J.W. Miller's New Multi Six Pack Doubles as SMT Inductor or Transformer and Provides Multiple Configuration Connections


GARDENA, Calif. - April 21, 2003 - J.W. Miller, a leading provider of custom and standard magnetic components, has introduced the Multi Six Pack surface mount Inductor/Transformer Series. The new device features dual functionality by acting as either an Inductor or a Transformer with three sizes providing a multitude of connection options for optimum connection versatility.

The device's six-winding design allows engineers to wire each coil differently to create a wide range of values for individual application requirements. Functions can be changed without the need to add additional components to the board, saving space and providing more versatility for designing and modifying the board.

This new series is offered in three sizes with the smallest measuring just 12.2 x 12.7 x 6.2 mm (W X D x H), and is available in 32 part numbers. The six winding design allows over 20 different connection combinations per part number, providing over 600 inductor or transformer configurations.

As an inductor, the series is ideally suited for a wide range of applications including buck, boost, coupled, input, output, choke, filter, resonant, high-Q, EMI/RFI filtering, differential, forward, and common mode chokes. When used as a transformer, typical applications include fly back, forward, push-pull, bridge, multiple outputs, inverter, step-up, step-down, gate drive, base drive, signal, wide band, pulse, impedance, isolation and converter.

The device's six strand wound coils provide excellent magnetic coupling to create a high efficiency signal integrity. Performance characteristics include a frequency range to over 1 MHz, operating temperature range of -40 to +105°C, and dielectric strength of 500 Vrms between each winding. Other special features include low profile, low core loss at high frequency applications and low noise radiation.

This new series is available in non-gapped core construction and gapped core styles. The non-gapped core construction style is ideally suited for high inductance, low DCR and high Q, while the gapped core style is designed for high DC current and applications requiring better temperature stability.

Multi Six Pack surface mount devices are shipped in tape and reel or tray packages priced from $0.95 in production quantities.

J.W. Miller offers a full line of high-quality surface-mount and through-hole coils, chokes, inductors and transformers for short run or high volume production requirements and maintains a large inventory of standard components for quick delivery.
