EMI suppression capacitors with steady performance at high requirements:
KEMET’s R41B series new at Rutronik
R41B series capacitors for applications with Y2/X1 safety classification.
Ispringen, August 2023 – KEMET’s R41B film capacitor series complements Rutronik’s product
portfolio. The capacitors have voltage ratings of 350 VAC (rated voltage) and up to 1500 VDC
(rated DC voltage) and passed 1,000 hours of operation at rated voltage applied in the
accelerated THB test at temperatures of 85 °C and humidity of 85 %. They offer the ideal solution
for use in harsh environments and are also available in a halogen-free version on request at
www.rutronik24.com.
The film capacitor range with protection class Y2/X1 is currently the first on the market to combine THB
class IIIB with high operating temperature and high capacitance value while offering the smallest lead
space of a minimum of 10 mm. The capacitors are made of metalized polypropylene film coated with
self-extinguishing resin and are UL/ENEC/CQC certified. They are for use in a capacitance range of 2.2
nF to 1.2 µF and deliver a high-temperature capability of up to +125 °C. In addition, they are AEC-Q200
compliant and intended for use in filters to suppress electromagnetic interference in “line-to-ground” (Ycapacitor) and “cross-the-line” (X-capacitor) applications.
Features at a glance:
• Capacitance range from 0.0022 μF – 1.2 µF
• Smallest lead spacing with class IIIB
• Class IIIB according to IEC
• Suitable for harsh environments
• Automotive Grade (AEC-Q200)
• High-temperature capability from 125 °C up to 2000 h
Target Application:
• HVDC filter
