Vishay Intertechnology Expands 299 PHL-4TSI Capacitor Series with Higher Voltage Options
Vishay Intertechnology: The expansion of Vishay’s 299 PHL-4TSI series with higher voltage options offers designers increased flexibility
Vishay Intertechnology, Inc. has announced the expansion of its 299 PHL-4TSI snap-in, four-terminal aluminum electrolytic capacitor family by introducing new 350 V, 500 V, 550 V, and 600 V rated models. These additions offer a wider selection of capacitance-voltage combinations, giving engineers greater flexibility in designing power supplies, inverters for industrial applications, and home appliances. The 299 PHL-4TSI series aims to reduce component counts, lower costs, and increase the mechanical stability and longevity of end products.
Key Features and Benefits
The 299 PHL-4TSI capacitors feature a cylindrical aluminum case with pressure relief and are insulated with a blue sleeve. These devices are designed to operate reliably at temperatures up to 105°C, with a lifespan exceeding 5000 hours, even under high ripple current conditions. Ripple current ratings range from 1.9 A to 7.6 A, enabling designers to meet application requirements with fewer components, improving efficiency and reducing assembly complexity.
The series offers larger can sizes than typical two-terminal snap-in capacitors, ranging from 35 mm x 50 mm to 45 mm x 100 mm. This design feature allows the 299 PHL-4TSI series to replace multiple large screw-terminal capacitors, often connected by bus bars, with smaller components mounted directly to PCBs. This transition to soldered connections minimizes construction costs by eliminating the need for manual mounting.
Enhanced Performance and Mechanical Stability
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 299 PHL-4TSI series is well-suited for smoothing, filtering, and energy storage applications. The four-terminal configuration offers several advantages, including:
- Increased mechanical stability
- Keyed polarity, preventing incorrect installation
- Improved performance in high-vibration environments
These capacitors also comply with RoHS and REACH standards, ensuring environmental and regulatory compliance.
Streamlined Production and Availability
With the enhanced design of the 299 PHL-4TSI capacitors, manufacturers can now reduce component complexity while benefiting from cost-efficient PCB-mounted solutions. Production quantities are available with an 18-week lead time, and samples can be requested in small quantities from catalog distributors.
Conclusion
The expansion of Vishay’s 299 PHL-4TSI series with higher voltage options offers designers increased flexibility for a wide range of applications, including industrial power supplies and appliance inverters. By combining high ripple current ratings, long operational lifespans, and improved mechanical stability, these capacitors provide a cost-effective solution for enhanced performance and reliability.
