A Positive Temperature Coefficient (PTC) device is primarily used for overcurrent protection and temperature regulation in electrical circuits. It acts as a resistor that increases its resistance significantly when a certain temperature threshold is exceeded, thereby limiting the current flow and preventing overheating. PTC devices are commonly found in applications such as circuit protection, heating elements, and as resettable fuses in electronic devices. Their self-regulating nature makes them efficient and reliable for safeguarding sensitive components.

What is an application for a positive temperature coefficient ptc thermistor device?
A positive temperature coefficient (PTC) thermistor is commonly used in overcurrent protection applications, such as in electrical circuits and power supplies. When the temperature rises due to excessive current, the resistance of the PTC thermistor increases sharply, limiting the current flow and preventing damage to the circuit. Additionally, PTC thermistors are utilized in heating applications, such as self-regulating heating elements, where they provide consistent temperature control by adjusting resistance with temperature changes.
What is the market cap for PTC Inc PTC?
As of July 2014, the market cap for PTC Inc. (PTC) is $4,464,804,555.68.
What is the symbol for PTC Inc in NASDAQ?
The symbol for PTC Inc. in NASDAQ is: PTC.
What is a PTC Relay?
A PTC relay, also known as a positive temperature coefficient relay, is a type of protective device used in refrigerators and air conditioners to protect the compressor from overheating. It uses a thermistor that increases its resistance with temperature, helping to regulate the current flowing to the compressor and prevent damage.
Who publishes MathCad?
MathCad is published by PTC, Incorporated. PTC used to be known as Parametric Technology Corporation. MathCad was written by Allan Razdow of MIT.
Why was untreated paper used in the PTC taste test?
Untreated paper was used in the PTC taste test because it is an easy and cost-effective way to deliver the chemical PTC to the taste buds. PTC is bitter and people have varying sensitivity to it, allowing researchers to study how genetics influence taste perception.
What does a ptc relay do?
A PTC (Positive Temperature Coefficient) relay is an electronic component that uses a positive temperature coefficient thermistor to control electrical circuits. As the temperature increases, the resistance of the PTC device rises sharply, which can interrupt the flow of current and protect circuits from overcurrent conditions. When the temperature drops, the resistance decreases, allowing current to flow again. This makes PTC relays useful for applications requiring thermal protection and resettable fuses.
What does PTC mean in a court?
Pre -Trial Conference.
When was PTC Alliance created?
PTC Alliance was created in 1924.
What is 14K PTC?
"14K PTC" typically refers to a 14-karat gold piece of jewelry that is plated with a thin layer of platinum to give it added durability and shine. PTC stands for platinum coating, which is often used to enhance the appearance and longevity of gold jewelry.
Can two parents who can taste ptc have a child who can't?
Yes, it is possible for two parents who can taste PTC to have a child who cannot taste PTC. PTC taste sensitivity is determined by genetics, and it is possible for genetic variations to result in a child with different taste abilities than their parents.
