Vishay Intertechnology RCWK0306 thick film chip resistors save space

Claiming to deliver increased accuracy while saving space and reducing component counts, the Vishay Dale RCWK0306 series resistors are available from Vishay Intertechnology.

The thick film surface-mount chip resistors feature four-terminal Kelvin connections and high power ratings of 0.33W in the compact 0306 case size. Offering a power density over 3.3x higher than standard devices in the 0603 footprint, the RCWK0306 series resistors are designed to save space and reduce component counts in telecommunications, computer, industrial, and consumer applications, says Vishay.

The high power density enables the resistors to be used instead of larger high power components or multiple lower power devices. This reduces board space requirements and placement costs while enabling smaller and lighter end products, points out Vishay. In addition, adds the company, the RCWK0306 series resistors provide higher reliability than larger thick film devices by reducing the co-efficient of thermal expansion (CTE) mismatch with the printed circuit board (PCB), thereby lowering solder joint stress.

The RCWK0306 series resistors’ four-terminal Kelvin connection enables greater measurement accuracy with extremely low resistance values from 0.01 to 0.1-Ohm and tolerance of one per cent.

RoHS-compliant and halogen-free, the RCWK0306 series resistors feature a metal glaze thick film on high quality ceramic. They are optimised as current sensing resistors in DC/DC converters, voltage regulation modules, and inverters in cell phones, computers, air conditioners, and heat pumps.

Samples and production quantities of the RCWK0306 are available now, with lead times of six to eight weeks for large orders.

Vishay Intertechnology,is one of the world’s largest manufacturers of discrete semiconductors (diodes, metal oxide semiconductor field-effect transistors (MOSFETs), and infra red (IR) optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in electronic devices and equipment in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
