More recently, physics-based reliability prediction has related failure rates of electronic assemblies to the magnitude of temperature change over an operational cycle (power-on, power-off, power-on…) and rate of temperature change, both of which are influenced by steady-state operating temperature. Electronics failures are often attributed to solder joint fatigue at the package-board interconnect. In some applications, […]
Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates are driven from a charge pump to a voltage above the […]
April 10, 2024 — TDK Corporation recently introduced the B40910 series of hybrid polymer capacitors which can handle up to 4.6 A (100 kHz, +125 °C). This is because at room temperature the surface mount components offer an extremely low ESR value of 17 mΩ and 22 mΩ, respectively. Furthermore, their ESR does not change as much with temperature as […]
Radial flux AC motors offer some performance and packaging benefits but also bring some thermal and manufacturability issues. For many electrical and even mechanical engineers, motor selection is somewhat mysterious. You can understand their basic principles and operation. Still, the real-world design considerations of their flux paths, poles, materials, and tradeoffs seem to be defined […]
April 1, 2024 — According to the supply chain, as the power of AI servers increases, the consumption of passive components such as inductors increases by 2 to 3 times, and passive component manufacturers are expected to benefit from this. Industry insiders said that Nvidia’s AI servers will drive a surge in demand for inductors, […]
Nisshinbo Micro Devices has launched the NR1620 series voltage regulator with dual input pins to supply low-power microcontroller cores and other applications. The NR1620 has an output current of 150mA, allowing it to handle a wide range of applications and its quiescent current of 0.4 µA makes it suitable for systems that demand low power […]
Key Things to Kow: Mass Production Evolution: The transition from through-hole to surface mount technology has significantly reduced the size and cost of electronics, enabling mass production and global distribution. Environmental and Ethical Concerns: The electronics industry faces challenges related to e-waste, environmental damage from raw material extraction, and ethical issues in manufacturing locations. Localised […]
Called the ZL series, the parts come in five case sizes from 5mm diameter (ø) x 5.8mm high (47 or 82μF), to 10ø x10.2mm (470 or 680μF). There are two capacitance values at each case size, one rated at 25V and a smaller capacitance rated at 35V. The company makes two other comparisons with its […]
Differential-mode and common-mode currents can cause your product to produce radiated and conducted emissions. These three techniques can help you measure them. If you’ve dealt with EMC issues for any length of time, you’ve probably run into the term “common mode currents,” which often lead to radiated emissions. Common mode (CM) and differential mode (DM) […]
