ROHM Semiconductor has recently announced the development of low-ohmic chip resistors optimized for current detection applications in compact equipment such as smartphones and wearable devices. The UCR006 series of ultra-compact (0.6mmx0.3mm) thick-film chip resistors is offered in resistances as low as 100mOhm, providing greater energy savings. They are also the first 0603-size resistors in the industry to ensure a temperature range of -55 to 155°C in the low-ohmic region, and feature twice the rated power compared with competitor products in the same size, enabling support for a wide range of applications. This higher power handling capability in a smaller size makes them ideal replacements for larger 1005-size (1.0mm x 0.5mm) resistors, contributing to further miniaturization.
In order to operate smartphones and other electronic devices it is necessary to control the voltage and detect current internally, and resistances exceeding 100mOhm are typically used. But to minimize power loss during current detection it is important to use the smallest resistance value possible - while also providing sufficient power rating to ensure reliable performance.

In recent years Silicon Carbide (SiC) has emerged as one of the most viable candidates in the search for a next-generation, low-loss power semiconductor element due to its low ON resistance and superior high temperature, high frequency.
ROHM has released a new sensor shield (expansion board) equipped with 8 sensor boards (e.g. accelerometer, barometric pressure, geomagnetic, heart rate sensors, etc.) designed for use with existing open platform MCUboards such as Arduino, and mbed.
ROHM has launched a 12 to 76V input, 3A variable output voltage, DC/DC Buck converter with integrated 76V MOSFET optimized for high power (high voltage x large current) applications such as motors, factory automation equipment, communications
