Pulse Electronics has expanded its range of round-wire coil (RWC) surface mount power inductors to deliver higher inductance/current capability. Mechanical sizes from 7,6 x 7,4 x 6,4 mm up to 21,7 x 21,5 x 12,5 mm are now available with an inductance range from 0,3 μH to 50 μH and with a current rating up to 70 A.
These inductors use a ferrite core material which reportedly yields a 90% core loss reduction and 30% increase in maximum operating temperature when compared to standard iron powder material used in flat-coil inductors. Also, because ferrite material is immune to thermal ageing, these inductors are more reliable and perform better at higher temperatures and frequencies than non-ferrite core inductors.
The new components are aimed at use as energy storage devices and filters in point-of-load (POL) regulators and as DC-DC converter output inductors for telecom, datacom, server and industrial applications. They are a lower-cost alternative to flat coil inductors for applications where a very low profile is not a requirement.
The series consists of the PG0871NL, PG0702NL, PG0926NL, PH0936NL and PG1083NL. These inductors have a three-pin design for improved mechanical stability. An unconnected third pin at the back of the inductor distributes the part’s weight and balances the three terminals during mechanical vibration. Flattened leads serve as the pad, making the coil self-leaded. No additional base is required, further minimising the cost.
The smaller packages are size compatible with industry-standard flat-coil inductors on the market. The larger sizes satisfy the needs for emerging higher-power (current) PSUs where industry standard platforms are currently lacking.
