Murata’s very high temperature lead type capacitors suit automotive applications
General Information:
Murata introduces lead type multilayer ceramic capacitors for 200°C automobile use.
Murata Manufacturing Co., Ltd. developed the RHS series of lead type multilayer ceramic capacitors for automobile use at maximum usage temperature of 200°C. The rated voltage lineup includes 200Vdc and 500Vdc, and the range will be expanded hereafter. These products are primarily meant for use in equipment located in severe temperature environments such as the engine compartment of an automobile. Production starts in May 2017.
Features:
- Temperature -55°C~200°C
- Voltage 200Vdc and 500Vdc – range expansion in 2017
- AEC-Q200 and ISO7637-2 compliant
- Production starts in May 2017
- Complies with AEC-Q200*1 and therefore the lead wire type capacitor can be connected by welding or “crimping*2” close to a noise generating source.
- Passes the extreme surge test of the ISO7637-2*3 Standard
Explanation of Terms
*1 AEC-Q200: Test standards for reliability sought in automobile electrical parts, as decided by the Automotive Electronics Council.
*2 Crimping: A metal component or fitting is fastened using a pliers or custom tool without using an adhesive
*3 ISO7637-2: Test standards for checking durability against noise generated by automobile electrical Equipment.
Electrical Performance:
- Usage Temperature Range: -55°C~200°C
Temperature Characteristics: 7J Characteristic (See table below.)
External Dimensions:
LxW: 4.0×3.5mm or 5.5×4.0mm (Determined by the combination of rated voltage and electrostatic capacity.)
F: Can be selected from either 2.5mm or 5.0mm
About Voltage/Temperature Derating:
When the temperature of the product is to exceed 150°C, usage should be with reduction of the voltage to be applied to the capacitor for the rated voltages shown below.
