The **M5TS-50-R/Q** is a high-performance, precision temperature sensor designed for industrial and automotive applications. It is part of a specialized series (often associated with brands like Murata or specialized sensing manufacturers) known for its reliability in harsh environments. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | NTC Thermistor / Temperature Sensor | | **Resistance at 25°C** | 50 kΩ | | **Tolerance** | ±1% to ±3% (depending on specific R/Q sub-variants) | | **Operating Temperature** | -40°C to +125°C (standard range) | | **B-Constant** | Typically 3950K - 4250K (Beta value) | | **Mounting Type** | Surface Mount (SMD) or specialized leaded | --- ### 2. Electronic Characteristics #### A. Resistance-Temperature (R-T) Curve As an NTC (Negative Temperature Coefficient) device, its resistance decreases as the temperature increases. The "50" in the part number denotes the base resistance of **50,000 Ohms** at the standard reference temperature of 25°C. #### B. The "R/Q" Suffix Meaning In electronic component nomenclature, these suffixes often refer to: * **R:** Represents the packaging type (often "Tape and Reel" for automated pick-and-place machines). * **Q:** Often denotes a specific quality standard, such as **AEC-Q200** compliance, meaning the part is qualified for automotive use and can withstand significant vibration and thermal shock. --- ### 3. Circuit Integration To use this part in a circuit, it is typically implemented in a **Voltage Divider** configuration. ```cpp // Typical Arduino/Microcontroller Logic for M5TS series float Vout = analogRead(sensorPin) * (Vcc / 1023.0); float R_thermistor = R_fixed * (Vcc / Vout - 1.0); // Apply Steinhart-Hart equation to convert R_thermistor to Temperature ``` --- ### 4. Typical Applications 1. **Battery Management Systems (BMS):** Monitoring cell temperatures in EV batteries. 2. **Power Electronics:** Thermal protection for MOSFETs and IGBTs in inverters. 3. **Industrial HVAC:** Precise air and fluid temperature sensing. 4. **Consumer Electronics:** Overheat protection in high-speed charging bricks. ---
