在军事领域。对于海上军事设施中的电子系统(如武器控制系统、雷达系统、军事通信系统等)设计,为了保证系统的高可靠性,通常要求元器件具备耐高压、绝缘电阻高以及可靠性高等优势。
针对此,对于片式多层陶瓷电容器解决方案的选取,本文推荐采用EXXELIA公司提供的CEC系列片式多层陶瓷电容器,电容值范围为1pF~12μF,工作温度范围宽至–55°C~+125°C,具备出色的环境适应能力。同时,该系列的电介质提供NPO、BX、2C1以及X7R四种,对于NPO、X7R电介质的电容器,其额定电压(URC)为10VDC~1000VDC,对于BX、2C1电介质的电容器,其额定电压为10VDC~500VDC。对于NPO电介质的电容器,在不同额定电压下的介质耐压为2.5URC(URC≤500VDC)、1.6URC(URC=1000VDC)、1.5URC(URC=1000VDC);对于BX、2C1电介质的电容器,在不同额定电压下的介质耐压为2.5URC;对于X7R电介质的电容器,在不同额定电压下的介质耐压为2.5URC(URC≤500VDC);优异的耐高压特性,可满足海上军事设施的系统设计要求。
图2 不同尺寸(以0402/0403/0603为例)下的尺寸、电容值以及额定电压信息
值得一提的是,CEC系列提供多种不同的尺寸( 0402 ~ 3040),例如,0402/0403/0603对应的尺寸信息、电容值以及额定电压信息如图2所示。另外,CEC系列的绝缘电阻可高达100000MΩ,绝缘性能好,安全可靠,可以适应海上军事设施苛刻的工作环境。对于BX、2C1以及X7R电介质的电容器,在整个工作温度范围内,并且在没有施加直流电压的情况下,其最大ΔC/°C为±15%;而NPO电介质的电容器的温度系数为(0±30)ppm/°C,温度稳定性好。该系列的订购信息如图3所示,更多的产品解决方案和元器件的在线采购可以在世强官网搜索获取。

MULTILAYER CERAMIC CAPACITORS MLCC
Our multilayer ceramic capacitor (MLCC) is a chip capacitor manufactured with layers of ceramic material and metal. The alternating layers can be built up to the desired capacitance range. The dielectric thickness determines the voltage rating. The capacitance is determined by multiplying the number of layers by the amount of active area and then the dielectric constant for the material. This number is then divided by the dielectric thickness. The active area is the overlap between the electrodes. A capacitor with a thicker dielectric layer handles higher voltages than one with a thinner layer. Inversely, the thinner dielectric will have a higher capacitance rating. The MLCC design provides a significant space-saving advantage over other capacitor styles.
