San Diego, Calif. Pulse, a Technitrol Company unveils five new series of unshielded and shielded surface mount technology (SMT) drum core power inductors for a total of 96 different parts. The inductors cover a wide range of inductance values from sub-microhenry up to hundreds of microhenries, at low rated currents, in a variety of sizes to meet a broad range of local DC/DC converter and filtering applications.
The new SMT drum core power inductors include three new series PF0504, PF0508 and PF0581 of unshielded power inductors series, and two new series PF0601 and PF0560 of shielded inductors.
The PF0504 series is available in 15 values from 0.68 (μH) (20 A) to 150 μH (2 Amps). It's packaged in a 0.73 x 0.6 x 0.45 in. footprint. Click here for the PF0504 series datasheet.
Housed in a 0.185 x 0.165 x 0.137 inch package, the PF0580 unshielded inductors offer 22 values from 1 μH (3.1 A) to 65 μH (0.41 A). Click here for the PF0580 datasheet.
The PF0581 unshielded power inductor series supplies 22 values from 10 μH (2.5 A) to 560 μH (0.32 A). The package size measures 0.406 x 0.367 x 0.174 inch. Click here for the PF0581 datasheet.
The PF0601 shielded power inductor series, with a 0.272 x 0.256 x 0.118 inch footprint, provides 22 values from 2.9 μH (2 A) to 330 μH (0.19 A). Click here for the PF0601 series.
Measuring 0.409 x 0.406 x 0.157 inch, the PF0560 shielded power inductor series offers 15 values from 1.5 μH (6.5 A) to 330 μH (0.52 A). Click here for the PF0560 series.
Both the new unshielded and shielded drum inductors have been designed to work in an ambient temperature range of -40°C to 125°C. The electrical characteristics provided are for an ambient temperature of 25°C. This operating temperature range is important because in certain applications, such as portable products with small enclosures, the temperature at which the equipment is exposed can change significantly, said the company.

All parts in these series are RoHS compliant and can support a peak reflow soldering temperature of 260°C. They also meet UL94 V0 standards.
Available in trays or tape-and-reel packaging, pricing for the new inductors ranges between $0.10 and $0.20, depending on the part and quantity. Delivery is six to eight weeks.
