Miniature AEC-Q200-certified power inductors have a low profile
TT Electronics, a global provider of engineered electronics for performance critical applications, has announced the introduction of the HA66 SMD power inductors for use in high power density applications where size is critical. The inductors’ compact design, together with their AEC-Q200 certification provide the performance and reliability levels that automotive and high reliability industrial applications demand. […]
High-reliability thick-film resistors come in 0603-sized packages
TT Electronics has announced the introduction of two additional resistor types that expand and enhance its high-reliability CR and HR series. The latest versions of these thick-film chip resistors are in the smaller 0603 size and hence offer greater opportunities for use in compact circuits where guaranteed performance and footprint size are critical. For use […]
Current sense resistors for power supply and motor drive designs feature values down to 200μΩ
The LRMAP5930 series of low resistance, metal alloy current sense power resistors feature values down to 200μΩ and a corresponding power rating on standard FR4 PCB of up to 10W, the maximum measurable current is over 200A, and hence in most cases restricted only by the capacity of the PCB tracks. A 50% higher power […]
High pulse-withstanding resistors in a compact package
The HPWC (high pulse withstanding chip) range of high energy surge resistor products are designed to maximise the level of surge performance available in a single-sided flat chip design. The HPWC range targets protection and discharge applications in compact power supplies and power control circuits that need a resistance tolerance of five percent. Available in […]

Getting started in electronics: core components
By “Spec“, Electro-Tech-Online forum member Often newbies ask, ‘How can I get started in electronics?‘ This is a big question, but the very short answer is, ‘Learn the two fundamental electronics laws (Kirchoff, Ohm), get a good book about electronics theory and practical, build some circuits, and make some measurements.’ Follow-on questions are, ‘What electronic […]
