Automotive-qualified fuses save space on crowded boards
With interrupting current ratings up to 1,500A, a new series of surface-mount fuses has been introduced by Littlefuse. The series is optimised for use in high voltage automotive applications up to 350VAC or 450/500VDC. NANO2 885 Series Fuse is designed to protect electric vehicles against severe fault/short-circuit currents, ensuring reliability in harsh environments.
Low power PIR motion detector design: Analogue vs. digital solutions
This video covers the fundamentals of PIR motion detector design, and analyses the differences between analogue and digital solutions.
300W chassis mounting DC-DC converters
Powersolve has made available the TZL Series of high performance DC-DC converters. With a wide 2:1 input range and capable of providing between 60 and 300W from a compact chassis-mounting metal cased unit, TZL units are designed for those applications requiring a very reliable power source with a long MTBF.
Automotive power MOSFETs housed in low resistance package
Toshiba Electronics has released two new MOSFETs housed in the small low resistance SOP Advance (WF) package in 5x6mm size, as new additions to the automotive 40V N-channel power MOSFET series. The TPHR7904PB and TPH1R104PB are AEC-Q101 qualified and are intended for a variety of automotive applications including Electric Power Steering (EPS), load switches, electric pumps, fans and more.
Two eGaN discrete transistors are qualified to AEC Q101 for automotive use
Two eGaN discrete transistors are qualified to AEC Q101 for automotive applications, announces Efficient Power Conversion (EPC). The company believes the certification brings its eGaN technology to vehicle design.
A guide to power factor correction
BEAMA has announced that it has published its 'Guide to Power Factor Correction'. This paper has been written with the member of BEAMA's Capacitor's Group, experts in the field of power factor correction.
Step-down regulator operates in noisy environments
Able to operate in factory automation, industrial robotics, communication infrastructure and avionics systems, the LTM4653 is a 58Vin step-down µModule regulator from Analog Devices.
Inductor delivers up to 250A continuous current rating
A Very High-Current Through-Hole Inductor - the Vishay Dale IHXL-2000VZ-5A – is available from New Yorker Electronics. The Vishay IHXL technology combines the metal composite construction of a pressed metal powder with an insulating binder which allows for high saturation magnetisation and high field strength – so it handles high transient current spikes without saturation.
Gate drivers enhance robustness in harsh environments
Power Integrations has introduced factory conformal coating for its SCALE IGBT and MOSFET drivers. Conformal coating enhances system reliability by protecting electronic components against contaminants such as pollution, dust and condensation, which may cause corrosion. Power Integrations’ factory-coated gate drivers reduce inventory cost, lead time and overall cost of ownership by eliminating the need for manufacturers to se...
