SMP253 and SMP255 Series Class Y2/X2 SMD Safety Capacitors
The SMP253 and SMP255 series are manufactured using metalized paper, a technology proven to guarantee high insulation resistance and self-healing properties. Metalized paper technology is ideal for guaranteeing high robustness due to the open circuit failure mode, supporting the most demanding reliability requirements for safety capacitors with no need for redundancy. This is coupled with a solid voltage pulse handling capability, doubling the performance of typical film safety capacitors.
The SMP253 Y2 and SMP255 X2 capacitors can meet high reliability and high THB class requirements with surface-mount technology. These key characteristics offer significant advantages to designers looking for robust, surface-mount safety capacitors. SMP253 and SMP255 are well-suited for AC/DC converters in onboard chargers for xEVs, smart grid hardware, EMI filtering in Variable Frequency Drives (VFDs), and high energy density applications such as capacitive power supplies.
