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.
