Automotive Thermistor

Thermistors for Automotive Temperature Sensors

In the automotive industry, precise temperature management is essential across a wide range of applications, including engines, motors, batteries, and inverters, directly impacting vehicle performance, safety, and electrification.

Shibaura Electronics’ thermistor sensors offer high sensitivity and excellent heat resistance, enabling stable and reliable temperature detection even under harsh automotive operating conditions.

Our solutions support not only engine-related applications in ICE (Internal Combustion Engine) vehicles, but also intake and exhaust system sensing, battery temperature monitoring for EVs and HEVs, and electric powertrain control systems. We can provide optimized sensor designs and custom sensor processing tailored to specific operating environments and installation requirements.

In addition, we offer flexible support for mass-production programs, ensuring stable supply and accommodating customer-specific requirements.

Shibaura Electronics’ thermistor sensors offer the following features ideally suited for automotive applications:

  • High sensitivity, excellent heat resistance, and outstanding long-term stability enable reliable temperature sensing even in demanding environments around engines, motors, batteries, and inverters.
  • Fast-response thermistor elements allow rapid detection of temperature changes in engine coolant, oil, solid surfaces, and ambient air.
  • Compatible with a wide range of temperature ranges and measurement targets in EVs, HEVs, and ICE (Internal Combustion Engine) vehicles, with customizable sensor configurations including sensor housing design, lead wires, terminals, and connectors according to installation locations and protection requirements.
