Passives

  Melexis has introduced the MLX92223, a PCB-less 2-Wire Hall-Effect Latch with integrated passives (392Ω resistor and decoupling capacitor), making it compatible with industry-standard Electronic Control Units (ECUs) without the need for any additional external components.

A series of high voltage thick film chip resistors that offer high power ratings up to 1.5 W and working voltages to 3000 V in five compact case sizes ranging from 1206 to 2512 has been introduced by Vishay Intertechnology. For increased design flexibility, the Vishay Techno CRHP series is available in a variety of styles, termination materials, configurations, and custom sizes.

At the embedded world Conference 2019, imec presented a silicon-based compact microchannel heat sink that enables high heat flux dissipation. The imec heat sink assembled to a high performance chip for cooling the latter one achieves a low total thermal resistance of 0,34K/W to 0.28K/W at less than two watt pump power.

Manufacturer of electronic components, AVX Corporation, has released the new λ-Bridge (Lambda-Bridge) Series thermal conductors. Constructed with high-quality aluminium nitride (AlN) or beryllium oxide (BeO) materials, Lambda-Bridge thermal conductors provide efficient, cost-effective thermal management solutions with reliable, repeatable performance in four small EIA form factors: 0302, 0402, 0603, and 0805.

If you are designing products like a home appliance, security panel, a door-entry system or a computer peripheral, you might choose to feature a buzzer as the sole means of interacting with users or as part of a more sophisticated user interface.

The popular RAVF series convex termination chip resistor arrays and RACF concave termination arrays from Stackpole are available as the company currently have many of the most popular sizes, styles, and resistance values in stock. The RAVF and RACF are AEC-Q200 compliant for popular sizes.

The WSBS5216 and WSBS5216...14 12 W Power Metal Strip battery shunt resistors from Vishay Technology come in the compact 5216 case size. With extremely low resistance of 100µΩ, the Vishay Dale AEC-Q200 qualified devices increase accuracy and lower costs compared with Hall Effect current sensing solutions, while the optional Sn terminal plating of the WSBS5216...14 assists with PCB mounting and provides improved corrosion protection.

It has been announced that Stackpole's ZV Series of multilayer varistors protect low voltage electronics from high voltage transient surges. The ZV is available in sizes 0603, 0805, 1,206, 1,210, 1,812, and 2,220 in AC operating voltages from two to 130V, DC operating voltages from three to 170V.

Availability and full design support capabilities for a new ultracapacitor cell from Maxwell Technologies have been announced by Richardson RFPD. The Maxwell 3-volt (3V), 3400-farad (3400F) cell has been designed to be the highest energy, highest power workhorse of its ultracapacitor portfolio.

The T55 series of vPolyTan surface-mount polymer tantalum moulded chip capacitors from Vishay Intertechnology has been extended with devices in the Z case (EIA 7343-19) size. With a 0.1mm lower height than devices in the standard V case (EIA 7343-20), the Vishay Polytech capacitors increase package density and enable the design of thinner end products.
