Pulse Debuts Round-Wire Coil Surface-Mount Power Inductors

By Shamila Janakiraman, TMCnet Contributor

Pulse, a Technitrol (News - Alert) Company specializing in electronic component and subassembly design and manufacturing, has announced the introduction of PG0871NL and PG0702NL – a series of round-wire coil surface-mount power inductors.

Officials with the company explained that these inductors use a ferrite core material which reduces core loss significantly and also allows for an increase in operating temperatures - this is better than standard iron powder material which is usually used in flat-coil inductors.

Ferrite material is not affected by aging due to heat – making these inductors reliable for use at higher temperatures and frequencies than non-iron core inductors. Also, according to officials, the use of a round wire in place of a flat coil reduces costs by 25 percent.

The new inductors from Pulse (News - Alert) also exhibit low direct current resistance (DCR) with tight tolerance and can operate at 130 degrees Celsius without being affected by heat.

In addition, the inductors feature a three-pin design which ensures mechanical stability. A third pin which is unconnected at the back of the inductor distributes the weight and also balances the three terminals during mechanical vibration. The leads are flattened which serve as a pad making the coil self-leaded eliminating the need for an additional base.

Both the PG0871NL and PG0702NL series are RoHS compliant and meet standard EIA481 requirements. They are available in tape-and-reel packaging.
