The **FCE-16-R** is a specific electronic component belonging to the family of **D-Subminiature EMI/RFI Filter Adapters**, typically manufactured by companies like **Amphenol (Canada) Corp**. Below is a detailed technical breakdown of its electronic parts and specifications. --- ### 1. General Overview The FCE-16-R series is designed to provide high-frequency noise suppression at the Input/Output (I/O) interface. It acts as an adapter that plugs into a standard D-Sub connector to filter out electromagnetic interference (EMI) before it enters or leaves the system. ### 2. Technical Specifications The "16" in the part number often refers to the specific filter configuration or capacitance value, while the "R" typically denotes RoHS compliance. | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature Filter Adapter | | **Circuit Type** | C-Filter (Capacitive) | | **Voltage Rating** | 200V DC / 120V AC | | **Current Rating** | 5 Amps | | **Dielectric Withstanding Voltage** | 500V DC | | **Insulation Resistance** | 3000 MΩ minimum | | **Operating Temperature** | -40°C to +85°C | --- ### 3. Internal Electronic Construction The device is not just a passive pass-through; it contains internal components integrated into the connector shell: * **Planar Capacitor Array:** The heart of the FCE-16-R is a ceramic planar array. This is a multi-layer ceramic block with holes for each pin. It provides high-capacitance filtering in a very small footprint. * **Filter Pins:** Each pin is surrounded by the capacitive material. When high-frequency noise travels along the pin, the capacitor shunts that noise to the "ground" (the metal shell of the connector). * **Conductive Epoxy/Spring:** Used to ensure a low-impedance electrical connection between the capacitor array and the outer metal shell. * **Ferrite Inductors (Optional):** Some variations in this series include ferrite beads around the pins to create a "Pi" or "L" filter for more aggressive noise suppression. --- ### 4. Part Number Breakdown (FCE-16-R) While exact nomenclature can vary by manufacturer, it generally follows this logic: 1. **FCE:** Filtered Connector Extension/Adapter. 2. **17 / 16:** Specific series code representing the shell size (e.g., 9, 15, 25, or 37 pins) and the capacitance value (often ranging from 470pF to 47,000pF). 3. **R:** **RoHS Compliant**. This indicates the part is manufactured without lead, cadmium, or other restricted hazardous substances. --- ### 5. Application Use Cases * **Industrial Control:** Preventing electrical noise from motors or relays from corrupting data signals. * **Telecommunications:** Ensuring signal integrity in high-speed data transmission. * **Medical Equipment:** Reducing EMI to comply with strict EMC (Electromagnetic Compatibility) standards. ---
