Vishay Intertechnology, Inc. (NYSE: VSH) has recently expanded its range of high-capacity, high-voltage molded tantalum capacitors by introducing a new W form factor (EIA 7316). This latest addition to the TR3 series offers improved performance and flexibility for engineers working on advanced electronic systems.

The W form factor measures 7.3mm x 6.0mm with a height of 3.45mm, providing a larger footprint compared to previous A to E form factors. This enables higher capacitance and voltage ratings, making it ideal for applications that demand greater power handling and stability. The expansion follows the recent launch of 63V and 75V tantalum capacitors, reinforcing Vishay's dedication to delivering cutting-edge components with superior reliability and performance.

This new W-shaped capacitor is designed to help engineers reduce component count in their designs. Previously, multiple capacitors had to be used in parallel to achieve the necessary energy storage capacity. By using the W form factor, designers can simplify their layouts, save board space, lower costs, and improve system reliability—especially in critical areas like communications base stations, data centers, industrial computing, automotive systems, military equipment, and medical devices.

Vishay’s molded tantalum capacitors are engineered to meet the growing demands of various industries. They are particularly well-suited for applications such as DC/DC output filtering on high-density PCBs or low-voltage distributed power systems. Their compact design and high performance make them a preferred choice for modern electronics.

The low-ESR TR3 W form factor is RoHS compliant and compatible with both high-speed automated and manual pick-and-place equipment. It also withstands lead-free reflow soldering processes, ensuring compatibility with modern manufacturing standards.

Sample units of the W-form factor low-ESR TR3 molded tantalum capacitors are now available, with full-scale production expected to begin in the second quarter of 2011. For major orders, the lead time is approximately eight weeks, allowing manufacturers to plan their supply chains accordingly.
