CDE Cornell Dubilier SPA series ultra-low ESR solid polymer aluminum capacitors feature ultra-low ESR, high ripple current, long life, stable impedance and ESR, and are widely used in motherboard bypass, switching power supply input/output filters, power supply decoupling, laptop LCD displays, automotive digital equipment, and portable electronic equipment.
The SPA series solid‑polymer aluminum SMT capacitors from CDE are designed for high‑frequency filtering, power‑supply decoupling, and bulk storage in applications such as motherboards, switching supplies, laptops, automotive digital equipment and portable electronics. They feature ultra‑low ESR (5 mΩ‑9 mΩ @100 kHz), high ripple current capability (up to 4 A rms @100 kHz) and long life without dry‑out failure mechanisms.
The data sheet provides detailed specifications including operating temperature, rated voltage, surge voltage, capacitance range, tolerance, dissipation factor, ESR, leakage current and load life. It also lists part numbers, markings, packaging codes, and ordering information for tape‑and‑reel supply.
