The term **1114-R** typically refers to specific electronic components, most commonly associated with **inductors** or **high-power resistors**. Below is an explanation of the two most frequent interpretations of this part number in the electronics industry. --- ### 1. Power Inductors (Shielded/Unshielded) In many manufacturer catalogs (such as Bourns or J.W. Miller), "1114" refers to the physical dimensions of a surface-mount or through-hole inductor. The **-R** suffix usually denotes **RoHS Compliance** (lead-free). | Feature | Specification | | :--- | :--- | | **Package Size** | Approx. 11mm x 14mm | | **Mounting Type** | Through-hole or SMD (depends on series) | | **Core Material** | Ferrite | | **Suffix (-R)** | RoHS Compliant / Lead-Free | | **Applications** | DC/DC converters, Power supplies, EMI filtering | ### 2. High-Power Wirewound Resistors Certain legacy manufacturers use the 1114-R designation for heavy-duty power resistors used in industrial braking or load testing. * **Construction:** Wire wound around a ceramic core, often coated in vitreous enamel or silicone. * **Resistance Value:** If "R" is placed within numbers (e.g., 11R4), it represents a decimal point (11.4 Ohms). If it is a suffix, it denotes RoHS. * **Heat Dissipation:** These parts are designed to handle high temperatures and significant wattage. --- ### Technical Identification Guide If you are looking at a specific component, check these physical markers to identify it correctly: | Physical Appearance | Likely Component | | :--- | :--- | | **Small, square/round, wire coil inside** | Power Inductor | | **Long, cylindrical, ceramic body** | Power Resistor | | **3-pin plastic package (TO-220 style)** | Voltage Regulator or Transistor (Specific custom batch) | ### Sample Code for Component Database Lookup If you are using a Python script to filter these parts in a Bill of Materials (BOM), you might use a pattern like this: ```python import re components = ["1114-R-101K", "1114-R-220M", "RES-500W-1114"] # Regex to find parts starting with 1114 and ending with RoHS suffix pattern = r"1114-R.*" found_parts = [p for p in components if re.match(pattern, p)] print(f"Identified Parts: {found_parts}") ``` ---
