NTC means Negative Temperature Coefficient: resistance decreases as temperature rises.<\/p>\n<h4>Specifications<\/h4>\n<ul>\n<li><strong>Resistance at 25 \u00b0C:<\/strong> 10 k\u03a9 \u00b11%<\/li>\n<li><strong>Material constant (B value):<\/strong> 3950 \u00b11%<\/li>\n<li><strong>Operating temperature range:<\/strong> \u221250 \u00b0C to +300 \u00b0C (as stated in the source listing; confirm the probe\u2019s actual rating)<\/li>\n<li><strong>Thermal response time:<\/strong> \u226420 seconds in air<\/li>\n<li><strong>Dissipation factor:<\/strong> approximately 7.5 mW\/K in air<\/li>\n<li><strong>Stability:<\/strong> high stability and durability (as stated in the listing)<\/li>\n<\/ul>\n<p><strong>Specification note:<\/strong> the source title and resistance specification say 10 k\u03a9, while the source description mentions \u201c10K\/100K\u201d and its keywords include \u201cNTC 100K.\u201d This translation retains 10 k\u03a9 from the listed specification; please verify the product value.<\/p>\n<h4>How it works<\/h4>\n<p>As the thermistor warms, its resistance falls. A voltage-divider circuit converts that resistance change into a voltage that a microcontroller or measurement system can read.<\/p>\n<h4>Applications<\/h4>\n<ul>\n<li>Household appliances, such as refrigerators, freezers, cookers and fryers<\/li>\n<li>Industrial and telecommunications systems: process control, heating and ventilation, fire alarms and battery thermal
