The **FCE-53-R** is a specific electronic component, typically identified as a **High-Density D-Sub Filter Connector** manufactured by companies like **Amphenol**. These parts are designed to provide both electrical connection and EMI (Electromagnetic Interference) filtering in a compact form factor. --- ### 1. Key Technical Specifications The FCE-53-R belongs to a family of filtered connectors designed to protect sensitive circuits from high-frequency noise. | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub (High Density) | | **Number of Positions** | 15 (Standard for Size 1 Shell) | | **Gender** | Receptacle (Socket) | | **Mounting Type** | Through-Hole / Right Angle | | **Filtering Method** | Capacitive Filter (C-Filter) | | **Contact Plating** | Gold over Nickel | | **Shell Material** | Steel (usually Tin or Zinc plated) | --- ### 2. Core Electronic Components The "filtered" aspect of the FCE-53-R involves integrated passive components built directly into the connector housing: * **Internal Capacitors:** The connector features ceramic planar arrays or individual chip capacitors connected between the signal pins and the ground shell. * **EMI/RFI Suppression:** It acts as a **Low-Pass Filter**, allowing low-frequency data signals to pass while shunting high-frequency interference (noise) to the chassis ground. * **Stress Isolation:** The internal components are often encapsulated in epoxy to protect the fragile ceramic filters from mechanical shock and soldering heat. --- ### 3. Application Use Cases Because this part combines a standard interface with noise suppression, it is commonly used in: 1. **Industrial Automation:** Preventing motor noise from corrupting sensor data. 2. **Medical Equipment:** Ensuring high signal integrity for diagnostic imaging. 3. **Telecommunications:** Reducing crosstalk in high-density rack systems. 4. **Military/Aerospace:** Providing robust connectivity in electrically "noisy" environments. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code usually breaks down as follows: * **FCE:** Filtered Connector Series. * **53:** Refers to the specific shell size and high-density pin configuration (15 pins). * **R:** Indicates **Right Angle** PCB orientation or **RoHS** compliance (depending on the specific manufacturer datasheet).
