Line Of SMT Power Inductors Targets High-Current Applications
Members of a line of surface-mount power inductors are mounted on a high-heat-resistant LCP material. The winding wire is wrapped directly to the platform to serve as the terminal point. This design ensures high reliability and low contact resistance in high-current applications.

According to the company, these inductors are suited for service as dc-dc converters, smoothing chokes, and EMI filters. The versatile SMT magnetic components can be used in a wide range of applications, including notebook computers, disc drives, automotive systems, digital TVs, VCRs, DVD players, and set-top boxes. Additionally, they may be used in battery chargers, handheld electronic devices, industrial electronics, and instrumentation.

Packaged in tape-and-reel form to accommodate high-speed automated assembly, the devices are constructed of high-temperature materials suitable for infrared reflow soldering. Available specifications include the PM3308 (10 to 1000 µH and 2.0 to 0.05 A), the PM3316 (1 to 1000 µH and 6.8 to 0.3 A), the PM3340 (10 to 1000 µH and 3.5 to 0.1 A), and the PM5022 (1 to 1000 µH and 8.6 to 0.56 A). Available now, pricing for the inductor line ranges from $0.90 to $1.62 for production quantities.

Tunable Inductor Is Well-Suited For HIgh-Q Filter Applications in the GHz Range
The 5Y is a 5-mm tunable thru-hole inductor. This device is specifically designed for high-Q filter applications in the GHz range. While an inductance range of 50 to 500 nH is offered, the Q specification is over 90.

A surface-mount side-tunable version of the 5Y will be available in production quantities soon. This device is slated to offer similar characteristics. In large quantities, the 5Y tunable inductor costs $0.20 to $0.30 each.

Surface-Mount Inductors' Protective Case Reduces Risk Of Core Breakage
The UNI-PAC UP B surface-mount inductors offer improved electrical characteristics and a protective case to reduce core breakage.This family of inductors are currently available in sizes 1 and 2. Sizes 3 and 4 will soon be available.

According to the company, the UP (1-4) B inductors offer a low-cost solution for high-power applications. The devices feature a miniature size and rugged construction. Possible applications include notebook computers, personal digital assistant (PDA) applications, and a variety of battery-powered equipment. Equipped with better roll-off characteristics, the UP (1-4) B family also offers lower DRC and a higher ISAT. They are suited for energy storage applications and high-shock environments.

The UNI-PAC inductors are available in tape-and-reel packaging, with 900 parts/reel. In 25,000-unit quantities, the UP 1 B version costs $0.40 each.
