Set Analysis Service

The set analysis service examines designs that use tantalum and aluminum electrolytic capacitors and helps customers select replacement multilayer ceramic capacitors (MLCCs). The basic procedure begins with characterizing the circuit board and taking a complete inventory from the bill of materials, as well as verification of capacitance, actual operating voltage, and other critical parameters. Once the targeted capacitors are identified, analysis is performed on one component. The original capacitor is then replaced with an MLCC, and the performance is measured. Several MLCC values will be tested to find the capacitance value that offers the best performance and cost-effectiveness.
