POSITIVE THERMISTORS "Posi-R" For Thermal Protection 18 0.8 4.5MAX. 4.2 5.0 1.5 IG IE IA IC OT OR Resistance () 8.1 6.0MAX. OX 10k This series of Posi-R as a temperature indicator is small in size and little in calorific capacity. It is so useful for indicating any overheating of power transistors and thyristors in the power sources. 1k 500 100 0.6 5.0 1.5 0.6 ZPP35 Type 30 10 ZPP22 Type 50 100 150 Temperature (C) Fig. 12 Resistance vs.Temperature Characteristics Type No. Temperature Indication 25C Tr(C) ZPP35 Type ZPP22 Type ZPP350R500E ZPP220R501E 70 ZPP350T500E ZPP220T501E 80 ZPP350X500E ZPP220X501E ZPP351A500E ZPP221A501E ZPP351C500E ZPP221C501E ZPP351E500E ZPP221E501E 120 ZPP351G500E ZPP221G501E 130 Tr-5C Tr+5C Max.
