C&K has added a cold white illuminated and waterproof key switch to its K12S range. Called K12S Bright White, the “cold white illumination option addresses the growing need for a high-quality switch with brighter illumination for high-volume industrial and automotive manufacturing”, according to the company. The switches are surface-mount and cylindrical: close to 11mm in diameter and 9mm tall above ...

Analog Devices has had its wirelessly-linked electric vehicle battery management systems certified to the new ISO/SAE 21434 standard for whole-life cyber-security risk management. It is “the highest standard of automotive cybersecurity engineering and management”, according to ADI, managing security “from concept, product development and production, to operation, maintenance, and decommissioning of electrical and electronic systems.” The company’s wireless battery manager ...

P-Duke is aiming at rail and industrial use with a family of 20W 25.4 x 25.4mm dc-dc converters with wide input ranges. Depending on part, they take 9 to 75Vdc, or 14 to 160Vdc, and turn that into single or dual outputs of 5, 5.1, 12, 24, ±12 or ±15Vdc. “Using just one dc-dc model converter for 24, 28, 36, 48, 72, ...

Vishay has announced 0805 SMD resistors that combine 450V operation with ±0.1% tolerance and a temperature coefficient as low as ±10ppm/K. They are the TNPV0805 e3 series, introduced as part of the greater TNPV e3 series (table below) of automotive high-voltage thin-film flat chip resistors. “Typical applications for the AEC-Q200 qualified device will include voltage measurement in automotive and industrial inverters, voltage dividers ...

ITG Electronics has introduced a line of high current flat wire inductors for automotive and industrial environments. Called the L201316Q series, it offers nine inductance choices from 1.00μH to 105μH, and emphasises high current capability with examples of 75A for the 11.6μH part and 25A for the 105μH inductor. These are both 30% inductance drop figures at 25°C. The 20% drop ...

Need to deliver power and data 300m away, and you only have a coaxial cable to do it? Advantech might have just the thing for you, with its IMC-150LPC PoE (power-over-Ethernet) extender. “This device uses extant coaxial cables and and makes the IMC-150LPC an excellent choice for industrial and rail network infrastructure upgrade projects with limited power and network resources,” according ...

Nexperia has released electro-thermal models for some of its mosfets, many of them automotive qualified. It “developed these models in close partnership with a Tier 1 OEM whose requirements could not be satisfied by any others currently available”, according to the company. “Simulation models for mosfets usually include a limited number of device parameters modelled at typical operating temperatures. Nexperia’s ...

To support the growth in the EV charging infrastructure, needed to encourage EV adoption, Farnell has announced that it is shipping fast charging components from Murata, from stock. The company has added common mode choke coils, dc-dc converters and capacitors used in EV charging systems. The DLW series common mode choke coils (CMCC for signal and power are designed to reduce the ...

NXP and Hitachi have co-designed a gate driver evaluation board for Hitachi’s 1.2kV RoadPak SiC mosfet half-bridges. The half-bridges are ~75 x 70mm and come in 580, 780 and 980A versions which are liquid-cooled – one side having a pin-fin array (just visible right) which has to be sealed into a water-glycol filled cooling manifold. Junction to fluid resistance is typically ...

A low-noise dc-dc converter and a low-noise LDO are debuting on TI’s APEC stand, alongside an 11kW 800V GaN three phase inverter design. LMQ66430 is a 36V 3A buck converter that includes two input bypass capacitors and one boot capacitor and includes the company’s ‘dual random spread-spectrum’ jittering technique, “enabling engineers to easily meet CISPR 25 Class 5 EMI standards while offering 1.5µA ...
