Based on the part number **61D-082-R**, this component is typically identified as a **high-voltage, high-frequency flyback transformer** or a specific **SMPS (Switched-Mode Power Supply) transformer** often used in consumer electronics, such as televisions or power adapters. --- ### 1. General Specifications While specific datasheets can vary by manufacturer (often associated with brands like ZETTLER or custom OEM suppliers), components in this series generally follow these parameters: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | Flyback / SMPS Transformer | | **Inductance Range** | 500µH - 1.5mH (Primary) | | **Isolation Voltage** | 3000V AC - 4000V AC | | **Operating Frequency** | 20kHz - 150kHz | | **Termination Style** | Through-Hole (THT) | | **Compliance** | RoHS Compliant ("-R" suffix) | --- ### 2. Technical Functionality The **61D-082-R** functions as the heart of a power conversion circuit. Its role involves: * **Energy Storage:** Unlike standard transformers, flyback transformers store energy in their magnetic field during the "ON" cycle of the switching transistor and release it to the secondary side during the "OFF" cycle. * **Galvanic Isolation:** It provides a safety barrier between the high-voltage AC input (Mains) and the low-voltage DC output (Logic/Load). * **Voltage Regulation:** By varying the duty cycle of the input pulse, the transformer helps maintain a steady output voltage even if the input fluctuates. --- ### 3. Application Areas These parts are commonly found in the following devices: 1. **LCD/LED Monitors:** Powering the logic boards and backlight inverters. 2. **Industrial Controllers:** Small-form-factor power supplies for PLC modules. 3. **Home Appliances:** Control boards for washing machines or microwave ovens. 4. **Battery Chargers:** High-efficiency charging circuits. --- ### 4. Interpretation of Suffixes * **61D:** Series designation (often indicates the core size/geometry, like EFD or EE cores). * **082:** Specific winding configuration or turn-ratio code. * **-R:** Generally indicates **RoHS Compliance** (Restriction of Hazardous Substances), meaning the part is lead-free. --- ### 5. Troubleshooting Tips If you are testing this component on a PCB: * **Check Continuity:** Measure the primary and secondary windings for open circuits. * **Visual Inspection:** Look for cracks in the ferrite core or discoloration (browning) of the plastic bobbin, which indicates overheating. * **Shorts:** Use an LCR meter to check for "shorted turns," which can cause the power supply to enter "hiccup mode."
