MLCC Replacement Solutions

KEMET KOCAP Tantalum Polymer Capacitors are ideal for board space savings, a piezo noise-free environment, high capacitance, long stable life performance, and/or lower profile requirements. Tantalum polymer capacitors are selected over other capacitor technologies when application voltages are less than 50V, capacitance needs are between 1µF to 1mF, and application frequencies are below 1MHz. Since replacing ceramic capacitors with tantalum polymer capacitors is not typically one-for-one, designers need to consider several design requirements as outlined in the schematic below.
