Axial Leaded Capacitor, AVX TWD DCUltraMax series wet tantalum supercapacitor, designed for DC (holding) and low frequency pulse applications. TWD capacitors use high CV tantalum powder to achieve ultra-high capacitance values ??similar to the supercapacitor range, with other advantages, such as reflow soldering capability and extended temperature range up to 85C. The company said that wet tantalum designs make these capacitors suitable for applications with high reliability requirements.
