NCP15XH103F03RC

When you’re picking a capacitor, this one is a solid choice. It’s a multilayer ceramic capacitor (MLCC) that’s great for decoupling and filtering in your circuits. With a capacitance of 10nF, it’s perfect for high-frequency filtering tasks. The 50V voltage rating ensures it can handle moderate voltage applications without issue. The ±10% tolerance means you’ll have some slight variation, but nothing too drastic. Plus, the X7R dielectric ensures the capacitor stays stable over a wide temperature range from -55°C to 125°C. It’s packaged in the 1206 surface-mount size, which works well for compact designs. You’ll typically find this type of capacitor in power supply filters, RF circuits, and signal processing, helping reduce noise and keep your voltage steady.

NCP15XH103F03RC Equivalent

The first few recommended models are very similar to your original NCP15XH103F03RC and will typically work fine as direct replacements. But keep in mind, real-world scenarios might show slight differences—things like thermal response speed or long-term stability. To be safe, I suggest running some tests in your specific application.

However, the TDK NTCG104LH104JTDS is pretty different. Its resistance is 100kΩ with a B-value of 4250K, significantly off from your original choice. This type works best if you’re specifically aiming for a higher resistance sensor or different thermal characteristics. You’d definitely need to revisit and tweak your circuit to ensure it matches your performance goals.

NCP15XH103F03RC Thermistor Circuit Example

This circuit uses the NCP15XH103F03RC thermistor to detect temperature changes. The thermistor’s resistance decreases as the temperature rises, which is key for triggering the circuit. It’s paired with a 10kΩ resistor to form a voltage divider, and as the temperature shifts, the voltage across the thermistor changes, controlling the transistor Q1.

Q1 (BC547) acts as a switch that, when triggered by the voltage change, allows current to flow to Q2 (BC547). Q2, working as part of a Darlington pair, amplifies the current enough to light up the LED, signaling that the temperature has hit a specific threshold.

Make sure to place the thermistor in the area you want to monitor, and calibrate it so the circuit activates at the right temperature. The 390Ω resistor keeps the LED safe by limiting the current.

NCP15XH103F03RC Temperature Sensor Wiring

To wire the NCP15XH103F03RC thermistor, start by connecting one lead to the Vcc (usually 5V or 3.3V, depending on your microcontroller’s voltage). The other lead goes to an analog input pin on your microcontroller (like A0 on an Arduino), where it will read the voltage across the thermistor.

Next, connect a 10kΩ fixed resistor between the analog input pin and ground (GND). This resistor and the thermistor create a voltage divider. As the temperature changes, the resistance of the thermistor changes, which adjusts the voltage at the junction. The microcontroller reads this voltage and uses it to calculate the temperature.

The power supply comes from the microcontroller, either 5V or 3.3V. The ground from the microcontroller connects to the fixed resistor to complete the circuit. This setup allows the microcontroller to measure temperature by reading the voltage that changes as the thermistor’s resistance varies.

NCP15XH103F03RC in Arduino

To set up the thermistor, place it on the breadboard. One lead connects to 5V (Vcc) from the Arduino, and the other goes to the analog pin A0, where the voltage will be read. You’ll connect a 10kΩ resistor in series with the thermistor, creating a voltage divider. The resistor goes between A0 and ground (GND) on the breadboard.

Use a yellow wire to connect the thermistor to 5V, a red wire to link A0 to the voltage divider, and a black wire for the ground connection. The Arduino gets its power from the USB or external power supply, providing the 5V needed.

The thermistor’s resistance changes with temperature, and this affects the voltage that the Arduino reads at A0. The 10kΩ resistor helps convert these changes into a readable voltage.

NCP15XH103F03RC NTC Curve Characteristics

The NCP15XH103F03RC is a 10kΩ NTC thermistor, meaning its resistance decreases as the temperature rises. This feature is key for temperature sensing applications. At 25°C, the resistance is 10kΩ, and as the temperature goes up, the resistance drops significantly.

For example:

• At 0°C, it’s around 14kΩ.

• At 50°C, it’s about 5kΩ.

• At 100°C, it’s about 1.3kΩ.

This thermistor’s resistance changes are calculated using a formula called the B-parameter equation. The B coefficient is 3950K, which helps determine how resistance changes with temperature.

You’ll typically use this thermistor in temperature sensors, thermometers, or systems where temperature control is important. It works well in a voltage divider circuit with a known resistor, and the microcontroller can read the output to determine the temperature.
