The **15SRBP-R** is a specific type of power entry module, typically manufactured by **TE Connectivity / Corcom**. It is designed to combine an IEC power inlet with an RFI (Radio Frequency Interference) filter. --- ### ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Part Number** | 15SRBP-R | | **Current Rating** | 15 Amps | | **Voltage Rating** | 120 / 250 VAC | | **Filter Type** | RFI Filter (General Purpose) | | **Connector Type** | IEC 60320-1 C14 (Male Inlet) | | **Mounting Style** | Snap-in | | **Termination** | Spade Terminals (6.3mm / .250") | | **Operating Frequency** | 50 / 60 Hz | --- ### ## Key Features and Components 1. **Integrated RFI Filter**: The "SR" series is known for its small footprint. The internal circuitry suppresses electromagnetic interference (EMI) coming from the AC line into the device, or prevents high-frequency noise generated by the device from escaping into the power grid. 2. **Snap-In Design**: The "S" in the prefix usually denotes a snap-in mounting style, allowing for quick assembly into a rectangular cutout in a metal or plastic chassis without the need for screws. 3. **Resistor (Bleeder)**: The **-R** suffix often indicates the inclusion of a **bleeder resistor**. This safety component discharges the filter capacitors when the power is disconnected, preventing a residual electric shock hazard at the plug pins. 4. **Compact Construction**: These modules are designed to save space, combining a standard power plug and a filter into a single metal-shielded housing. --- ### ## Internal Schematic Representation Internally, these modules typically contain a network of: * **X-Capacitors**: To suppress line-to-line interference. * **Y-Capacitors**: To suppress line-to-ground interference. * **Inductors (Chokes)**: To provide high impedance to high-frequency noise. * **Bleeder Resistor**: Connected across the AC lines. --- ### ## Common Applications * Medical Equipment (Low leakage versions) * Computers and Peripheral devices * Industrial Controllers * Telecommunications equipment * Test and Measurement instruments
