2. Epoxy resin G-108:GU-MZ, black
3. Al case housing: Φ3.5×30 + M8×1.25 mm
4. PTC Thermistor Tref=160℃±10℃, Surface temperature max 170℃
Feature Application
Thin rectangular PTC thermistor soldered with insulation cable, potted into threaded Al Housing. Threaded PTC Cartridge heating assembly suitable for pipe, tanks, vessel, container, equipment casings heating application. Threaded hex head design is ideal for tanks, vessel and pipe installation, as well as other industrial application, affords greater resistance to shock and vibration. Typical application such as automotive vehicles carburetor heating, water boiler, etc.

Reliability Data
| Test Item | Test conditions | Requests |
|---|---|---|
| Environmental variation | Temperature：80℃ (+0/-5) On：3 hours
Temperature：-15℃(±2) On: 3 hours With rapid change, change time <3 seconds, for 8 consecutive time. 24 hours at moiststatic room at 40℃, 100% relative humidity. |
PTC Thermistor characteristics curve shall not be changed.
No damage to the cables and resin. |
| Vibration Test | Sinusoidal vibration test last on 12 hours, according to 3 axis, composed the following A and B items
A) Frequency 10-60Hz, constant deplacement of 1.5mm from peak to peak. B) Frequency 60-200Hz, with accelerator 25g constant to peak. The brushing must occur in continuous way from minimum to maximum value, and vice versa, with a variation of 10Hz second. |
No visible mechanical damage. Function shall not be changed. |
| Control of the insulation layer | Apply voltage 500V, 50Hz to one of the 2 wires and containers for 1 second. | No damage, no discharge. |
PTC thermistor positive resistance vs. temperature R/T characteristic means that electric power consumed is automatically adapted to the ambient thermal conditions. At an ambient temperature significantly lower than Tref, i.e. with good heat transfer, the PTC thermistor has low resistance and consumes a relatively large amount of power. If the ambient temperature is significantly higher than Tref or heat transfer is restricted, the resistance of the PTC thermistor rises rapidly and power consumption is limited to a very low value.
Thanks to self-regulation properties, heating devices based on PTC thermistor technology can generally dispense with control and regulating components as well as with over-temperature protection, PTC thermistor heating elements are used wherever measurement and regulating equipment as well as heating devices must be housed in tight confines. There are no glowing parts, because the maximum surface temperature is limited by the R/T curve.
PTC thermistor heating pellet elements can be designed to be square, rectangular, disc round, ring or doughnut form, or PTC stone housed in aluminum, stainless steel, silicon casing.
