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 ...

Taiwan Semiconductor has introduced ten AEC-Q101-qualified small-signal mosfets. There are seven n-channel parts (including two duals), and three p-channel parts (one dual) in the ‘TQM’ line – see the table below. Three packages are used: SOT-236, SOT-363 or SOT-323, and they are rated for >2kV ESD withstanding. “In addition to automotive applications, these small-footprint MOSFETs are ideal for high-reliability commercial designs ...

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 ...

Stackpole is offering 0.01% 2ppm/°C precision surface-mount resistors in sizes from 0402 to 2512 (1 x 0.5mm to 6.3 x 3.1mm). Part of its RNCF range, these highest spec parts don’t come in the wide value range of lesser RNCF resistors. For example: 0402 types are available between 49.9Ω and 4.99kΩ, then 2512 has the widest span of options,  between ...

Murata has created a 1210 (3.2 x 2.5 x 2.5mm) wide-band wire-wound chip common mode choke that will attenuate noise on 1.2A automotive supply rails at over 1GHz. “It is of particular value when addressing the power supply line noise issues now occurring as driver assistance hardware connects with wide frequency band sensors and imaging equipment such as radar and ...

ROHM has created a range of five different coloured 0603 (1608 metric 1.6 x 0.8mm) LEDs, the CSL1901 series, optimised for 2mA operation. “In recent years, technological advancements have resulted in dramatically improved luminous efficiency”, according to the company. “At the same time, the market is demanding LEDs tailored to characteristics in the low current range.” It argues that LED ...

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 ...

Stackpole Electronics is aiming at consumer and industrial electronic devices with a surface-mount 3.5W current-sensing resistor. Called CSRT2512-UP, it comes in a 2512 case size – 6.3 x 3.2 x 0.7mm. “The AEC-Q200 compliant CSRT2512-UP has unique thin film material properties and processing to provide higher continuous power ratings and higher pulse power ratings than other thin film chip resistors,” according to ...
