NIC Components Corp. (Melville, NY) introduced an improved version of its NSP solid-aluminum-electrolytic capacitors. The new line targets output-filter circuits for low-voltage and high-current dc/dc converters, switching power supplies, and voltage regulators.
The surface-mount, specialty-polymer, solid-electrolyte caps feature ultra-low equivalent series resistance (ESR) and high-ripple current ratings at high frequencies. An expanded capacitance range and improvements in ESR and ripple-current ratings is also included. The new capacitance is 2.2µF to 390µF with voltage ratings from 2Vdc to 16Vdc. The 100kHz ESR specs have been reduced to 0.012 ohm, and the ripple current ratings have been increased to 3,000mA(rms) (100kHz, 105 degrees C).
The new parts, in a standard D case, are priced at $0.55 to $2.20 each in production quantities. Lead time is 6 to 10 weeks.
