NTC Thermistor[5]

Updated: 2026-09-15

Overview

The NTCG104BF473JT1SX is a Negative Temperature Coefficient (NTC) thermistor manufactured with high-quality ceramic materials. These components exhibit a decrease in electrical resistance with increasing temperature, making them ideal for precise temperature measurement and control applications. With its compact SMD package, this thermistor is particularly suitable for modern electronic devices where space is at a premium. The component is RoHS compliant and designed for automated assembly processes, meeting the requirements of high-volume production environments.

Structure and Working Principle

The NTCG104BF473JT1SX consists of a sintered ceramic semiconductor material with metalized contacts for surface mounting. The ceramic composition is typically based on transition metal oxides that exhibit the NTC effect. When temperature increases, the mobility of charge carriers in the semiconductor material increases, resulting in lower resistance. This predictable resistance-temperature relationship allows the component to serve as an accurate temperature sensor when properly calibrated and incorporated into appropriate circuitry.

Key Features

This NTC thermistor offers a nominal resistance of 47kΩ at 25°C with a β value (material constant) of 4050K, providing excellent sensitivity across its operating range (-40°C to +125°C). The component features fast thermal response time due to its small thermal mass. The device is designed for stability and reliability, with minimal resistance drift over time. Its surface-mount package (0402 size) makes it suitable for high-density PCB designs, while the robust construction ensures mechanical durability during assembly and operation.

Application Areas

NTCG104BF473JT1SX finds extensive use in temperature monitoring and compensation circuits across various industries. In consumer electronics, it's commonly employed in smartphones, tablets, and wearables for battery temperature monitoring. Industrial applications include process control systems, HVAC equipment, and power supply units. The automotive sector utilizes these components for engine management systems, battery temperature monitoring in electric vehicles, and cabin climate control systems.

Maintenance and Precautions

When handling NTCG104BF473JT1SX thermistors, avoid applying mechanical stress to the component body as this may cause cracking or performance degradation. Storage should be in dry conditions to prevent moisture absorption. During circuit design, ensure the thermistor is not subjected to currents exceeding its rating, as self-heating effects may compromise measurement accuracy. For critical applications, consider periodic recalibration to maintain long-term measurement precision.

B2B Procurement Guide

For bulk procurement of NTCG104BF473JT1SX, verify the manufacturer's certification and quality control processes. Request detailed specifications including resistance tolerance, β value accuracy, and operating temperature range to ensure compatibility with your application. Consider lead times and minimum order quantities when planning purchases. Many distributors offer quantity price breaks, so evaluate your projected usage to optimize costs. Always request samples for testing before large-scale procurement to validate performance in your specific application environment.
