The term **0114-R** typically refers to a specific part number or suffix used by electronic component manufacturers (such as **API Delevan**, **Gowanda**, or various resistor manufacturers) to denote specifications like inductance, resistance, or lead-free compliance. Below is an analysis of what "0114-R" generally represents in the electronics industry. --- ### 1. Common Identifications Depending on the manufacturer, 0114-R is most commonly associated with **Inductors** or **Fixed Resistors**. | Component Type | Likely Manufacturer | Meaning of "R" | | :--- | :--- | :--- | | **Inductor** | API Delevan / Gowanda | Denotes RoHS (Lead-Free) Compliance | | **Resistor** | Various | Can denote Ohms (e.g., 0.114 $\Omega$) or RoHS | | **Fuse** | Littelfuse / Eaton | Standard series designation | --- ### 2. Breakdown of the API Delevan Series (Inductors) In many industrial contexts, "0114" refers to a series of **Molded Unshielded RF Coils**. #### Technical Specifications: * **Type:** Thru-hole RF Inductor. * **Operating Temperature:** -55°C to +125°C. * **Core Material:** Iron or Ferrite (depending on the specific value). * **The "-R" Suffix:** This is the most critical part of the modern part number. It indicates that the part is **RoHS Compliant** (Lead-Free). Parts without the "-R" may contain lead in the solder or finish. #### Example Table: 0114 Series Characteristics | Parameter | Value Range | | :--- | :--- | | Inductance Range | 0.10 $\mu$H to 1000 $\mu$H | | Tolerance | $\pm$10% (Standard) | | Finish | Gold plated or Tin/Silver | --- ### 3. Usage in Circuit Design If you are replacing a 0114-R component on a PCB, consider these factors: 1. **RoHS Compatibility:** If your assembly process requires lead-free materials, you must use the "-R" version. 2. **Frequency Response:** As an RF inductor, it is designed for high-frequency filtering and decoupling. Substituting it with a standard power inductor may cause circuit instability. 3. **Physical Footprint:** These are typically small, cylindrical molded parts with axial leads. --- ### 4.
