TDK Corporation launches B58101A0851A000, the first in a new line of immersion temperature sensors (ITS), designed specifically for EV powertrain cooling applications. This highly responsive, fully sealed NTC thermistor is engineered to provide fast and precise temperature control, e.g., for oil-cooled systems. Oil cooling is anticipated to become the dominant temperature management method in the electric drivetrain of EVs. Leveraging TDK’s expertise in developing tailored temperature sensor solutions, the ITS offers a flexible, customizable design adaptable to various installation positions, cooling fluids, and mounting configurations.
Combined with a lightweight design (<11 g), the temperature sensor has a response time of less than 4 s (τ63%) and maintains an accuracy of below ±1 K over the temperature range of -40 °C to +150 °C. This can enhance the effectiveness of thermal management. The sensor is highly resistant to ZF EcoFluid E gear oil for electric drive systems, has a customizable resistance-temperature (RT) curve, and is available in various mounting configurations.
This immersion temperature sensor exemplifies TDK’s commitment to delivering precision-engineered, customizable thermal solutions for evolving e-mobility applications.
