Kemet Corp. has expanded its small case size low ESR solutions with the addition of three new B Case (3528-21) offerings available with maximum ESR values of 25m次.

The new devices are the latest addition to Kemet's 25m次 B Case offerings, which now include voltage ratings from 2.5V to 10V with capacitance offerings from 33?F to 220?F. The 25m次 B Case offerings are suitable for portable electronics and offer other industry segments a small case size substitution option for larger low ESR D Case (7343-31) and V Case (7343-20) offerings.

Kemet has also extended the T498 high temperature (150∼C) Series with the introduction of two high CV offerings. The T498C226_016 boasts the highest capacitance available in a high temperature 16V C Case (6032-28) size with a capacitance value of 22?F and a maximum ESR rating of 1600m次, said Kemet. The T498D226_035 offers 22?F of capacitance in a 35V design with an industry leading ESR limit of 700m次. This D Case (7343-31) offering also represents the highest CV rating available in this configuration. The T498 series was designed to deliver stable and reliable performance in extreme temperature applications such as automotive under-the-hood applications and oil exploration.

The devices are capable of meeting 3x reflow at the higher temperature (260∼C peak) Pb-free profiles.
