The **15SRB1-R** is a specific type of power entry module, more commonly known as an **RFI/EMI Filter** (Radio Frequency Interference / Electromagnetic Interference filter). It is manufactured by TE Connectivity / Corcom. Below is a detailed breakdown of its specifications, components, and applications. --- ### 1. General Overview The 15SRB1-R is part of the **SR series**. These modules are designed to prevent unwanted electrical noise from entering a device via the power line, and conversely, to prevent the device from leaking noise back into the power grid. ### 2. Technical Specifications | Feature | Specification | |:---|:---| | **Current Rating** | 15 Amperes | | **Voltage Rating** | 120 / 250 VAC | | **Operating Frequency** | 50 / 60 Hz | | **Mounting Type** | Flange Mount (Screw-in) | | **Termination Style** | Spade Terminals (Faston) / Quick Connect | | **Inlet Type** | IEC 60320-1 C14 (Standard PC power plug) | | **Leakage Current** | Low Leakage (Safe for various environments) | ### 3. Internal Components A standard power line filter like the 15SRB1-R typically consists of a combination of passive electronic components housed in a shielded metal casing: 1. **Inductors (Chokes):** These provide high impedance to high-frequency noise while allowing the 50/60Hz power to pass through. 2. **Y-Capacitors:** Connected between the line/neutral and the ground. They bypass "Common Mode" noise to the earth. 3. **X-Capacitors:** Connected between the line and neutral. They filter "Differential Mode" noise across the power lines. 4. **Resistor:** Often includes a "bleeder resistor" to discharge the capacitors when the power is disconnected for safety. ### 4. Key Features * **Integrated Design:** Combines a power inlet and a filter into one unit, saving space and reducing wiring. * **Metal Housing:** The outer shell acts as a shield against radiated interference. * **Compact Form Factor:** Specifically designed for applications where space behind the panel is limited. ### 5. Common Applications * **Computing:** Power supplies for servers and workstations. * **Medical Equipment:** High-grade filtering to ensure patient safety and device accuracy. * **Industrial Electronics:** Protecting sensitive control circuits from factory floor electrical noise. * **Test & Measurement:** Ensuring clean power for high-precision laboratory instruments. ---
