Article content
KAWASAKI, Japan — Toshiba Electronic Devices & Storage Corporation ('Toshiba') has launched a line of 2-channel high-speed standard digital isolators for automotive applications. The new 'DCM32xx00 Series' features four devices that support stable operation with high common-mode transient immunity (CMTI) of 100kV/μs (typ.) [1] and high data transmission rate of 50Mbps (max) [2]. All conform to the AEC-Q100 standard for the safety and reliability of automotive electronic components. Shipments start today.
Article content
The safety and reliability of on-board chargers (OBC) and battery management systems (BMS) in hybrid-electric vehicles (HEV) and electric vehicles (EV) require devices that ensure isolation and prevent noise-propagation. Automotive standard digital isolators provide solutions for the multi-channel high-speed communications and high CMTI these isolation devices require.
Article content
The new isolators use Toshiba's proprietary magnetic coupling type isolated transmission method to achieve a high CMTI of 100kV/μs (typ.). This delivers high level resistance to electric noise between input and output in isolated signal transmission, enables stable control signal transmission and contributes to stable equipment operation. A low-pulse-width distortion of 0.8ns (typ.) [2] and a data-transmission rate of 50Mbps (max) [2] are also achieved. The new products are suitable for 2-channel high-speed communication applications such as I/O interfaces with CAN [3] communications.
Article content
Toshiba already mass produces 4-channel automotive standard digital isolators, and has now extended its product lineup to 2-channel small SOIC8-N packages. Going forward, the company will expand its range of channels and packages for automotive and industrial equipment. It will continue to provide high-quality isolation devices and photocouplers that support the reliability and real-time data transmission required by automotive equipment.

New Murata Automotive-Compliant Chip Ferrite Beads Deliver Wide Band Noise Suppression of High-Frequency (5.9GHz) C-V2X
Article content The new BLM15VM series is ideal for automotive powertrains and safety applications. It supports high frequencies. 1000Ω (Typ.) @5.9GHz. With its compact 0402-inch size (1.0×0.5mm) can operate at temperatures ranging from -55 to 150°C. And it is compliant with AEC-Q200. Article content KYOTO, Japan — Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) continues to push the envelope in automotive noise suppression technology with another industry first. By leveraging proprietary material technology and optimized structural design, the company's new BLM15VM series of automotive-compliant chip ferrite beads deliver wide-band noise suppression of high-frequency (5.9GHz) 5G vehicle-to-everything (5G-V2X) applications that exhibit high impedance. Mass production is scheduled to begin in July 2025. Article content Article content In recent years, the use of high-frequency wireless communication in the automotive sector has increased. It is primarily used for content distribution for navigation, audio and other infotainment systems. Improving sensitivity and noise suppression in these advanced high-frequency communication systems becomes mission critical to support the connected car for ADAS (Advanced Driver Assistance Systems) and eventually autonomous driving. Article content RF inductors typically used for noise suppression in sub-6GHz communication have a narrow frequency band at high impedance, making it necessary to select components that match the noise frequency band. With its broad high-frequency band at high impedance, the BLM15VM series allows easy noise suppression across multiple frequency bands using just one product. Even at 5.9GHz, the chip ferrite beads within the series will typically attain impedance values of 1000Ω. Article content By enabling error-free high-frequency communication, which is crucial for autonomous driving, the BLM15VM series significantly improves reception sensitivity in V2X communication in the 5.9GHz bands for autonomous driving and stable operation of dedicated short-range communication (DSRC) based control systems, operating in the 5.8GHz band, for improved road safety. Additionally, since Wi-Fi 6E and Wi-Fi 7, the communication standards for wireless LAN, also use the sub-6GHz band, this product can improve sensitivity and suppress noise in consumer communication devices. Article content The AEC-Q200-compliant BLM15VM series of chip ferrite beads from Murata supports operating temperatures between -55 to 150°C and is supplied in a compact 0402-inch size (1.0×0.5mm). Murata is committed to expanding its lineup to meet market needs. Article content Editor's Notes Article content According to the Company's research. This is the world's first product that removes noise in high-frequency communication (including Sub6 bands) for C-V2X, as of June 18, 2025. Article content About Murata Article content Murata Manufacturing Co., Ltd. is a worldwide leader in the design, manufacture and sale of ceramic-based passive electronic components & solutions, communication modules and power supply modules. Murata is committed to the development of advanced electronic materials and leading edge, multi-functional, high-density modules.
