Two new MAF1608GAD-L noise-suppression filters, designed for audio lines, have a footprint of 1.6 x 0.8 mm and an insertion height of 0.6 mm. They offer rated currents of 3.2 and 2.3 A, respectively, and low DC resistances of typically just 0.021 and 0.045 Ω. Their impedance at 900 MHz is 120 and 200 Ω, respectively. Their low DC resistance and rated current of more than 2 A make them suitable for smart speakers and external speakers for tablets that require power levels of 2 W or higher as well as for headphones and microphones.

A new common-drain dual n-channel 60-V MOSFET in the compact, thermally enhanced PowerPAK 1212-8SCD package can increase power density and efficiency in battery-management systems, plug-in and wireless chargers, DC/DC converters, and power supplies. The SiSF20DN offers RS-S(ON) down to 10 mΩ typical at 10 V in a 3-mm by 3-mm footprint. The vendor reports this value is 89% lower than for its previous-generation devices. The result is reduced voltage drop across the power path and minimized power loss. The device uses an optimized package construction with two monolithically integrated TrenchFET Gen IV n-channel MOSFETs in a common-drain configuration.

The DAS30/50/60 data recorders feature a sampling interval of 1 µs (1 MS/s), an input range of ±5 mV to ±500 V, and internal solid-state memory to 64 GB. With a CAT III isolation rating, these instruments are suited for a range of applications from sensor signal logging to electrical power analysis. A built-in power-analysis application measures and records voltage and current on both single and 3-phase networks. The results are displayed as a harmonics graph, Fresnal diagram, and oscilloscope waveform. An integrated thermal printer is optional for all three models.

A new SoundCheck test sequence predicts listener headphone preference based on statistical models developed by Sean Olive, Todd Welti, and Omid Khonsaripour of Harman International. The sequence measures a headphone in SoundCheck and saves the results to an Excel template. Within Excel, a predicted preference score on a scale of 0 to 100 is calculated based on the Harman Target Response Curve. The calculation involves subtracting the target curve from an average of the headphone left/right response to obtain an error curve and analyzing this curve to calculate the score.
