The **FPM3024H-R010CAP** is a specialized electronic component, typically categorized as a high-precision **Current Sense Resistor** (Shunt Resistor). These components are engineered to measure current flow by monitoring the voltage drop across a known resistance value. --- ### Technical Specifications Below is a breakdown of the typical electronic characteristics for this series: | Parameter | Value / Description | | :--- | :--- | | **Component Type** | Metal Plate Current Sense Resistor | | **Resistance Value** | 10 mΩ (milliohms) | | **Tolerance** | ±1.0% (Commonly denoted by 'F' or 'J' in related series) | | **Power Rating** | High Power (Typically 3W - 5W depending on thermal management) | | **Temperature Coefficient (TCR)** | Very Low (e.g., ±50ppm/°C) to ensure stability across temperatures | | **Construction** | Metal Alloy element with specialized terminations | --- ### Key Electronic Features #### 1. Low Resistance (10mΩ) The primary function of this part is to offer minimal resistance to the circuit to prevent power loss, while still providing a readable millivolt signal for an Integrated Circuit (IC) or Microcontroller to calculate amperage. #### 2. Kelvin Configuration (4-Terminal Potential) While the base part number often refers to the chip, the "FPM" series frequently utilizes a **Kelvin connection** design. This separates the current path from the voltage sensing path, eliminating the resistance of the lead wires from the measurement. #### 3. High Thermal Stability Because current sense resistors generate heat ($P = I^2R$), the FPM3024H is built using metal alloys that do not change resistance significantly as they get hot, ensuring the accuracy of the current reading remains constant. --- ### Circuit Applications This part is commonly found in the following electronic systems: * **Battery Management Systems (BMS):** Monitoring charge and discharge cycles in Lithium batteries. * **DC-DC Converters:** Providing feedback loops for current regulation. * **Motor Control:** Detecting over-current conditions to protect the motor windings. * **Power Supplies:** Monitoring output load levels. --- ### Identification Breakdown * **FPM:** Series identifier (Metal Plate/Power Shunt). * **3024:** Physical package size (Inches, e.g., 0.30" x 0.24"). * **R010:** Resistance value (0.010 Ohms or 10mΩ). * **CAP:** Packaging/Tolerance/Custom specification suffix.
