The Ntc 100k 3950 Datasheet is an essential document for anyone working with temperature sensing applications. It provides critical specifications and performance characteristics for a specific type of Negative Temperature Coefficient (NTC) thermistor. Understanding this datasheet is key to accurately measuring and controlling temperature in a wide array of electronic devices and systems.
Understanding the Ntc 100k 3950 Datasheet
At its core, an NTC thermistor is a resistor whose resistance decreases as its temperature increases. The "100k" in Ntc 100k 3950 refers to its nominal resistance of 100,000 ohms (or 100 kΩ) at a standard reference temperature, typically 25°C. The "3950" signifies the Beta (β) value, a crucial parameter that describes the thermistor's temperature-resistance relationship. A higher Beta value generally indicates a more sensitive thermistor over a specific temperature range. The accuracy and reliability of temperature readings heavily depend on selecting a thermistor with the correct specifications, as detailed in its datasheet.
These thermistors are widely employed for temperature measurement and compensation due to their:
- High sensitivity to temperature changes.
- Relatively low cost.
- Small physical size.
The Ntc 100k 3950 Datasheet will typically include information such as:
- Resistance at various temperatures.
- Beta (β) value and its tolerance.
- Maximum operating temperature and power dissipation.
- Response time.
- Tolerance specifications.
For example, a typical datasheet might present a table like this:
| Temperature (°C) | Resistance (kΩ) |
|---|---|
| 0 | ~325.5 |
| 25 | 100.0 |
| 50 | ~39.3 |
| 100 | ~9.3 |
This data allows engineers to create lookup tables or use mathematical formulas (often derived from the Steinhart-Hart equation, though simpler beta-based calculations are common for NTCs) to convert measured resistance values into accurate temperature readings. Applications range from simple digital thermometers and battery pack temperature monitoring to sophisticated industrial process control and automotive engine management systems. The Ntc 100k 3950 Datasheet is the definitive guide for integrating these versatile components into your designs.
