1、TANTALUM CHIP CAPACITORS KEMETs family of solid tantalum chip capacitors is designed and manufactured with the demanding requirements of surface mount technology in mind. These devices extend the advantages of solid tan- talum technology to todays surface mount circuit applications. Complementing mu
2、ltilayer ceramic chip convenience with capacitance ratings through 1500 F, tantalum chip capacitors permit circuitdesigners to take full advantage of the benefits of surface mount technology. T491 Series Industrial The leading choice in todays surface mount designs is the KEMET T491 Series. This pro
3、duct meets or exceeds the requirements of EIA standard 535BAAC. The physical outline and dimensions of this series conform to this global standard. Five low profile case sizes are available in the T491 family. The R/2012-12, S/3216-12 and T/3528-12 case sizes have a maximum height of 1.2 mm. The U/6
4、032-15 size has a maximum height of 1.5 mm, and the V/7343-20 has a maximum height of 2.0 mm. This product was designed specifically for todays highly automated surface mount processes and equip- ment. This series uses the same proven solid tanta- lum KEMET technology acclaimed and respected through
5、out the world. Added to this is the latest in materials, processes and automation which result in a component unsurpassed worldwide in total perfor- mance and value. The standard terminations are 100% matte tin and provide excellent wetting characteristics and compatibil- ity with todays surface mou
6、nt solder systems. Tin-Lead (SnPb) terminations are available upon request for any part number. Gold-plated terminations are also available for use with conductive epoxy attachment processes. The symmetrical terminations offer total compliancy to provide the thermal and mechanical stress relief requ
7、ired in todays technology. Lead frame attachments to the tantalum pellet are made via a microprocessor- controlled welding operation, and a high temperature silver epoxy adhesive system. Standard packaging of these devices is tape and reel in accordance with EIA 481-1. This system pro- vides perfect
8、 compatibility with all tape-fed placement units. T492 Series Military KEMET is approved to MIL-PRF-55365/8 (CWR11), Weibull failure rate “B” level or 0.1% fail- ures per 1,000 hours, “C” level or 0.01% failures per 1,000 hours, and “D” level or 0.001% failures per 1,000 hours. This CWR11 product de
9、signated as KEMETs T492 Series is a precision-molded device, with compliant leadframe terminations and indelible laser marking. This is the military version of the global IEC/EIA standard represented by KEMETs T491 Series.Tape and reeling per EIA 481-1 is standard. T493 Series Military - COTS The T4
10、93 series is designed for the COTS (Commercial-Off-The-Shelf) requirements of military/aerospace applications. This series is a sur- face mount tantalum product offering various lead- frame surface finishes, Weibull grading and surge cur- rent testing options. The full part number includes a code de
11、fining the terminations, the Weibull reliability, surge test conditions, and the ESR range. The possi- ble terminations include gold plated, hot solder dipped, solder plated, and solder fused. Reliability grading of B level (0.1%/kHours) and C level (0.01%/kHours) are available. Surge current testin
12、g options include: 10 cycles at 25C, or 10-cycles at -55C and +85C. Both standard and low ESR options are available. All lots of this series are conditioned with MIL-PRF-55365 Group A testing. T494 Series Low ESR, Industrial Grade The T494 is a low ESR series that is available in all the same case s
13、izes and CV ratings as the popular T491 series. The T494 offers low ESR performance with the economy of an industrial grade device. This series is targeted for output filtering and other applica- tions that may benefit from improved efficiency due to low ESR. T495 Series Low ESR, Surge Robust The lo
14、w ESR, surge robust T495 series is an impor- tant member of KEMETs tantalum chip family. Designed primarily for output filtering in switch-mode power supplies and DC-to-DC converters, the standard CV T495 values are also an excellent choice for battery- to-ground input filter applications. This seri
15、es builds upon proven technology used for industrial grade tantalum chip capacitors to offer sev- eral important advantages: very low ESR, high ripple current capability, excellent capacitance stability, plus improved ability to withstand high inrush currents. These benefits are achieved through a c
16、ombination of proprietary design, material, and process parameters, as well as high-stress, low impedance electrical con- ditioning performed prior to screening. Capacitance values range from 4.7F to 1000F, in voltage ratings from 2.5 to 50 volts. T496 Series Fused KEMET also offers a “fail-safe” fu
17、sed solid tantalum chip capacitor. The built-in fuse element provides excellent protection from damaging short circuit condi- tions in applications where high fault currents exist. Protection from costly circuit damage due to reversed installation is offered with this device. Package sizes include the EIA standard 3528-12, 6032-15, 7343-31, and 7343-43 case size. Capacitance values range from 0.15 F to 470.0 F, in voltage ratings from 4 to 50. Standard capacitance tolerances include 20% and 10%. Tape and reeling per EIA 481-1 is standard. PRODUCT DESCRIPTION
