The **MHR14FAJ-R** is a specific electronic component belonging to the **High Voltage Resistor** category, typically manufactured by companies like Murata or similar specialized passive component suppliers. These resistors are engineered to handle high potential differences and provide stable resistance in focus circuits for displays and high-voltage power supplies. --- ### 1. Key Technical Specifications The "MHR" series is generally characterized by its radial-lead design and high insulation resistance. | Parameter | Typical Value / Description | | :--- | :--- | | **Type** | Thick Film High Voltage Resistor | | **Resistance Value** | Often part of a focus pack or high-ohm divider | | **Configuration** | Radial Lead (Through-hole) | | **Coating** | Flame retardant epoxy/silicone | | **Main Application** | CRT Focus, Voltage dividers, High-voltage sensors | --- ### 2. Functional Characteristics High voltage resistors like the MHR14FAJ-R are built to withstand stresses that would destroy a standard carbon film resistor. * **Voltage Coefficient:** These parts are designed to minimize the change in resistance as the applied voltage increases. * **Stability:** They offer high stability under high humidity and high-temperature conditions. * **Safety Standards:** Usually UL-recognized or compliant with safety standards for high-voltage electronic equipment to prevent arcing or fire. --- ### 3. Pinout and Physical Structure While the internal schematic can vary, a typical "MHR" high-voltage part often follows this physical layout: ```text [ MHR14FAJ-R ] [ Body ] ---------------- | | | 1 2 3 (Radial Leads) ``` 1. **Lead 1:** Input (High Voltage) 2. **Lead 2:** Output / Tap (Intermediate Voltage) 3. **Lead 3:** Ground / Reference --- ### 4. Common Use Cases * **CRTs and Monitors:** Used in the "Focus" and "Screen" voltage adjustment circuits. * **Medical Equipment:** High-voltage power supplies for X-ray or imaging sensors. * **Industrial:** Measuring circuits for high-voltage power distribution.
