EPCOS - TDK Electronics B58031I5105M062 Environmental and export classification status description

TDK B58031I5105M062 The B58031I5105M062 is a specific product from TDK Corporation's selection of capacitors, particularly a type of NTC (Negative Temperature Coefficient) thermistor. NTC thermistors are resistors with a resistance that decreases with increasing temperature, making them useful in various temperature sensing and compensation applications. Functions 1. Temperature Sensing: The main function is to measure temperature by changing its resistance based on thermal fluctuations. 2. Temperature Compensation: It can be used to correct for temperature variations in circuitry. 3. Protection: Helps in over-temperature protection of devices. 4. Monitoring: Often used in monitoring systems for environmental and operational conditions. Applications 1. Power Supplies: Used for inrush current limiting in power supply circuits. 2. Consumer Electronics: Found in devices like refrigerators, air conditioners, and temperature controllers. 3. Automotive: Used in engine control units (ECUs) for monitoring temperature. 4. HVAC Systems: For regulating temperature and assisting in energy management. 5. Industrial Equipment: Monitoring and controlling the temperature in machinery. Alternative Components - PTC (Positive Temperature Coefficient) Thermistors: These are used in some applications where resistance increases with temperature, offering opposite characteristics to NTC thermistors. - RTD (Resistance Temperature Detectors): These are more precise but often costlier alternatives that work on a similar principle of resistance change with temperature. - Silicon Temperature Sensors: These provide digital outputs and may integrate with microcontroller systems more easily. Embedded Modules Incorporating the B58031I5105M062 into larger systems can be done using: - Thermal management modules: Integrated circuits with built-in thermal compensation using NTCs. - Controller modules: Microcontrollers that can read input from NTC thermistors for smart home or HVAC applications. - IoT Sensors: Embedding NTCs into IoT devices for real-time temperature monitoring and data logging. Related Q&A 1. Q: What is the typical resistance value of the B58031I5105M062 at 25°C? - A: The typical resistance value of this NTC thermistor at 25°C is 10 kΩ. 2. Q: How does temperature affect the resistance of NTC thermistors like the B58031I5105M062? - A: As temperature increases, the resistance of NTC thermistors decreases exponentially, which makes them ideal for precise temperature sensing. 3. Q: Can the B58031I5105M062 be used in a circuit for over-temperature protection? - A: Yes, it can be used in conjunction with a circuit that monitors resistance changes, allowing it to trigger protective measures when predefined temperature limits are exceeded. 4. Q: What is the primary operational drawback of NTC thermistors such as the B58031I5105M062? - A: One drawback is that they have a non-linear resistance-temperature characteristic, which requires calibration or linearization in applications for high precision. 5. Q: In what kind of applications would you prefer using PTC thermistors over NTC thermistors? - A: PTC thermistors are preferred in applications requiring self-resetting over-current protection, such as in fuses and for current limiting in power circuits. This overview should give you a clear understanding of the B58031I5105M062 from TDK Corporation within its context in the capacitors category.
