The PRTC19.94TR1800WMCX is a positive temperature coefficient (PTC) thermistor manufactured by AVX Corp/Kyocera Corp. It is designed to protect circuits from overcurrent conditions by increasing resistance when the temperature rises due to excessive current flow. This device is a surface mount device (SMD) and offers reliable circuit protection in a compact package.

Applications:

• Overcurrent protection in automotive electronics
• Protection of sensitive electronic components in industrial equipment
• USB port protection
• Power supply protection
• Motor overload protection

Features:

• Positive Temperature Coefficient (PTC) characteristic
• Surface Mount Device (SMD) package
• Fast trip time
• Low resistance in normal operation
• High resistance in tripped state
• Compact size

Benefits:

• Provides reliable overcurrent protection
• Resettable protection: automatically returns to normal operation after the fault is cleared
• Reduces the risk of fire and damage to electronic components
• Enhances the safety and reliability of electronic devices
• Easy to integrate into circuit designs due to its SMD package

Additional Details:

The PRTC19.94TR1800WMCX has a resistance of 19.94 Ohms. The specific tripping current and hold current ratings should be verified via the manufacturer's datasheet. The operating temperature range is typically between -40°C and +85°C. The dimensions and other physical characteristics are available in the datasheet.

This PTC thermistor is RoHS compliant and halogen-free. Proper application and derating guidelines should be followed for optimal performance and reliability. Consult the datasheet for detailed electrical characteristics, thermal derating curves, and soldering recommendations.
