Built for full-switching power factor correction in 3-6 kW-power range motor drive applications, these devices include two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor, all in a 44 x 26.8 mm package, using half the board space of other modules. They offer 99 percent power factor for the mandatory PFC standard, plus 40 kHz switching operation. They offer under-voltage and over-current protection with a built-in gate-driving IC. They have an isolation voltage rating of 2500 Vrms/min. They use the company's own Direct Bonded Copper-based transfer-molded packaging technology for better thermal efficiency.

The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
