Vishay BCcomponents has extended its broad portfolio of SMD devices with new values for the NTCSโฆ.E3โฆ.T series of glass-protected NTC thermistors.
Parts offering the new values include 1 kโฆ and 1.5 kโฆ devices in the tinned nickel 0603 and 0805 cases (NTCSโฆ.102.LT and NTCSโฆ.152.LT). Such low resistance values at 25 ยฐC allow for higher currents when the components are powered, for example, in devices like of 4 mA to 20 mA converters.
A new popular value of 5 kโฆ has also been introduced in the 0603 and 0805 ranges, providing compatibility with Shibaura MELFs used in IGBT and power MOS modules. This eliminates the need to modify firmware when using our standard 4.7 kโฆ in place of a 5 kโฆ device. These new values are supplied with a ยฑ 1 % tolerance on the B25/85 value (slope of resistance in temperature).
The devices have been qualified under AEC-Q200 testing procedures and can be used at temperatures as high as 150 ยฐC. The components are also provided with a specific plug and play SPICE model for easy application integration. Their resistance temperature curves are available online.
Key Advantages
- Extension of the range limits
- Higher current compatible with mitigated self-heating
- Compatible with competition
- Stability up to 150 ยฐC
- AEC-Q200 qualification
