Pulse Expands Series of Low-Loss, High-Saturation, Round-Wire Coil SMT Power Inductors

Provides high efficiency inductor solutions with tight DCR tolerance and no
thermal aging
SAN DIEGO--(Business Wire)--
Pulse, a Technitrol Company (NYSE: TNL), a worldwide leader in electronic
component and subassembly design and manufacturing, introduces the new PG0871NL
and PG0702NL series of round-wire coil surface mount power inductors. 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. Using round
wire instead of a flat coil results in a 25% cost reduction.

Pulse`s PG0871NL has a low direct current resistance (DCR) of 1.5 to 31.5
milliOhms (mΩ) with a tight tolerance of ± 8% and operates up to 130° Celsius
(C) without any thermal aging concerns. Inductance values range from 0.46 to
10.5 microHenries (uH) and saturation current from 6.3 to 28 Amperes (A). The
mechanical size is 7.6 x 7.4 x 6.4millimeters (mm).

Pulse`s PG0702NL has a low DCR of 0.68mΩ to 7.7mΩ with a tight tolerance of ± 6%
and like the PG0871NL, operates up to 130°C without any thermal aging concerns.
Inductance values range from 0.30uH to 6.8uH with saturation current from 8.5 to
42A. The mechanical size is 10.8 x 9.2 x 8mm.

Operating temperature ranges from -40°C to 130°C. These inductors are used as
energy storage devices and filters in point-of-load (POL), telecom, datacom,
server, and industrial dc-to-dc applications. They are a lower cost alternative
to flat coil inductors for applications where very low profile is not a
requirement.

Pulse`s PG0871NL and PG0702NL 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.

These packages are size compatible with industry-standard flat-coil inductors on
the market (including the Pulse PG0426NL and PG0255NL series) commonly referred
to as the 2525 series (quarter inch by quarter inch) and 4040 series (0.4 x 0.4
inch) flat-coil inductors.

Pulse`s PG0871NL and PG0702NL series are RoHS compliant and meet standard EIA481
requirements. They are available in tape-and-reel packaging. Lead time is eight
weeks. The price for the PG0871NL is $0.35 and the PG0702NL is $0.42 in
quantities of 50,000 pieces. Pricing may vary according order congifuration and
destination. Contact Pulse directly for volume pricing and samples. Detailed
specifications are available on datasheets P682
(http://ww2.pulseeng.com/products/datasheets/P682.pdf) and P667
