The **R2K-1-R** is a specific electronic component belonging to the family of **Resistor Networks** (specifically a Resistor Array). These are commonly used in high-density circuit designs to save space and simplify manufacturing. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for this series (often associated with manufacturers like Susumu or similar precision SMD resistor brands), here are the typical specifications: | Parameter | Specification | | :--- | :--- | | **Component Type** | SMD Resistor Array / Network | | **Resistance Value** | 2k Ohms (indicated by "2K") | | **Number of Resistors** | Usually 2 or 4 (depending on package size) | | **Tolerance** | Generally ±0.1% to ±0.5% (Precision type) | | **Package Style** | 0603 or 1206 Chip Array (R-type) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Functional Description The R2K-1-R is designed to provide multiple resistors within a single physical package. This is achieved through thin-film or thick-film deposition on a ceramic substrate. * **Network Configuration:** Usually configured as "Isolated" resistors, meaning each resistor in the package has its own two terminals and does not share a common bus. * **The "-R" Suffix:** In modern electronics, this suffix almost universally denotes **RoHS Compliance** (Restriction of Hazardous Substances) or **Tape and Reel** packaging for automated pick-and-place assembly. --- ### 3. Common Applications Because these parts are often high-precision, they are used in circuits where matching and stability are critical: 1. **Voltage Dividers:** Since the resistors are manufactured on the same substrate, they have excellent "tracking" properties (they change resistance at the same rate when temperature shifts). 2. **Pull-up/Pull-down Resistors:** Used for digital I/O lines to ensure signals stay at a logic high or low. 3. **Operational Amplifier Feedback:** Providing precise gain control in analog signal processing. 4. **Space-Constrained PCB Designs:** Replacing multiple individual 0402 or 0603 resistors with a single array to reduce the "BOM" (Bill of Materials) count. --- ### 4. Identification Code Breakdown | Part Segment | Meaning | | :--- | :--- | | **R** | Component Category (Resistor) | | **2K** | Resistance value (2,000 Ohms) | | **1** | Designator for specific tolerance or power rating | | **R** | RoHS Compliant / Reel Packaging |
