Normal questions in design and use

Thermal cutoff is a precise, stable safety component. The TCO would fuse abnormally due to improper design, installment and work environment. In order to use TCO properly, here comes some info for your reference.

Q: Technical Terms— What are the meanings of rated functioning temperature (Tf),Holding temperature(Th),Maximum temperature limit(Tm)?

A: Pls refer to the explanation of technical terms. (Explanation of nouns)

Q: Can thermal cutoff be used as current fuse?

A: The answer is NO. The TCO is only sensitive to temperature, Pls use the CTO strictly under the current and voltage which required.

Q: Why there is no conduct for TCO sometime after soldering? Why TCO can be open in test sometime after soldering and fixing? How to avoid these kinds of problems?

A: This is maybe caused by the temperature of welding. During the process of welding, the ambient temperature of TCO has reached the functioning point. As a result, the TCO could fuse or serious be damaged. The welding point is too close to the CTO, the welding time is too long, the temperature of welding is too high are some of the wrong behavior.

To reduce and avoid the damage made to the CTO, we suggest customers pay attention to the following tips:

1. The distance between the welding point and the body of the CTO should be more than 10mm. ( As showed in Figure4.)

2. The welding time should be less than 3s.

3. Welding fixture should be applied when the welding is manual. Such as cliping an aluminum block (or other metals which are good at dissipating the heat) with the lead wires to help dissipate the heat.

4. Immerse the lead wires into the cooling liquid (like alcohol) after the welding.
