The part number **03GENG3EW3E-R** refers to a specialized **EMI/RFI Power Line Filter** manufactured by **Delta Electronics**. This component is designed to suppress electromagnetic interference in electrical circuits, particularly for medical and industrial applications. --- ### 1. Technical Specifications The following table outlines the primary electrical and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Delta Electronics | | **Component Type** | EMI/RFI Filter (Power Entry Module) | | **Current Rating** | 3 Amperes | | **Voltage Rating** | 115 / 250 VAC | | **Operating Frequency** | 50/60 Hz | | **Mounting Type** | Snap-in / Panel Mount | | **Termination Style** | Wire Lead / Solder Lug | | **Leakage Current** | Low Leakage (Medical Grade) | --- ### 2. Breakdown of the Part Number The part number follows Delta's internal nomenclature for power components: * **03:** Indicates the **3 Ampere** current rating. * **GE:** Refers to the series type (General Purpose/Medical filters). * **NG3:** Specifies the physical housing and input/output configuration. * **EW:** Often denotes specific lead types or wiring (Extended Wires). * **-R:** Indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards. --- ### 3. Key Electronic Functions This part serves three primary functions within an electronic system: 1. **EMI Suppression:** It filters out high-frequency noise from the power line that could interfere with the device's sensitive internal electronics. 2. **RFI Shielding:** It prevents the device itself from emitting radio frequency interference back into the main power grid. 3. **Low Leakage Current:** Because this is an "E" type medical series filter, it is designed with very low leakage current to meet safety standards for medical equipment (where current leakage through the chassis must be minimal to ensure patient safety). ### 4. Common Applications * **Medical Equipment:** Patient monitors, diagnostic tools, and laboratory instruments. * **Power Supplies:** Switched-mode power supplies (SMPS) requiring noise regulation. * **Industrial Automation:** Control panels and sensitive sensor arrays. ---
