pth8l series thermistor products ptc thermistor for circuit protection posistor protects circuit components at the load and power supply sides by reducing the current when abnormal current flows through the circuit. features posistor continues to protect a circuit until the abnormal current situation is corrected. posistor returns to the initial condition when the overcurrent is removed. no noise is emitted due to no contact. excellent durability posistor is resistant to mechanical vibrations and shocks due to solid element construction. non-contract design protects circuits quickly t bg bd ae bd bb as an bc ar ap am bg t ah ak ag af ae ad ac ab resistance?emperature characteristics application circuit transformer protection circuit (i) transformer protection circuit (ii) ?0 0 25 50 100 150 200 250 300 temperature (?) rate of resistance change (r/r25?) 10 5 10 4 10 3 10 2 10 1 10 ? pth8l 09 bd 2r2 n 2 b550 application diameter temperature resistance resistance voltage other overcurrent characteristics value tolerance specifications protection curie point (3-digit code) h: 25% ar: 120? bc: 90? m: 20% ba: 110? bd: 80? n: 30% bb: 100? part numbering system posistor posistor r l r b r e c r a power supply d c posistor power supply transistor protection circuit fluorescent lamp protection circuit posistor ch c c c r ss fluorescent lamp power source 552 cg01-j 100 80 60 40 20 0 -10 0 10 20 30 40 50 60 ambient temperature ( c) current (ma) protective threshold current trip current non operating current protective threshold current range
