!Note
PRF18_RB1RB series is an improvement on sensing
accuracy from existing PRF18_QB1RB series.
1. Sensing accuracy +/-3 deg.C which is highest of
2. Same resistance-temperature characteristics as
3. SMD type is helpful for miniaturizing circuits
4. Excellent thermal response due to small size
5. Solid-state construction provides excellent
6. Contactless operation provides noiseless operation.
7. Lead is not contained in the terminations.
