The Cornell Dubilier Type 300 and 301 series capacitors are designed for wide-temperature, low-ESR applications, particularly for power-supply outputs and UPS battery stiffening. Their exceptionally low Equivalent Series Resistance (ESR) enables high ripple-current capability. With low series inductance and high ripple current ratings, these capacitors can replace multiple standard capacitors, offering significant space and cost savings. Type 300 features three leads for robust, reverse-proof mounting, while Type 301 has two leads. The Type 300R and 301R variants offer even lower ESR and higher ripple current handling.
