CORNELL DUBILIER SPA CapacitorsSolid Polymer Aluminum Surface Mount Capacitors Picture Highlights • Capacitance Range: 2.2 µF to 390 µF • Ripple current ratings up to 3.5Arms at 100 kHz and 105ºC • Low Impedance Ω @ 100 kHz • Ultra-Low E.S.R.; 10 mΩ • -55º to 105ºC operating temperature • Voltage Range: 2.0 Vdc to 16 Vdc • Solid electrolyte for extended life • Footprint Compatible with “D” and “E” Case Tantalum • Flat Z and E.S.R. vs. temperature • Ignition free Filtering power of 3 or more tantalum chips and 50 year life Solid polymer aluminum capacitors combine the high capacitance capability of an electrolytic component with the high frequency performance of film capacitors. When the need for low impedance at high frequency is critical for your design, one SPA chip is capable of replacing several liquid electrolyte aluminum or tantalum capacitors connected in parallel. This is due to the ultra-low e.s.r. which results in significantly lower impedance than either aluminum or tantalum capacitors at frequencies of 100 kHz and above. There is no longer a need to stack capacitors to lower the impedance at high frequency. The low e.s.r. and high capacitance make them ideal for bypassing high frequency noise, and for switching frequency filtering in DC/ DC conversion. SPA capacitors are packaged in a molded resin case with the same footprint (7.3x4.3 mm) as the industry standard tantalum “D” and “E” case sizes. The solid electrolyte results in a capacitor with stable impedance and equivalent series resistance over the entire operating temperature range and they have more than twice the ripple current handling capability of tantalum capacitors. In addition, the solid electrolyte delivers a typical expected operating life of more than 50 years, and it is ignition free.

Exceeding the specified maximum ripple current will overheat and damage the capacitor. The maximum ripple current ratings are given in the ratings tables. Solid polymer aluminum capacitors are quite rugged and may be operated continuously at rated voltage. Voltage derating does not significantly increase the life expectancy of the capacitor. At voltage levels equal to or less than rated voltage, the capacitor will not short circuit (even at end of life). In fact it can self heal. A polymer aluminum capacitor can be operated over a lifetime at full rated voltage without worry of short circuiting. However, if subjected to sufficient over voltage or reverse voltage, a SPA capacitor can fail short circuit. Peaks of the AC ripple voltage should not exceed the rated voltage or cause voltage reversal. Reverse Voltage SPA capacitors are polarized and are not intended to be used with reversed voltage. They can withstand reverse voltage pulses or transients up to 20% of the rated voltage, and they are capable of operating with up to 10% of the rated voltage when reverse voltage is applied continuously. Shelf Life When stored at room temperature, in low humidity, and out of direct sunlight, SPA capacitors Ripple Current/Ripple Voltage AC voltage as part of the capacitor’s DC bias have a storage life of 5 to 10 years. Storage at high voltage will cause current to flow through the humidity over long periods of time can cause the capacitor. This ripple current flows through the DC leakage current to increase. However, the apcapacitor’s equivalent series resistance generating plication of rated voltage will reduce the DC leakheat. The heat increases the capacitor’s internal age current to normal limits.

Capacitors suspected of having been exposed to high humidity can be reclaimed by placing them in an oven at 50°C for 100 Hours. Reflow Soldering The following graph gives the maximum recommended capacitor surface temperature during reflow soldering. Heat Stress while Soldering DC leakage current can increase after soldering, but it will return to the initial level after applying voltage. When using a soldering iron to mount the capacitor, the iron should have a maximum temperature of 350ºC and soldering should not exceed 10 seconds.

They have reliability advantages over both aluminum and solid tantalum electrolytic capacitors. Unlike aluminum capacitors, there is no liquid electrolyte that can evaporate and cause a failure. Unlike solid tantalum which can fail short and burn, SPA capacitors gradually become open circuits after 25 to 50 years operation. Life expectancy curves show 200,000 hours expected life at full rated voltage and normal ambient conditions. Ultra Low E.S.R. and High Ripple Current Capability The equivalent series resistance (e.s.r.) of solid polymer aluminum capacitors is much lower than the e.s.r. of solid tantalum capacitors. This results in a much higher ripple current handling capability. The e.s.r. is even lower than the new tantalumpolymer hybrid capacitors. SPA’s ultra-low resistance magic is in the solid conductive polymer. The series resistance of electrolytic capacitors is largely determined by the resistivity of the electrolyte. Because the resistivity of SPA’s polymer electrolyte is several orders of magnitude less than that of other electrolytes, the equivalent series resistance is almost zero. Construction Construction is a unique combination of the elements of aluminum electrolytic and solid tantalum capacitors. A highly conductive polymer electrolyte film is deposited over the aluminum oxide dielectric in SPA capacitors. Carbon and silver paint are used to finish the capacitor’s cathode. This is similar to Like conventional aluminum electrolytic capacitors, what is used in solid tantalum capacitors, where the anode in SPA capacitors is an aluminum plate manganese dioxide is used as the electrolyte. on which an aluminum oxide layer has been built up by an electrolysis process.

The terminals are solder coated copper clad steel. The dielectric in solid tantalum capacitors is tantalum pentoxide which is built upon a tantalum pellet anode. 1605 East Rodney French Boulevard New Bedford, MA 02744 Phone: (508) 996-8564, FAX (508) 996-3830 http://www.cornell-dubilier.com E-mail:[email protected] 1.041 SPA Capacitors Solid Polymer Aluminum Capacitors SPA Compared to Other Electrolytics 1000 10 µF 100 Aluminum Electrolytic Impedance (Ohms) 10 Tantalum Electrolytic 1 0.1 Film 0.01 SPA 0.001 0.0001 0.001 0.01 0.1 1 10 100 Frequency (MHz) SPA capacitors have lower impedance at high frequencies than the same values of wet electrolyte aluminum capacitors and solid tantalum capacitors. 1.6 10 µF @ 1 MHz 1.4 Aluminum Electrolytic Impedance (ohms) 1.2 1 Tantalum Electrolytic 0.8 0.6 0.4 0.2 SPA 0 -60 -40 -20 0 20 40 Temperature (ºC) 60 80 100 120 SPA capacitors have stable impedance over the entire temperature range. 1.042 1605 East Rodney French Boulevard New Bedford, MA 02744 Phone: (508) 996-8564, FAX (508) 996-3830 http://www.cornell-dubilier.com E-mail:[email protected] SPA Capacitors Solid Polymer Aluminum Capacitors SPA vs Solid Tantalum 10 SPA 10uF/6.3Vdc 7.3x4.3x1.8mm Tantalum 100uF/6.3Vdc 7.3x4.3x2.8mm e.s.r.
