T545 KO-CAP Polymer Pulse Capacitors KEMET T545 KO-CAP Polymer Pulse Capacitors are designed for high energy storage at low voltages (<,20V). This capability makes the T545 ideal for applications requiring relatively long hold-up times, including data hardening common in volatile memory systems such as Solid State Drives (SSDs) and embedded microprocessor systems. KEMET T545 KO-CAP Polymer Pulse Capacitors use organic polymer technology to provide high capacitance, low ESR, and high volumetric efficiency. The devices provide a long usable lifespan at industrial temperatures.
