High-current Y2/X1 film capacitors for wide-bandgap power supply systems R41D V234
The YAGEO Group is expanding its range of film capacitors with the R41D V234 series, a new generation of high-current-capacity, metallised polypropylene capacitors (Y2/X1) for EMC suppression, specifically designed for modern broadband power converters. Based on the proven R41D platform with high voltage rise rate (dV/dt), the V234 series, with its C-specification, significantly improves the ability to withstand residual ripple. This enables developers to easily handle the higher switching speeds and transient currents of SiC and GaN devices. With a capacitance range of 0.001 µF to 0.22 µF, a rated voltage of 300 V AC (50/60 Hz) and a recommended DC voltage of 1200 V DC, the R41D V234 series offers reliable EMC suppression in compact radial packages. High voltage rise rates and improved resilience to residual ripple: Broadband power converters generate higher transient loads on passive components.
The R41D V234 series addresses these challenges by:
- High dV/dt rating of 6000 / 4500 / 3000 V/µs (10 / 15 / 22.5 mm pitch)
- Up to approximately twice the Irms rating compared to standard versions
- Metallised polypropylene film technology for consistent performance
The improved ripple current handling capability enables designers to reduce the number of capacitors required in EMC filters, thereby reducing the number of components, costs and PCB space requirements. Designed for reliability and harsh environments.
The R41D V234 series is designed for long-term reliability and demanding operating conditions, and features the following characteristics:
- High temperature resistance: +125°C
- Long service life in hot and humid environments (THB)
- Long operating life.
These features make the series suitable for both industrial and automotive power electronics systems. Compliance and readiness for use in the automotive sector.
The R41D V234 series meets global safety and environmental requirements, including:
- Safety classification Y2/X1
- AEC-Q200 compliance
- RoHS, REACH and halogen-free compliance
Typical applications include EMC filtering in high-power power supply systems such as:
- On-Board-Charger (OBC)
- DC/DC-Converter
- Solar inverters and energy storage systems
- Charging stations for electric vehicles
- Three-phase UPS systems
- HVDC filters and EMC filtering for AC inputs
If you are working on a power conversion system based on wide-bandgap transistors and require a safety capacitor in the Y position, the R41D V234 is the ideal choice. It is the first in the industry to combine high dV/dt and Irms performance. This reduces the number of capacitors required to filter transients and ripple currents, which frequently occur in wide-bandgap systems – simplifying your design and making it more cost-effective.
Furthermore, you benefit from the R41D’s high THB rating and high temperature resistance, which help improve system reliability in harsh and hot environments and extend the service life of your product.
Safety approvals and AEC-Q200 compliance facilitate global deployment in automotive and non-automotive applications.
