Product Description
Product Overview
The TDK Electronics B40940 series are hybrid polymer aluminum electrolytic capacitors designed for high-reliability applications requiring very high ripple current capability and extended operational life at elevated temperatures. These SMD capacitors offer miniaturized dimensions, long useful life (4000 h at 135 C), and a high operating temperature capability up to 145 C. They are suitable for demanding applications in automotive and industrial electronics, featuring very low ESR across the temperature range and compatibility with reflow soldering.
