The NCP03WF104J05RL is a thermistor manufactured by Murata Electronics North America. It is a negative temperature coefficient (NTC) thermistor, meaning its resistance decreases as its temperature increases. This characteristic makes it useful for temperature sensing, temperature compensation, and inrush current limiting.

Applications

• Temperature sensing in electronic devices: Used to monitor and control temperature in circuits and systems.
• Temperature compensation in circuits: Compensates for the effects of temperature on other components in a circuit.
• Inrush current limiting: Limits the amount of current that flows into a circuit when it is first turned on.
• Overcurrent protection: Provides overcurrent protection for circuits and systems.
• Battery chargers: Temperature sensing and compensation in battery charging circuits.
• LED lighting: Temperature protection for LED drivers.

Features

• Negative Temperature Coefficient (NTC): Resistance decreases as temperature increases.
• Small Size: Compact design for use in space-constrained applications.
• High Accuracy: Provides accurate temperature sensing.
• Wide Temperature Range: Operates over a broad temperature range.
• Excellent Stability: Maintains stable performance over time.
• RoHS Compliant: Compliant with Restriction of Hazardous Substances directive.

Benefits

• Accurate Temperature Measurement: Provides precise temperature readings for reliable control and monitoring.
• Circuit Protection: Protects circuits from damage due to overtemperature or overcurrent conditions.
• Improved Circuit Performance: Compensates for temperature-related variations in circuit components.
• Enhanced Reliability: Ensures stable and reliable operation of electronic devices.
