The term **415-R2** typically refers to a specific electronic component, most commonly a **Surface Mount Device (SMD) Resistor** or a specific **connector/RF adapter** series depending on the manufacturer (like Johnson/Cinch Connectivity). However, in the context of general electronics components, it most frequently denotes a **415 Ohm Resistor with a specific revision or tolerance code (R2).** --- ### 1. 415-R2 as a Resistor Component If "415-R2" is found on a schematic or a component reel, it breaks down as follows: | Feature | Specification | Description | | :--- | :--- | :--- | | **Resistance Value** | 415 Ohms | The primary resistance against current. | | **Code Interpretation** | 415 | Often represents $41 \times 10^0$ or a direct value in precision series. | | **Tolerance (R2)** | ±2% (Typical) | The "R2" suffix often denotes a 2% tolerance range in specific military or industrial coding. | | **Package Type** | SMD / Through-hole | Usually found in 0805, 1206, or axial lead formats. | ### 2. Cinch Connectivity / Johnson 415 Series In the realm of RF (Radio Frequency) engineering, the **415 series** is a well-known line of cable assemblies and connectors. * **Function:** Used for high-frequency signal transmission (SMA, MCX, MMCX connectors). * **R2 Designation:** Usually refers to a **Revision 2** design or a specific **Right-Angle (RA)** configuration. * **Common Specs:** * **Impedance:** 50 Ohms. * **Frequency Range:** DC to 12.4 GHz (depending on connector type). --- ### 3. Technical Identification Table If you are looking for this part in a database (like Digi-Key or Mouser), here is how it is categorized: | Category | Typical Part Number Example | Common Application | | :--- | :--- | :--- | | **Passive Components** | RC0603-415-R2 | Voltage dividers, Current limiting | | **RF Connectors** | 415-0003-R2 | GPS antennas, WiFi modules, Laboratory testing | | **Industrial Relays** | 415-R2-Series | Control panels, Automation | ### 4. Code Block Example: Resistance Calculation If "415" is the EIA-96 marking on a precision resistor, the calculation is handled via lookup tables. ```python # Example logic for standard resistor marking def decode_resistor(code): if code == "415": return "415 Ohms (Direct Reading)" else: return "Requires EIA-96 Table Lookup" print(decode_resistor("415")) ``` --- **Summary:** To identify the exact part, check the **physical shape**. If it is a tiny black rectangle, it is a **resistor**. If it is a gold/silver metal plug, it is an **RF Connector**.
