Surface Mount Inductors

Gowanda Electronics has introduced a series of surface mount toroid inductors. The SMT35A series uses a core and package, and a 2-in-1 construction, that offers versatility and efficiency for power supply applications.

The series draws on the proven performance of the company's SMT45 series, but has been designed with a smaller footprint.

The SMT35A series is suitable for power supply applications where minimisation of power losses via smaller sized components is the goal. The 2-in-1 construction - a design with two windings on one core, offers versatility to design engineers who can use the SMT35A as a single inductor - with windings connected in series to deliver higher inductance or in parallel to deliver higher current - or use it as a 1:1 transformer.

The device uses a MolyPermalloy core, like the SMT45 series, to deliver stability over a wide temperature range and performance at higher frequencies.

These inductors are suitable for use in microprocessor and distributed power applications, including power supplies, power regulators and DC to DC converters, especially in test and measurement equipment, medical diagnostic equipment, and industrial process control equipment. Other applications include use in security systems, instrumentation, barcode and laboratory analysis equipment.

Specifications include: inductance from 0.22 to 300 µH and current ratings from 10.9 to 0.58 A for parallel connections; inductance from 0.88 to 1200 µH and current ratings from 5.47 to 0.29 A for series connections.

The SMT35A series is virtually self-shielding, is compatible with all reflow assembly processes, and is UL94 V-O flammability compliant. It has 300 V winding to winding isolation and is supplied on tape and reel for 'pick and place' processing.
