The POZ3AN-1-501N-T00 is a positive temperature coefficient (PTC) thermistor manufactured by Murata Electronics North America. PTC thermistors are thermally sensitive resistors that exhibit a large increase in resistance when their body temperature exceeds a certain point. This characteristic makes them suitable for overcurrent protection, inrush current limiting, and self-regulating heating applications.

Applications

• Overcurrent protection in electronic circuits
• Inrush current limiting in power supplies and motor drives
• Self-regulating heaters for automotive and industrial applications
• Battery charging circuits
• Telecommunications equipment

Features

• Positive temperature coefficient (PTC) characteristic
• Surface mount package
• Fast response time
• Compact size
• High reliability
• RoHS compliant

Benefits

• Overcurrent Protection: Protects circuits from damage due to excessive current.
• Inrush Current Limiting: Prevents damage to components during power-up.
• Self-Regulating Heating: Provides stable and controlled heating without the need for complex control circuitry.
• Space Saving: The small size allows for use in compact electronic devices.
• Reliable Performance: Designed for long-term stability and reliability.

Specifications

The POZ3AN-1-501N-T00 has a resistance of 500 ohms at 25°C. It has a switching temperature (Curie temperature) at which the resistance rapidly increases. The exact temperature can vary based on application requirements. It is available in a surface mount package for automated assembly. The operating temperature range is typically from -40°C to +125°C, but it is essential to consult the datasheet for precise values.

This PTC thermistor is commonly used in a variety of electronic circuits to provide overcurrent protection and inrush current limiting. Its fast response time and compact size make it a popular choice for many applications. The self-regulating heating feature is particularly useful in applications where precise temperature control is required.
