Vishay Boosts Power Capacitor Voltage Ratings to Simplify High-Power Designs
Event summary
- Vishay Intertechnology has expanded its 193 PUR-SI series of snap-in power aluminum capacitors to include voltage ratings of 550V and 600V.
- The new capacitors aim to simplify designs for DC bus voltages up to 1100V, traditionally achieved with multiple components and voltage balancing circuits.
- These devices offer up to 30% higher ripple current than standard solutions in similar sizes and a useful life of 5000 hours at +105°C.
- Production quantities are available now, with an 18-week lead time.
The big picture
Vishay's move addresses a common design challenge in high-power applications, reducing component count and complexity while improving reliability. This innovation positions Vishay favorably within the broader trend of increasing power density and efficiency in electronics, particularly in sectors like electric vehicles and industrial automation. The longer lead times suggest potential supply chain constraints or high demand, which warrants monitoring.
What we're watching
- Design Adoption
- The rate at which power supply designers adopt these higher-voltage capacitors will depend on the perceived cost savings and reliability improvements versus existing solutions, potentially impacting Vishay’s market share in power electronics.
- Competitive Response
- Competitors in the power capacitor market will likely evaluate Vishay’s offering and may respond with similar higher-voltage solutions, intensifying price pressure and potentially driving further innovation.
- EV/HEV Demand
- The growth in electric and hybrid electric vehicle production, a key application for these capacitors, will be a significant driver of Vishay’s revenue, and any slowdown in EV adoption could impact demand.
