Vishay / BC Components NTCC201E4 Enhanced Leadless NTC Thermistor Dies provide versatile mounting options with contacts on the top and bottom. These modules 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. The AEC-Q200-qualified devices operate over a wide temperature range of -55°C to +175°C and 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 the Vishay NTCC201E4 thermistor dies feature 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 of up to +360°C. An internal layer resists board formic acid etching when solder preforms are used and forming H2/N2 gasses.
