Below is a detailed breakdown of the most common types of supercapacitors, their technical characteristics, and typical bulk pricing per farad—ideal for engineers, procurement specialists, and product designers evaluating cost-performance trade-offs. . The costs of supercapacitors are tabulated in this data-file, with a typical system storing 15-seconds of electricity, for a capex cost around $10,000/kWh of energy but just $40/kW of power. Hence, for short-duration, but very frequent and fast-acting voltage regulation, supercapacitors may be. . Pricing (USD) Filter the results in the table by unit price based on your quantity. A tariff of 55 % may be applied if shipping to the United States. . Electric double layer capacitors and supercapacitors are a class of electrolytic (polarized) capacitors that offer exceptionally high capacitance values in relation to their physical size and low voltage ratings; individual devices have ratings of a few volts at most, though products incorporating. . Check each product page for other buying options. Need help? . The price of a supercapacitor depends on several factors including type, capacitance (farads), voltage rating, materials used, and application-specific design. Capacitor prices exhibit a wide range, primarily influenced by the capacitor's material, capacitance, voltage. .
