New supercapacitors to reduce battery surges Vishay’s new 4th generation EF series power MOSFET technology currently offers the industry’s lowest on-resistance of only 0,045&nsp O at 25☌ when compared to similar devices. Vishay has released its new surface-mount multilayer ceramic chip capacitors, which are available in custom frequency ranges. The components are RoHS-compatible and qualified to AEC-Q200.įurther reading: Surface-mount ceramic chip capacitors The new components can be used as output and storage chokes in a wide variety of power supply topologies including point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies and inverters for photovoltaics systems and automotive applications. Its additional third soldering pad results in high mechanical stability on the PCB. The new series of high-current chokes is designed for operating temperatures between -40☌ and +150☌. The DC resistances are between 1 mΩ and 15,4 mΩ.
This low-profile design is based on a flat rectangular helical winding technology, which also results in lower losses. The low insertion heights of 7,55 mm (1,0 µH) to 11,1 mm (30 µH) vary depending on the type. at 25☌.Ī key feature of these new power inductors is their compact design: with a footprint of just 17,3 x 16,5 mm, they take up 12% less space on the PCB than their predecessor. The inductance values of the new B82559B*A016 series, which replaces the former B82559A*A016 series, extend from 1,0 µH to 30 µH and their saturation currents range from 10,3 A d.c.
TDK has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of 10 different types.
