SMT Power Inductors use ferrite core material.
Press Release Summary:
Offered in sizes from 7.6 x 7.4 x 6.4 mm to 21.7 x 21.5 x 12.5 mm, Round-Wire Coil Surface Mount Power Inductors range from 0.3–50 µH with current rating up to 70 A. Models PG0871NL, PG0702NL, PG0926NL, PH0936NL, and PG1083NL have unconnected third pin that distributes weight and balances 3 terminals during mechanical vibration. Flattened leads serve as pad, making coil self-leaded. Inductors are used as energy storage devices and filters in POL regulators and as DC/DC converter output inductors.
Original Press Release:
Pulse Electronics Expands Range of Low-loss, High-saturation, Round-wire Coil SMT Power Inductors
~ Provide high efficiency inductor solutions with tight DCR tolerance and no thermal aging ~
San Diego, Calif. - Pulse Electronics Corporation (NYSE: PULS), a leading provider of electronic components, expands 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 6.4mm up to 21.7 x 21.5 x 12.5mm are now available with an inductance range from 0.3uH to 50uH and with a current rating up to 70A. These inductors use a ferrite core material which 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.
"Because ferrite material is immune to thermal aging, these inductors are more reliable and better performing at higher temperatures and frequencies than non-ferrite core inductors," said Gerard Healy, field applications engineer, Pulse Electronics Power Division. "The properties of ferrite material are more appropriate to the typical requirement of a DC/DC converter inductor, and using round wire instead of a flat coil results in a 25% cost reduction."
These inductors are used 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 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 minimizing the cost. The smaller packages are size compatible with industry-standard flat-coil inductors on the market (including the Pulse PG0426NL, PG0255NL, and PG0277NL series) commonly referred to as the 2525 series (quarter inch by quarter inch), 4040 series (0.4 x 0.4 inch) and 5050 series (0.5 x 0.5 inch) flat-coil inductors. The larger sizes satisfy the needs for emerging higher power (current) PSUs where industry standard platforms are currently lacking.
Pulse's RWCs are RoHS compliant and meet standard EIA481 requirements. They are available in tape-and-reel packaging. Lead time is eight weeks. The price ranges from $0.49 to $0.99 in quantities of 50,000 pieces. Pricing varies according to order configuration and destination.
