Consider the Vishay TR3 low ESR product line. The TR3’s best-in-class ESR yields improved circuit electrical performance,
power efficiency, and reliability (lower operating temperatures). Based on case size, a number of capacitance / voltage (CV)
options are available and each combination has a specific ESR value (see Fig. 1 for the D case example).

In addition to ESR, designers must take voltage rating, ESL, DCL, and dielectric properties into consideration for filter capacitor
designs. Tantalum capacitors in general allow for very low profile and compact designs and enable high PCB-level reliability
due to their solid construction.
