This document introduces the specifications and characteristics of the SPA Solid Polymer Aluminum SMT Capacitors from Cornell Dubilier (CDE). These capacitors feature ultra-low equivalent series resistance (ESR), high ripple current, long life, stable impedance and ESR vs. temperature, and are great for applications such as motherboard by-pass switching, power supply input/output filters, power supply decoupling, high frequency noise reduction, laptop LCD displays, automotive digital equipment, and portable electronic equipment.
The SPA Solid Polymer Aluminum SMT Capacitor series from Cornell Dubilier is designed for high‑frequency applications such as motherboard bypass, power‑supply filtering, and automotive digital equipment. The capacitors feature ultra‑low ESR (5‑9 mΩ at 100 kHz), high ripple current capability (up to 4 A rms at 100 kHz), and a long life without dry‑out failure mechanisms.
The datasheet lists detailed electrical characteristics, temperature range, and mechanical dimensions, along with part numbers, packaging codes, and ordering information. It also includes a ratings table that shows ESR, ripple current, and maximum case dimensions for each voltage and capacitance option.
