TJD series

■ TJD Series（NTC Thermistor with Polyamide Film）

►INTRODUCTION：

TJD series insulation film NTC thermistor is made by whole-newly technique, and it has the virtue of novel configuration, high

reliability and good coherence. It can be used in such occasions as temperature measurement﹑control and compensation.

►APPLICATION：

Computer, Printer, Home Appliances, and so on.

►CHARACTERISTIC：

♦Insulation film coated, rapid response and high sensitivity

♦High stability and reliability

♦Superior insulation

♦High precision of resistance value

♦It is possible to use with safety in ambience that might contact with electrodes

♦So small, light and solid in structure as to be convenient for auto mounting (to a printed circuit board)

►MAIN TECHNOLOGY PARAMETER：

♦Rated zero power resistance @25℃ (R25℃): 10KΩ ～ 100KΩ

♦Allowance tolerance of R25℃: F±1%﹑G±2%﹑H±3%﹑J±5%

♦Range of B value (B25/50℃): 3380K; 3950K

♦Allowance tolerance of B-value: E±0.5%﹑F±1%﹑G±2%

♦Dissipation coefficient: 0.7mW/℃ (in still air)

♦Thermal time constant:≦5S (in still air)

♦Operating temperature: -30 ～ +125℃

♦Rated power: ＜3.5mW

►PART NO.：

►DIMENSION(mm)：

Total Length (4 types): 18mm﹑25mm﹑50mm﹑75mm

●NOTICE：

(1) Don’t fold lead frame of thermistor at random in case of bad resistance value caused by the strip between chip and

lead frame;

(2) Don’t let temperature exceed 300℃ when soldering, and the time not exceed 0.5 second at better;

(3) Use heat wind gun when adding heat-shrink tube, the temperature should be controlled by 120℃;

(4) Use constant temperature iron when soldering, the head of iron should be flat; one hand takes thermistor,

the other takes wire and doing contact soldering, it can enhance manufacture efficiency and shorten the soldering time;

(5) Special notice: don’t touch chip by hands (namely the top of thermistor) !
