Leadless NTC Thermistor Dies’ New Series

Samples and production quantities of the NTC thermistor dies are available now, with a lead time of 20 weeks.

A new series of leadless NTC thermistor dies has been introduced by Vishay Intertechnology. NTC thermistor dies with silver metallization support aluminum wire bonding and are compatible with reflow soldering under vacuum or with formic acid / forming gasses, SAC or SMP soldering, and nano-silver paste sintering.

Leadless-NTC-Thermistor-DiesOperating over a wide temperature range from -55 °C to +175 °C, the AEC-Q200 qualified NTC thermistor dies released recently are optimized for temperature sensing, control, and compensation in automotive and alternative energy applications. End products will include IGBT and power MOSFET modules and power inverters for electric (EV) and hybrid electric vehicles (HEV), solar panels, and wind turbines.

The top and bottom metallization of NTCC201E4 features two layers. An external layer offers superior resistance to soldering leaching compared to previous-generation devices, especially when using high melting point solder materials at temperatures to +360 °C. An internal layer resists board formic acid etching when solder preforms are used and forming H2 / N2 gasses.

RoHS-compliant, halogen-free, and Vishay Green, the thermistor offer resistance at +25 °C (R25) from 4.7 kΩ to 20 kΩ, with tolerance down to ± 1 %, and beta (B25/85) from 3435 K to 3865 K, with tolerance down to ± 1 %. The NTC thermistor dies feature maximum power dissipation of 50 mW, response times of 3 s, and are packaged in PS blister tape.

Samples and production quantities of the NTCC201E4 series are available now, with a lead time of 20 weeks.
