As more electronic systems continue to be integrated into end applications we use every day, the need for capacitor technologies that deliver high reliability, long life, stable performance, low ESR and low cost continues to grow.
This is where polymer capacitors come into play. Panasonic is a leading manufacturer of Solid Polymer Aluminum Capacitors: SP-Caps and OS-CON, Tantalum Polymer Capacitor – POSCAP as well as Polymer Hybrid Aluminum Electrolytic Capacitor technologies and has extensive design-in expertise and experience.
SP-CAP™ Polymer Aluminum
Panasonic’s SP-Cap™ Polymer Aluminum Capacitors are the go-to product when it comes to the replacement of MLCCs. SP-CAPs are Surface-Mount (SMT) Capacitors that utilize a conductive polymer as their electrolyte material in a layered aluminum design. Primarily used as input and output Capacitors for DC/DC converters due to ultra-low ESR values, SP-Cap Capacitors are high voltage options with the ability to withstand high reflow temperatures.
Another MLCC replacement go-to, Panasonic POSCAP™ capacitors feature stable capacitance at high frequency and temperature with low-ESR/ESL. POSCAP™ utilizes a sintered tantalum anode with a proprietary high-conductivity polymer cathode. POSCAP™ Capacitors are available in various, compact package sizes for a small PCB footprint while offering high volumetric efficiency for capacitance.
Available in both surface-mount and through hole types, Panasonic's OS-CON™ Aluminum-Polymer Solid Capacitors are utilize aluminum and a highly conductive polymer material to offer low ESR, excellent noise reduction and ripple current capabilities. The OS-CON™ Series parts are known for long-life and minimal ESR changes throughout the entire product line’s rated temperature range.
Polymer Hybrid Aluminum Electrolytic
These Panasonic capacitors combine the benefits of aluminum electrolytic and specialty polymer capacitors, offering a capacitor featuring high endurance, low-ESR, high tolerance for ripple current, inrush currents and elevated temperature. Hybrid capacitors are compact options known for their stable electric characteristics at high frequencies while maximizing reliability.
Panasonic surface mount film capacitors offer stable capacitance and temperature characteristics, tight tolerances, low ESR, low dissipation factors, no shock noise, no piezoelectric effect and no audible noise. Surface mount film capacitor applications include DC blocking and filtering, PLL, audio, DC/DC converter and back lighting.
