Superior SMD PTC Thermistors

EPCOS Superior SMD PTC thermistors for limit temperature measurement are available in case sizes 0805, 0603, and 0402. Compared to the standard series, EPCOS Superior thermistors employ a more homogeneous ceramic material that enables them to exhibit excellent performance in reliability tests and be reflow and wave-soldered at temperatures of up to +280°C. These EPCOS SMD PTC thermistors are qualified based on AEC-Q200 Rev-C and satisfy the rigorous requirements for use in automotive applications involving frequent and rapid temperature changes. The B59721A in case size 0805 has response temperatures from +70° to +130°C in steps of 10K and a 680Ω rated resistance. The response temperatures of the B59641A (0603) and B59421A (0402) are from +75° to +145°C and +75° to +135°C respectively, also in steps of 10K and feature a rated resistance of 470Ω.
