CoEv Magnetics Intros DZM Series Power Inductors

CoEv Magnetics, a unit of Tyco Electronics (Menlo Park, CA), announced its new DZM Series of lead-free power inductors. The low-voltage, high-current inductor is designed for switching power supplies and portable electronics.

The DZM inductors are free from thermal aging effects of standard iron powders, offer increased energy storage, are lead-free, and Reduction of Hazardous Substances compliant. The design of the DZM Series reduces failure modes often found with plating and solder-terminated wires and leads while minimizing contact resistance. The multi-gap technology used to manufacture the device also reduces fringing flux and stray field emissions. The core material is specially formulated to avoid thermal aging, minimize core loss, and provide a mean time between failures of greater than one million hours of operation.

The DZM inductor filters and smoothes ac ripple current in dc circuits utilizing a 200 °C insulation system, and is well suited for operating in environments with a -40 °C to +155 °C temperature range, such as laptops, power converters and portable electronics. The DZM Series, which is an extension of the DXM family, is designed to handle higher currents, up to 50 A, with inductance ranges of 0.10 µH to 3 µH, and are available in the same 13 mm x 13 mm x 6 mm package size as the DXM inductors.

Samples are available now. Pricing is $0.38 in quantities of 100,000 units, with delivery in four to six weeks ARO.
