New Product Announcement May 2014 KR Series: NTC Surface-Mount Thermistors The News: Ametherm introduces a new series of NTC surface-mount thermistors for highaccuracy temperature measurement. Key Benefits: Wide range of resistance values Fast thermal response times Tight tolerances Available in standard EIA 0805, 1005, and 1206 case sizes Provide an alternative to radial leaded devices High-temperature operation to +150 °C RoHS-compliant and lead (Pb)-free Five-sided wraparound, silver palladium terminations Available in bulk or tape-and-reel packaging Target Applications: Temperature measurement, compensation, and control in LCD controls and power transistor stabilization Key Specifications: Resistance at 25 °C: 100 Ω to 150 kΩ Tolerances: ±5 % and ±10 % Negative temperature coefficients at 25 °C: -3.3 %/°C to -4.7 %/°C Dissipation constant: 2 mW/°C Maximum power ratings at 25 °C: 250 mW The Context: Recently acquired from RTI Electronics, Inc., Ametherm's KR series of NTC surface-mount thermistors offers designers a wide range of resistance values at 25 °C and three standard EIA case sizes to choose from. The devices feature fast thermal response times, tight tolerances, and negative temperature coefficients between -3.3 %/°C and -4.7 %/°C at 25 °C. Providing an alternative to radial leaded devices, the NTC surface-mount thermistors deliver high stability, reliability, and sensitivity for temperature measurement, compensation, and control in a wide range of applications. Availability: Offered through Sager Electronics, Mouser, and Dexter Magnetic Technologies, samples and production quantities of the KR series are available now, with factory lead times of six weeks.
