The **4116R-3-R2** is a specific model of a **Resistor Network** (also known as a Resistor Array) manufactured by Bourns. These components are used to condense multiple resistors into a single package to save space on a Printed Circuit Board (PCB). --- ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Bourns Inc. | | **Series** | 4100R Series | | **Package Type** | DIP (Dual In-line Package) | | **Number of Pins** | 16 Pins | | **Circuit Type** | -3 (Isolated) | | **Resistance Value** | Defined by "R2" (Variable - see decoding) | | **Tolerance** | ±2% | | **Power Rating** | 2.25 Watts (Total Package) | --- ### 2. Decoding the Part Number: 4116R-3-R2 The part number is a code that identifies the physical and electrical characteristics: * **41**: Represents the Molded DIP series. * **16**: Indicates the number of pins (16 pins). * **R**: Specifies the low-profile package height. * **-3**: **Circuit Configuration (Isolated).** In this setup, the package contains 8 individual resistors. Each resistor is independent and has its own two dedicated pins (e.g., Pin 1-16, Pin 2-15). * **-R2**: This suffix typically refers to a specific resistance value or a custom configuration within the manufacturer's catalog (Standard R2 often implies a specific value like 220 Ohms or a placeholder for custom values). --- ### 3. Circuit Internal Layout (-3 Configuration) The **-3 configuration** is one of the most common for the 4116R series. Unlike "Bussed" networks where all resistors share a common pin, the **Isolated** network looks like this: ```text Pin 1 ---[Resistor 1]--- Pin 16 Pin 2 ---[Resistor 2]--- Pin 15 Pin 3 ---[Resistor 3]--- Pin 14 ... and so on up to 8 resistors. ``` --- ### 4. Key Advantages 1. **Space Efficiency:** It replaces 8 individual discrete resistors with a single component. 2. **Assembly Speed:** Faster pick-and-place or manual insertion during manufacturing. 3. **Matching:** Because the resistors are manufactured on the same substrate, they have better temperature coefficient matching than random discrete resistors. --- ### 5. Common Applications * **Line Termination:** Terminating data lines to prevent signal reflections. * **LED Current Limiting:** Providing consistent resistance for a bank of 8 LEDs. * **Pull-up/Pull-down:** Creating logic level stability for a 8-bit bus. ---
