The **10BOS-1-R** is a specific electronic component typically identified as a **Power Line Filter** or an **EMI/RFI Filter** manufactured by companies like **Delta Electronics**. These parts are designed to suppress electromagnetic interference (EMI) between the power line and the electronic equipment. --- ## 1. Technical Specifications Below are the general specifications for the 10BOS-1-R series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Single-Phase EMI Filter | | **Rated Voltage** | 115/250 VAC | | **Rated Current** | 10 Amperes | | **Operating Frequency** | 50/60 Hz | | **Leakage Current** | ~0.45 mA (at 115V) / ~0.80 mA (at 250V) | | **Termination Style** | Solder Lug / Faston terminals | | **Mounting Type** | Panel Mount (Snap-in or Screw) | --- ## 2. Key Internal Components An EMI filter like the 10BOS-1-R consists of a passive network of components: * **X-Capacitors:** Connected across the lines (Line to Neutral) to suppress differential mode interference. * **Y-Capacitors:** Connected from the lines to the ground to suppress common-mode interference. * **Common Mode Choke:** An inductor with two windings on a single core that provides high impedance to common-mode noise while allowing the power current to pass. * **Bleeder Resistor:** Often included to discharge the capacitors when power is disconnected for safety. --- ## 3. Applications The 10BOS-1-R is commonly used in environments where electronic noise could interfere with sensitive circuitry or where regulatory compliance (like FCC or CE) is required. 1. **Industrial Equipment:** Control systems and power supplies. 2. **Medical Devices:** High-reliability filtering for diagnostic tools. 3. **Consumer Electronics:** Computers, monitors, and office automation. 4. **Test & Measurement:** Ensuring clean power for precise instruments. --- ## 4. Connection Diagram (General) The typical wiring configuration for this part follows a standard filter topology: ```text LINE (L) ----[ Inductor ]----+---- LOAD (L') | [X-Capacitor] | NEUTRAL (N) --[ Inductor ]----+---- LOAD (N') | [Y-Capacitors] | GROUND ```
