Safety Capacitors
Safety certified capacitors for interference suppression in AC line filtering applications
Overview
KEMET’s safety certified film capacitors are specifically designed for conducted emissions attenuation in AC line filtering applications. The self healing capability of film capacitors makes them a great choice for safety across power lines as well as having internationally recognized safety certifications. These capacitors are well-suited for applications that require keeping potentially disruptive or damaging line transients and EMI out of susceptible equipment.
Product Series | Applications | Benefits and Characteristics |
---|---|---|
R53 X2
|
R53 series is ideal for harsh environments and is AEC–Q200 qualified. Due to its miniaturized dimensions, this series is an excellent option in space-constrained applications. |
|
R52
|
For worldwide use in electromagnetic interference (EMI) suppression in across-the-line applications that require X2 safety classification. Typical applications include connection in series with the mains, capacitive power supplies and energy meters, with special emphasis in automotive applications for severe ambient conditions. |
|
R41T
|
For use in electromagnetic interference (EMI) suppression filter in “line-to-ground” and “across-the-line” applications, requiring Y2/X1 safety classification. |
|
F862-V054
|
Typical applications include connection in series with the mains, capacitive power supplies and energy meters, with special emphasis in automotive applications for severe ambient conditions. |
|
R4Y Y1
|
The R4Y can be widely used in automotive, EV charging station, and general industrial applications where Y1 class safety is needed in a harsh environment. |
|
R58 X1
|
Typical applications are the EMI filter stage (across the main) where X1 safety classification is needed. For example, energy storage, inverters, and general industrial where high THB performance (Grade-IIIB) and high current are required. R58 can also be used in automotive applications such as the HVDC EMI filters where >800VDC is required. |
|
Across the Main (EMI Noise Filtering)
- Line-to-line (X rated) for differential mode (DM) noise
- Line-to-ground (Y rated) for common mode (CM) noise
In Series with the Main
- Capacitive Power Supplies
- Power Line Communication (PLC)
