MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has announced the launch of its new AEC-Q200 qualified NTC immersion thermistor, designed to meet the stringent demands of liquid-cooled automotive systems. The Vishay BCcomponents NTCAIMM66H offers rapid response, durability, and flexibility for applications in electric and hybrid electric vehicles (EV/HEV).
Engineered with a compact sensor tip and thin insulated wiring, the NTCAIMM66H achieves a fast thermal response time of just 1.5 seconds. This makes it especially suited for precise temperature monitoring and control in tight spaces, such as onboard chargers, charging plugs and sockets, and other critical thermal management components in modern electric vehicles.
The device integrates a miniature NTC thermistor encased in a corrosion-resistant stainless steel 316L housing with lead-free brass components. Its robust AWG#22 insulated lead wires, featuring FLR2X construction, support traction forces over 30 N and allow for direct crimping to automotive connectors. This eliminates the need for additional wire-to-wire connectors, reducing system complexity and cost.
Beyond automotive applications, the NTCAIMM66H is well-suited for solar heating systems, energy storage solutions, industrial tools and drives, and data servers. Customization options, including varied cable lengths, gauges, and conductor plating, enable seamless integration into specialized sensor assemblies.
Key performance features include a resistance of 10 kΩ at 25 °C with ±2% tolerance, a beta value of 3984 K with ±0.5% tolerance, a maximum power dissipation of 100 mW, and an operating temperature range from -40 °C to +125 °C.
With the growing focus on efficient thermal management in EVs and other advanced systems, Vishay’s latest thermistor positions the company to support customers seeking reliable, high-performance temperature sensing solutions for demanding environments.
