It is important to note that for most capacitors, ESR is speci- fied only at room temperature. However, the designer must ensure that the ESR will stay inside the limits shown over the entire operating temperature range for the design. For aluminum electrolytic capacitors, ESR will increase by about 30X as the temperature is reduced from 25'C to -40'C. This type of capacitor is not well-suited for low tem- perature operation. Solid tantalum capacitors have a more stable ESR over tem- perature, but are more expensive than aluminum electrolyt- ics. A cost-effective approach sometimes used is to parallel an aluminum electrolytic with a solid Tantalum, with the total capacitance split about 75/25% with the Aluminum being the larger value. lf two capacitors are paralleled, the effective ESR is the par- allel of the two individual values. The "flatter" ESR of the Tan- talum will keep the eective ESR from rising as quickly at low temperatures. |
