F-3114C 1/08 KEMET is now on the QPL list for Switch Mode Power Supply (SMPS) Military Stacked Capacitors with MIL-PRF-49470 standard B Level reliability availability. These devices are intended for high reliability SMPS and pulse energy applications. Their low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL) make them ideally suited for input and output filtering of power supply applications as well as snubber applications. The multilayer construction also creates high thermal transfer functions, resulting in very little temperature rise for the generated power giving the capacitors excellent high current handling capability. The performance benefits of ceramic are being realized in many applications that were heretofore unavailable to these capacitors. The replacement of larger capacitance electrolytic capacitors with smaller value ceramics is a common occurrence today, but there are still some larger capacitance values required of the MLCC. The capacitors are constructed using large chip sizes, much larger than those available for standard surface-mount applications. Because they are so contact to the board is through a pin structure. The pin structure located at the bottom of the leadframe consists of multiple pins at 100 mil centers. The formation of these pins can be surface mountable styles "L" and "J" (or gull-wing), or as throughhole insertion pins style "N." This multi-pin arrangement allows the extremely low ESR and ESL of the chip package to be presented to the circuit without any significant increases. This arrangement also allows a very efficient thermal transfer path to exist between the chip package and the PC board, as most of the thermal dissipation for this package will be through the leadframe connection. These capacitors are available in case codes 3, 4, & 5. They are available in X7R dielectric, in voltage ranges from 50 VDC to 500 VDC. The chip stack is horizontal and the leadframe attachment is a high-temperature solder. They are also available as unpotted bare chips or as a potted assembly. MIL-PRF-49470 and DSCC drawing 87106 (X7R) are used to establish a baseline part for high-reliability applications. MLC Chip Leadframe 'J' Form Leadframe large, mounting these devices directly to the PC board would more than likely generate cracking because of straight mechanical strain, or strain which occurs because of mismatches in CTE (coefficient of thermal expansion) between the board and the ceramic. This strain is proportional to the distance between the termination pads on the PC board and results in an increasing propensity for failure among the larger SMT chips. The leadframe is attached to the chip stack (from singular to multiple chips) and creates a mechanical relief between the ceramic device and the board, so they are not bound to each other. The contact to the chips is usually a perforated, vertical, metal plate while the 2 Capacitance values at 50 VDC are available up to 47 F (X7R). Care must be exercised when using the bare chips to ensure there can be no mechanical damage imposed on the mounted parts, although the potted devices reduce this potential dramatically. Larger Case codes 1, 2, & 6 will be available for order in Q3CY08. The T level high reliability space level version will be available in calendar year 2009. (c) KEMET Electronics Corporation * P.O.

The DSCC drawing 87106 has been cancelled ( h t t p : / / w w w. d s c c . d l a . m i l / D o w n l o a d s / MilSpec/DsccDwg/87106.pdf). However, KEMET is able to supply to the DSCC 87106 drawing per customer request. KEMET will supply to the DSCC 87106 drawing with an exception taken to performing Group B Inspections on a per lot basis. Per DSCC drawing section 4.2.2 the acquiring activity, at its discretion, may accept a certificate of compliance (CofC) with Group B inspections in lieu of performing Group B inspections. KEMET 87106 orders will include the CofC stating compliance to the 87106 requirements. KEMET's MILPRF-49470 QPL status confirms KEMET's compliance to the Group B testing requirements. The MIL-PRF-49470 capacitors are preferred over the DSCC drawing 87106 capacitors as outlined in NASA's Electronic Parts and Packaging website:http://nepp.nasa.gov/npsl/Capacitors/ 87106/87106aps.htm. The M49470 military specification product provides additional quality assurance provisions that are not required by the DSCC drawing. These extra provisions helped to create a more robust replacement for the 87106 capacitors.

Use MIL-PRF-49470 parts as a direct replacement. When available MIL-PRF-49470 SMPS capacitors are preferred over DSCC-DWG-87106 capacitors. The MIL-PRF-49470 specification was developed as part of a cooperative effort amongst the US Military, NASA and the SMPS suppliers to produce a robust replacement for the DSCC drawing. The MIL spec product provides additional quality assurance provisions which are NOT required by the DSCC drawing. Some of the benefits of the MIL-PRF-49470 product over the DSCC-DWG-87106 product include: Requirement MIL-PRF-49470 DSCC-DWG-87106 Formal Qualification Process (QPL Established) Yes No MIL-STD-790 Compliance Yes No DSCC Audits Yes No Routine Qualification Maintenance Testing (ie., Life Testing) Yes No Group A Percent Defective Allowed (PDA) Specified Yes No Prohibits Mixing of Chips from Different Production Lots within a Single SMPS Stack Lot Yes No SOLDERING RECOMMENDATIONS FOR CERAMIC STACKED CAPACITORS Ceramic stacked capacitors are large mass devices and much care should be taken when soldering these capacitors. For this reason, hand soldering is not a recommended soldering method for these devices. Following the proper soldering guidelines is critical in order to prevent thermal cracking. PRE-HEATING AND REFLOW PROFILE Due to differences in the coefficient of thermal expansion for the different materials of construction it is critical to monitor and control the heating and cooling rates during the soldering process. During the reflow soldering process, the maximum recommended heating and cooling rate (dT/dt) is 4C/second. To ensure optimal component reliability, KEMET's recommended heating and cooling rate is =2C/second. After soldering, the capacitors should be air cooled to room temperature before further processing. Forced air cooling is not recommended.
