The **MHO361FCG-R** is a specific surface-mount electronic component, typically categorized as a **Metal Oxide Varistor (MOV)** or a high-power resistor/thermistor depending on the specific manufacturer's series (commonly associated with protection devices). Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview The "MHO" series generally refers to high-voltage or high-surge protection components designed for surface-mount technology (SMT). These are critical for protecting sensitive downstream circuitry from voltage spikes and transients. ### 2. Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Metal Oxide Varistor (MOV) / Surge Protector | | **Mounting Type** | SMD (Surface Mount Device) | | **Package/Case** | 361 (Specific proprietary footprint) | | **Material** | Metal Oxide (Zinc Oxide based) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | | **Operating Temp** | -40°C to +85°C (Standard industrial range) | ### 3. Key Electronic Functions * **Voltage Clamping:** It acts as a variable resistor. When voltage exceeds a specific threshold, its resistance drops sharply, shunting the excess current to ground or away from the load. * **Transient Suppression:** Protects against Lightning surges, ESD (Electrostatic Discharge), and inductive load switching. * **Energy Absorption:** High capacity for absorbing energy (measured in Joules) without destroying the component. ### 4. Decoding the Part Number While specific to the manufacturer (often associated with brands like Bourns or specialized Chinese power component firms), the code can generally be broken down as follows: 1. **MHO:** Series prefix (Metal Oxide family). 2. **361:** Refers to the physical dimensions or the specific voltage rating (e.g., 360V nominal). 3. **FCG:** Designates the tolerance, packaging style, or terminal plating. 4. **-R:** Standard industry suffix for **RoHS Compliant** (Lead-free). --- ### 5. Common Applications * **Power Supplies:** Used in the input stage of AC/DC converters. * **LED Drivers:** Protecting high-brightness LEDs from grid fluctuations. * **Smart Meters:** Ensuring longevity against line surges. * **Consumer Electronics:** Chargers, adapters, and home appliances.
