San Diego, Calif. Pulse, a Technitrol Company, has introduced the PG0702NL series of flat-coil surface-mount (SMT) power inductors. These inductors offer a low direct current of resistance (DCR) of 0.89 to 5.9 milliohms and a tight tolerance of +/-6 percent for higher efficiency.
The PG0702NL power inductors provide inductance values from 0.40 to 3.0 microhenries with a peak saturation of 15 to 45 amperes (A). Operating frequency is 100 kHz to 1 MHz at an operating temperature of -40°C to 130°C with no thermal
derating. These inductors are used to store energy and serve as filters in voltage regulator modules (VRMs) used in notebook computers, desktop computers, workstations, and servers as well as dc/dc applications, point-of-load (POL) converters, and other high-density, high-power, high-ambient temperature applications.
The power inductor series uses a ferrite core material, which has one tenth the core loss of iron powder or iron alloy core materials. The lower core loss of the ferrite material is optimized at frequencies above 500 kHz. The decrease in core loss significantly increases
system efficiency five to ten percent, and because the ferrite material is immune to thermal aging, these inductors are reliable at higher operating temperatures, said Pulse.
Housed in an industry standard 4040 footprint of 10.8 x 9.5 x 8 millimeters, the PG0702NL incorporates a three-pin design for improved mechanical stability. An unconnected third pin at the back of the inductor distributes the part's weight and balance
between the three terminals during mechanical vibration. The series meets EIA481 requirements and is RoHS compliant.
Pricing: Starts at $0.25 in quantities of 500,000+. Individual part pricing may vary due to order configuration and shipping destination.
Availability: Lead time is four to six weeks.
