The characteristics and quality of the components directly determinePTC HeaterThe performance of the PTC heater is very important, so it is necessary to carefully select the PTC heater element. The PTC heater elements in the thermostatic heater products on the market are generally high-temperature elements with a Curie temperature higher than 120°C. Compared with low-temperature elements, there are very large differences in manufacturing process and performance.

Want better heating performance and safer heating environment, we choosePTC HeaterWhen choosing components, you need to consider the following parameters:

(1) Normal temperature resistor R25: For 110~220V, R25 is generally 100Ω~10KΩ, and for 6~24V, R25 is 0.5~5Ω. Generally speaking, the smaller R25 is, the larger the starting current is, the faster the heating is, the higher the power is, but the voltage resistance is very poor.

(2) Curie temperature TC should be moderate: Under certain conditions, increasing TC will increase the power consumption of the heater, but too high TC (over 260°C) will make the electrodes of the PTC element easy to age, significantly shorten the life, and often accompanied by thermal breakdown. Therefore, PTC heating elements with a Curie temperature below 260°C are usually selected.

(3) High withstand voltage: Ensure at least twice the applied voltage to prevent electrical breakdown.

(4) The temperature coefficient of the resistor must be large: generally greater than 14, to ensure that it is less affected by changes in ambient temperature.

(5) The initial surge current should be moderate: Generally speaking, the surge current should be less than twice the stable operating current.

PTC HeaterIt heats up quickly and is conveniently designed. It can be used in any power range, and the safety hazard is relatively small.
