AVX Corp. has launched a new series standard and custom supercapacitors designed for size, weight, and power (SWaP)-optimized, battery-powered products. The company claims the SCP Series PrizmaCap supercapacitors offer the widest operating temperature range (-55°C to 90°C), compared to competitive technology as well as the highest capacitance (3.5–15 F) and energy density (1.14–2.43 Wh/kg) compared to any small form factor (SFF), prismatic, electric double-layer capacitor (EDLC) rated for more than 1 F, currently available on the market.
In addition, the supercapacitors are housed in an extremely lightweight (<2 g) and low-profile form factor (0.8–2 mm) based on propylene carbonate electrolyte technology, which has been proven to be safe in energy storage applications including lithium-ion batteries, said AVX.
The supercaps are available in three standard form factors with a 48 x 45-mm footprint, three ultra-low-height profiles (0.8 mm, 1.3 mm, or 2.0 mm), and two fixed-position, surface-mount terminals compatible with hand soldering or AVX Interconnect’s 70-9159 Series STRIPT two-piece, single contacts.
The three standard solutions (SCPB08A355SNA, SCPB13A855SNA, and SCPB20A156SNA) are rated for up to 15 F, 2.1-V electrical potential from -55°C to 65°C, 8.63-A peak current, and 2.43 Wh/kg energy density. The devices claim the widest operating temperature range with appropriate derating to 1.1 V. Other specs include a maximum DCL as low as 50 μA after 72 hours of operation, a maximum ESR as low as 30 mΩ at 1 kHz and 55 mΩ at DC, and up to 2,582 W/kg power density and 0.0092 Wh maximum energy. Additional off-the-shelf solutions with standard footprints and capacitance values will be released as they are qualified.
Custom SCP Series PrizmaCap supercapacitors are available with customer-specified footprints and capacitance values ranging from 1–500 F.
The SCP Series PrizmaCap supercapacitors are RoHS- and REACH-compliant, lead-free compatible. They are tested for life cycle, high-temperature load life, temperature characteristics, vibration resistance, and humidity characteristics prior to being packaged and shipped in trays. Standard lead time for the series is currently 16 weeks.
