In addition to those specifically created for usage over 150 °C, there are special families of leadless NTC thermistor dies that can be utilized at temperatures close to absolute zero (-273.15 °C).
“Percentage change per degree C” or “Percent change per degree K” are two ways that NTC sensors communicate their temperature sensitivity.
An NTC thermistor can attain the best accuracy among the fundamental sensor types between -50°C and 150°C, and up to 250°C for glass-encapsulated thermistors. The range of accuracy is 0.05°C to 1.00°C.
The Global Leadless NTC Thermistor Dies market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Two leadless NTC thermistor dies with contacts on the top and bottom have been made available by Vishay, giving designers the same mounting possibilities as IGBT semiconductors.
The NTCC200E4 with silver metallisation supports aluminium wire bonding and is compatible with reflow soldering and nano-silver paste sintering, whereas the NTCC300E4 with gold metallisation supports gold wire bonding and conductive adhesive gluing.
In automotive and industrial applications, the devices are optimized for temperature detection, control, and adjustment. IGBT modules, power inverters, motor drives, hybrid ICs for EVs and HEVs, solar cells, and wind turbines will all be among the finished items.
The NTCC300E4 and NTCC200E4 are conductive PS blister tapes that are resistant to leaching and have high stability across a temperature range of -55 to +175°C with a drift of under 3% after 1,000 hours.
According to AEC-Q200 automotive requirements, the devices have a drift of less than 3% after 1,000 cycles and are very robust to thermal shocks.
The RoHS-compliant thermistors provide beta (B25/85) from 3435 to 3865K with a tolerance of 1% and resistance at +25°C (R25) from 4.7 to 20k with a tolerance of 1%. The devices have response times of 5s and a maximum power dissipation of 50mW.
