New case size & codes for automotive-grade ultralow-ESR tantalum capacitors
TRM Professional Series multianode, ultralow-ESR tantalum capacitors now come in new “U” case (EIA Metric 7361-43), thereby extending the range with several new ratings designed to address the demands of an ever-expanding scope of high-reliability automotive, military, medical, aerospace, and industrial applications. These volumetrically efficient surface-mount, J-lead capacitors are now available in “U” case, “E” […]
Low-pass integrated thin film SMD filters work at up to 4 GHz
The LP Series of 0805 high-performance, low-pass integrated thin film (ITF) SMD filters are now available in 700, 750, 780, 942, 1000, 1250, 1800, 1900, 2400, 2900, 3500, and 4000 MHz variants. The 0805 filters are compact and low-profile — measuring just 2.03 x 1.55 x 0.80 mm ±0.10 mm (l x w x h) […]
Spice models help design with automotive varistors
AVX Corporation has released new SPICE models for its CapGuard™ Automotive and TransGuard Automotive Series multilayer varistors. Designed to enable shorter, more cost-effective development cycles with more first-pass prototype successes, SPICE models allow electronic design engineers to quickly, easily, and effectively evaluate the integrity of circuit designs, accurately simulate their performance, and identify and correct potentially […]
Hermetic high-temperature SMD tantalum capacitors get a longer lifetime
AVX Corporation has doubled the lifetime of select THH 230ºC Hermetic Series high-temperature SMD tantalum capacitors. Four of the six ratings currently available now offer 2,000-hour lifetimes at 230ºC and 0.5VR, and all six recently completed mechanical shock and vibration testing to MIL-STD-202 at 230ºC with 20g peak, ensuring robust, high-reliability performance in harsh, extreme application […]
Series-connected supercaps sport low leakage, low ESR
AVX Corporation has released a new series of supercapacitor modules. Comprised of series-connected cylindrical, electrochemical, double-layer supercapacitors, the new SCM Series supercapacitor modules are currently available in two voltage ratings (5V and 5.4V), and exhibit optimal pulse power handling characteristics, including: high capacitance values (0.47F – 7.5F ±20% tolerance), low ESR (4mΩ – 300mΩ at 1,000KHz), […]
