When taking measures against noise that occurs from motors for cars, it is important to arrange noise suppression products in a space as close as possible to the noise source (motor).
It is also necessary for a capacitor to endure high temperatures depending on the installation location of the motor.
As a technique to achieve noise suppression, we recommend that leaded products be mounted by welding without using a printed circuit board.
In an example of actual use, as shown in the figure on the right, ceramic capacitors guaranteed for high temperatures (125°C, 150°C), which comply with AEC-Q200 or ISO7637-2 (Surge Test), are mounted by welding while the lead wires are bent.
Murata's "RCE Series" and "RH Series" have ideal features for such usage.
