Vishay Intertechnology’s latest surface-mount Hi-Rel COTS series of solid tantalum chip capacitors combines Weibull grading and surge-current test options per MIL PRF 55365, a low-ESR option, and built-in fuses for high reliability and protection against short circuits in critical applications.
The T86 series devices feature an internal fusing mechanism that activates at + 25 °C for 0.1 s with a 5A minimum applied current. In the event of a failure due to excessive current flow, this fusing prevents damage to circuit components in high-reliability avionics and military applications.
The option of low ESR values, which extend down to 0.25 Ω at + 25 °C and 100 kHz, allows for more efficient filtering in applications requiring maximum reliability, such as safety-critical industrial applications, medical instrumentation, and diagnostic, high-end computing and data storage. The capacitors' high ripple current handling capability ensures stable output voltages.
The devices released today, part of Vishay's Tantamount tantalum capacitor family, are offered in the C, D, E molded case sizes and have a capacitance range of 0.47 μF to 470 μF and voltage range from 4 V to 50 V. Their extended capacitance/voltage values, coupled with reliability, surge current, and ESR options, make the T86 tantalum capacitors a flexible solution for a wide variety of application and performance requirements.
Compatible with high-volume automatic pick-and-place equipment, the T86 series features standard RoHS-compliant tin terminations, with Sn/Pb terminations available. The capacitors operate over a temperature range of – 55 °C to + 125 °C. Lead times is 10 to 12 weeks.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
