The **04BEEG3F-R** is a high-performance **Power Entry Module (PEM)** manufactured by Delta Electronics. It is primarily used to integrate power connection, filtering, and safety features into a single compact component for electronic devices. --- ## 1. Component Overview This part belongs to the **B Series** of Delta’s EMI filters. It is an IEC inlet filter designed to suppress electromagnetic interference (EMI) and protect sensitive electronics from noise on the AC power line. ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Delta Electronics | | **Part Number** | 04BEEG3F-R | | **Rated Current** | 4 Amperes | | **Rated Voltage** | 115 / 250 VAC | | **Operating Frequency** | 50/60 Hz | | **Leakage Current** | 0.45 mA max @ 250V / 0.25 mA max @ 115V | | **Mounting Type** | Flange Mount (Screw-in) | | **Termination Style** | Solder Lug / Faston Terminals | --- ## 2. Integrated Features The "04BEEG3F-R" is a multi-functional component consisting of: 1. **IEC 60320-1 C14 Inlet:** The standard male socket used for most computer and laboratory power cords. 2. **EMI Filter:** An internal network of inductors (chokes) and capacitors (X and Y caps) that filters out high-frequency noise. 3. **Fuse Holder:** Includes a compartment for a **5x20mm fuse** (usually double-fused for European standards or single-fused, depending on configuration). 4. **Bleeder Resistor:** (Indicated by the "R" suffix) Helps discharge internal capacitors quickly when power is disconnected for safety. --- ## 3. Pinout and Internal Circuitry The internal circuit generally follows a "Pi" or "L" filter configuration: * **Line (L) & Neutral (N):** Connected through the fuse to the inductive coil. * **Earth (G):** Connected to the metal casing for grounding. * **Cx Capacitors:** Filter differential mode noise (between L and N). * **Cy Capacitors:** Filter common mode noise (between L/N and Ground). --- ## 4. Typical Applications Because of its 4A rating and integrated filtering, this part is commonly found in: * Medical equipment (low leakage versions). * Test and measurement instruments. * Professional audio/video gear. * Industrial automation controllers. * Desktop power supplies. ---
