CDE SPA series solid polymer aluminum electrolytic capacitors have ultra-low ESR, high ripple current, long life, stable impedance and ESR vs. temperature, widely used in motherboard bypass, switching power supply input/output filters, power supply decoupling, high frequency noise reduction, laptop LCD display, automotive digital equipment, portable electronic equipment etc.
The SPA solid polymer aluminum SMT capacitors are designed for high‑frequency applications such as motherboard bypass, switching‑supply filters, power‑supply decoupling, laptop LCD displays, automotive digital equipment, and portable electronics. Their ultra‑low ESR and high ripple‑current capability make them suitable for bulk storage and ripple‑filtering tasks.
The datasheet lists operating temperature ranges, rated voltages, capacitance values, ESR, ripple current, and other key parameters, together with part numbers, packaging codes, and ordering information for each voltage and capacitance option.
