Surface Mount and Through-Hole Multilayer Ceramic Chip Stacked Capacitors KPS MIL Series, SMPS Stacked Capacitors, MIL-PRF-49470, DSCC 87106, 25 - 1,000 VDC (Commerical, Military and Space Grades) Overview KEMET Power Solutions (KPS) MIL Series ceramic stacked capacitors are available in commercial, military and space grades and are well suited for standard and high reliability switch mode power supply (SMPS) and pulse energy applications. Qualified under performance specification MIL-PRF-49470, our military and space grade products meet or exceed the requirements outlined by DSCC (Defense Supply Center, Columbus) and are available in both B (standard reliability) & T (high reliability) product levels. MIL-PRF-49470 was developed as part of a cooperative effort between the U.S. Military, NASA and SMPS suppliers to produce a robust replacement to cancelled DSCC Drawing 87106. using a high melting point (HMP) solder alloy. The lead frame isolates the MLCCs from the printed circuit board (PCB) while establishing a parallel circuit configuration. Mechanically isolating the capacitors from the PCB improves mechanical and thermal stress performance, while the parallel circuit configuration allows for bulk capacitance in the same or smaller design footprint. The KPS MIL Series is constructed using large chip multilayer ceramic capacitors (MLCCs), horizontally stacked and secured to a lead-frame termination system Available in BX, BR, BQ, and X7R dielectrics, these devices are available in encapsulated and unencapsulated styles in both surface mountable and through-hole configurations. Their low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL) make them ideally suited for input and output filtering of power supply as well as snubber applications. The encapsulated styles are primarily used where increased mechanical and environmental protection is required, such as in avionics systems.

Temperature profiles used should provide adequate temperature rise and cool-down time to prevent damage from thermal shock. In general, KEMET recommends against hand soldering for these types of large ceramic devices. Recommended Soldering Technique: * Solder reflow only Recommended Reflow Soldering Profile: TP Temperature TL tP Maximum Ramp Up Rate = 3C/sec Maximum Ramp Down Rate = 6C/sec tL Tsmax Tsmin 25 ts 25C to Peak Time Profile Feature Sn-Pb Assembly Preheat/Soak Temperature Minimum (TSmin) Temperature Maximum (TSmax) Time (ts) from Tsmin to Tsmax) Ramp-up rate (TL to TP) Liquidous temperature (TL) Time above liquidous (tL) Peak Temperature (TP) 100C 150C 60-90 seconds 2C/seconds 183C 95 seconds 240C Time within 5C of maximum peak temperature (tP) 5 seconds Ramp-down rate (TP to TL) Time 25 C to peak temperature 2C/seconds 3.5 minutes Note 1: All temperatures refer to the center of the package, measured on the package body surface that is facing up during assembly reflow Preheating and Reflow Profile Notes: 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. (c) KEMET Electronics Corporation * P.O.

The date code shall consist of the year and week. For example, the third week of 2011 would be 1103 using a 4-digit date code or 103 using a 3-digit date code. At the option of the manufacturer, the date code may be placed on a separate line. Full marking shall be included on the package. JT 12345 106K 1103 MIL-PRF-49470Case code 4 or 5 example Capacitor marking will include "JAN" or "J." Case codes 4 and 5 shall be marked with the following sequence of information: J brand (1 digit), product level designator ("B" or "T") Manufacturer's identification (1 to 5 digits) Capacitance code (3 digits) and capacitance tolerance (1 digit) Date code (3 or 4 digits) Case code 3 shall either be fully marked or partially marked like case code 4 or 5 parts at the option of KEMET. DSCC 87106 Marking shall be in accordance with MIL-STD-1285, except the parts shall be marked with the part number as specified in paragraph 1.2 of DSCC Drawing 87106 with the manufacturer's name or code and date code minimum. Case sizes 4 and 5 shall be marked with coded capacitance and tolerance minimum. Full marking shall be included on the package. Storage and Handling Ceramic chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be degraded by high temperature-reels may soften or warp and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40C and maximum storage humidity not exceed 70% relative humidity. Temperature fluctuations should be minimized to avoid condensation on the parts and atmospheres should be free of chlorine and sulfur bearing compounds. For optimized solderability chip stock should be used promptly, preferably within 1.5 years of receipt.

KEMET is qualified to supply MIL-PRF-49470/1 unencapsulated X7R Case Codes 3, 4, & 5 ceramic SMPS capacitors in DC voltage ratings of 50 V, 100 V, 200 V, and 500 V. This qualification includes both "B" and "T" test levels. KEMET is also qualified to supply MIL-PRF-49470/2 encapsulated X7R Case Codes 3, 4, & 5 ceramic SMPS capacitors in DC voltage ratings of 50 V, 100 V, 200 V, and 500 V. This qualification includes "B" level testing only. Notice of Cancellation: DSCC Drawing 87106 was cancelled on January 3rd 2005. MIL-PRF-49470 parts are preferred and direct replacements. MIL-PRF-49470 capacitors are preferred over DSCC 87106 capacitors. The MIL-PRF-49470 specification was developed as part of a cooperative effort between the U.S. Military, NASA and the switch mode power supply capacitor manufacturers to produce a robust direct replacement for the DSCC drawing. The military specification product provides additional quality assurance provisions that are NOT required by the DSCC drawing. Two product levels are offered in MIL-PRF-49470: the standard "B" level and the high reliability "T" level. Some of the benefits of the MIL-PRF-49470 product over the 87106 product include the following: Formal qualification process (QPL established), MIL-STD-790 compliance, DSCC audits, routine qualification maintenance testing, i.e., life testing, group A percent defective allowed (PDA) specified, and prohibiting the mixing of chips from different production lots within a single SMPS capacitor stack lot. MIL-PRF-49470 "T" Level product is recommended for all high reliability applications. MIL-PRF-49470 "T" level product requires the following in-process inspections and additional group A and B screening inspections that are not part of the normal "B" level flow: In-process screening that includes non-destructive internal examination (chip level) and destructive physical analysis (chip level), group A destructive physical analysis (finished stack level), group B lot specific humidity, steady-state, low voltage (lot sample test), and group B lot specific thermal shock and life test (lot sample test).
