The **FLCS-44-R** is an electronic component primarily classified as a **PLCC (Plastic Leaded Chip Carrier) Socket**. These parts are designed to provide a secure mechanical and electrical interface between an integrated circuit (IC) and a printed circuit board (PCB), allowing for easy replacement or testing of the chip without soldering the IC directly. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature typical of interconnect manufacturers (like Adam Tech or similar suppliers). | Feature | Specification | | :--- | :--- | | **Type** | PLCC Socket (Surface Mount or Thru-Hole) | | **Number of Pins** | 44 Pins | | **Pitch** | 1.27mm (0.050") | | **Contact Material** | Phosphor Bronze or Copper Alloy | | **Plating** | Tin (Standard) or Gold Flash | | **Insulator** | PPS or PBT (High-temperature plastic) | | **Mounting Style** | Thru-Hole (typically indicated by the suffix/series) | --- ### 2. Functional Components The FLCS-44-R consists of three primary sub-parts: 1. **The Insulator Body:** A square plastic housing with a center cutout. It is designed to withstand high temperatures during wave soldering. 2. **J-Lead Contacts:** The internal metal pins are shaped like a "J". These provide a high-pressure spring force against the leads of the PLCC chip to ensure a stable electrical connection. 3. **Polarization Features:** The corner of the socket is usually "chamfered" (flattened) to ensure the IC can only be inserted in the correct orientation, preventing reverse polarity damage. --- ### 3. Common Applications * **Legacy Computing:** Used for BIOS chips or Microcontrollers in older motherboards. * **Prototyping:** Ideal for development boards where the IC might need to be swapped or reprogrammed frequently. * **Automotive/Industrial:** Provides a rugged interface that can handle vibration while allowing for modular repairs. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by brand, the breakdown is generally: * **FLCS:** Series identifier (PLCC Socket). * **44:** Pin count (The chip will have 11 pins per side). * **R:** Often denotes **RoHS Compliance** (Lead-free) or specific packaging (like "Reel" or "Tube").
