High Reliability COTS (CWR11 Style)

T493 Series COTS Space Grade

Overview

KEMET's Space Grade Series of capacitors are suitable for

use by military/aerospace customers in high reliability space

applications. This series meets the requirements of MIL–

PRF–55365 as well as MIL–STD–1580. These capacitors

incorporate an intensive testing and screening protocol which

is customizable depending on specific customer requirements.

The full part number allows for designation of Weibull grading

level (C=0.01%/k hours), surge current level (10 cycles -55°C and

+85°C before and/or after Weibull grading), performance testing

level (see chart for details on available options), ESR (low and

standard), and termination finish (see description in each series).

Fused versions are available for built-in circuit protection, as well

as multi-anode designs for very low ESR values

Benefits

Applications

Typical applications include decoupling and filtering in military and

• Standard case sizes A-X per EIA 535BAAC

• Termination finishes options per MIL–PRF–55365: Gold Plated

aerospace applications.

B, Hot Solder Dipped C, Solder Plated H, Solder Fused K

• Weibull Grading C (0.01%/1,000 hours)

• Surge current testing available per MIL–PRF–55365: 10 cycles

@ 25˚C, 10 cycles @ -55˚C and +85˚C

• Standard and low ESR options available

• Operating temperature range of -55˚C to +125˚C

• Capacitance values of 0.1 μF to 330 μF

• Voltage rating of 4 – 63 VDC

Environmental Compliance

RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder.

SPICE

1、您如何理解数字孪生技术对汽车行业数字化转型的推进作用？我认为推进数字化转型企业首先必须有良好的数字化研发设计基础。在汽车产品的设计阶段，需要企业能够利用数字孪生技术提高设计的准确性，并通过虚拟仿真试验验证产品在真实环节中的性能。在汽车产品虚拟验证方面，必须要通过验证平台进行一系列可重复、可变参数、可加速的仿真实验，来验证产品在多种外部环境下的性能和表现，在设计阶段就验证产品的适应性，并通过...[详细]
10.NandFlash的驱动_写操作

上一节，学习了NandFlash的按页读的操作，下面是实现NandFlash的按页写。首先还是查看NandFlash芯片K9F2G08U0A的时序图根据I/O pin角的信号信息，知道要实现NandFlash的写操作需要的步骤如下：最后实现按页写的函数： int NF_WritePage(unsigned long addr, unsigned char* buff) { int...[详细]
“骁遥”增混电池背后的四大产业变化

临近年末，宁德时代聚焦增混汽车场景，推出了今年以来的第二个电池品牌“骁遥”。不同于此前麒麟、神行系列着重宣传快充电池的命名意图，今年来天行、骁遥品牌的推出，均以不同的动力电池使用场景为分类依据。这背后蕴含着宁德时代对于新能源车和动力电池产业变化的最新判断。结合市场行情来观察，主要体现为以下四点：其一，增混汽车的市场定位，正发生从“过渡产品”到“独立品类”的变化。 ...[详细]

23.核心初始化之中断屏蔽-2440

在上一节中，我在设置关闭看门狗的时候，已经把WTCON的设置为0，屏蔽了中断。如下图：这一节是要屏蔽中断寄存器：下面是2440芯片处理中断的机制：中断屏蔽寄存器：可以看到，只要把中断对应的中断屏蔽寄存器对应的位置为1即可。所以屏蔽中断就是往中断屏蔽寄存器置为全1，就屏蔽了所有中断。编译： ...[详细]
国产汽车级大电流霍尔电流传感器应用案例分享

国产车规级霍尔电流传感器CH704是为50A以上大电流检测应用开发的隔离集成式电流传感芯片，具有高精度、增强绝缘耐压、高可靠性、低功耗等优点。该芯片内部集成一个精密的可编程线性霍尔芯片、一个小型聚磁环以及一个导通电阻为0.1mΩ的铜排，可实现+/-50A,+/-100A,+/-150A,+/-200A的电流检测，并且通过工厂预编程可测量最大400A的浪涌电流。内部的低偏移、斩波稳定的线性霍...[详细]
