The **15SRB8-R** is a specialized electronic component categorized as a **Power Line Filter** (also known as an EMI/RFI Filter). It is designed to suppress electromagnetic interference on AC power lines to ensure electronic equipment operates without noise and complies with emission standards. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the 15SRB8-R: | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / Corcom | | **Current Rating** | 15 Amperes | | **Voltage Rating (AC)** | 120 / 250 VAC | | **Mounting Type** | Panel Mount (Snap-in) | | **Termination Style** | Spade/Solder Terminals (Quick Connect) | | **Filter Type** | Single Phase / RFI Filter | | **Operating Frequency** | 50 / 60 Hz | | **Leakage Current** | Low Leakage (Medical/Standard applications) | --- ## 2. Core Components and Functionality The "SRB" series typically utilizes a combination of internal passive components to filter high-frequency noise: 1. **Inductors (Chokes):** Used to block high-frequency common-mode noise while allowing the 50/60Hz power frequency to pass. 2. **X-Capacitors:** Connected across the line and neutral to suppress differential-mode interference. 3. **Y-Capacitors:** Connected between the lines and the ground to divert common-mode noise to the earth. 4. **Resistor:** Often includes a discharge resistor to bleed off stored energy from the capacitors when power is disconnected for safety. --- ## 3. Application and Use Cases The 15SRB8-R is commonly found in environments where electrical noise can cause data errors or equipment malfunction. * **Computing & Networking:** Servers and workstations where stable power is critical. * **Industrial Equipment:** Control panels and automation machinery. * **Medical Devices:** Versions with low leakage current are used to prevent shocks to patients/operators. * **Telecommunications:** Protection for sensitive signal processing hardware. --- ## 4. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **15:** Indicates the current rating (15 Amps). * **SRB:** Refers to the series (Compact RFI Filters for power entry). * **8:** Usually denotes the specific termination or mounting style (e.g., specific flange or snap-in dimension). * **-R:** Often signifies compliance with specific environmental standards (like RoHS) or a specific revision of the hardware.
