Bourns has created a surface-mount thin-film resistor series with AEC-Q200 compliance for automotive use. Model CRT-A resistors are available with tolerance of ±0.1, ±0.25, ±0.5 or ±1%, and temperature coefficients of ±50, ±25, ±15 or ±10ppm/°C. These compact, yet high power-rated resistors offering accurate resistance levels are increasingly required in space-constrained applications such as mobile phones, SD cards, DDR memory ...

Infineon is putting 650V silicon carbide mosfet die into two packages with SO-type footprints: a thin (1.5mm) bottom-cooled 8 x 8mm leadless TO (TOLL – TO leadless), and 9.8 x 15 x 2.3mm 16 leg SO version with top-side cooling (‘TOLT’ package) (see photo). Die with typical on-resistances of 20, 40, 50 or 60mΩ are available in either package, and ...

Nexperia has put 1,200V silicon carbide mosfet die into D2PAK-7 surface mount package, also known as TO-263-7. “SiC switches in SMD packages like D2PAK-7 [are] becoming increasingly popular in industrial applications including electric vehicle charging, uninterruptible power supplies and inverters for solar and energy storage.” NSF0xx120D7A0 is the SiC mosfet family name, and they come with different on-resistances: NSF030120D7A0 30mΩ ...

Component distributor Rutronik is offering a series of tiny surface-mount magnetically shielded power inductor from Knitter, The ICSIxxxxxxTxSHyST12 series spans sizes between 1.6 x 0.8 x 0.8mm and 6.6 x 6.4 x 3.1mm, inductance from 0.1 to 10μH and saturation currents from 1.3 to 35A. “The inductor series works reliably at operating temperatures from -40 to +125°C and is suitable ...

Delvitech is proud to announce and show a new generation of Automated Optical Inspection systems for the electronic and mechanical manufacturing. Electronic assembly process is moving towards more and more hidden complexity. Varied shaped parts increasing difficulties related to shadows, large components with small pins, high components with short pins, continuous changeover in production due to parts availability, mix of ...

With the Raspberry Pi Pico in mind, UK company OpenLX SP has answered the question: ‘how do I temporarily mount a castellated solder-down PCB module?’. The answer is a connector dubbed Clipzin, which is used in pairs to create a socket for the un-modified castellated module. However, although the connectors are surface mount, they will not mount directly onto the ...

Stackpole has extended its CSRF2817 range of surface-mount foil-on-ceramic resistors up to 100mΩ – it continues to reach down to 3mΩ. “For devices that need somewhat higher resistance values, high current handling, low temperature coefficient and high stability, finding cost effective solutions can be challenging,” according to the company. “Film type resistors will not have high current handling, and all ...

C&K has added gold-plated contact versions to three of its miniature slide switch families for enhanced environmental protection, and enhanced switching for low-energy circuits. “Whether end-products are exposed to damp air or sulphide-containing environments, gold plating decreases the potential risk of electrical short circuits due to the age of plating with dendrite growth caused by silver migration. In addition, the ...

Schurter has introduced a through-hole fuse holder specifically designed to be compatible with reflow soldering. It is branding this as ‘THR’ for ‘through-hole reflow’. “Highly integrated electronic circuits are almost exclusively assembled with surfact-mount components and soldered in a reflow oven, however, it is sometimes necessary to include through-hole components on the circuit board,” according to the company. “THR components ...

Nexperia has released 20V and 30V mosfets in DFN0603-3 (SOT8013), “the smallest DFN package”, it said. The company already offers ESD protection devices in the 0.63 x 0.33 x 0.25mm package. “Next generation wearable and hearable devices are creating several challenges for product designers,” it said. “Firstly, available board space is at a premium as functionality is added, plus heat ...
