The term **758-R** generally refers to a specific series of high-performance surface-mount components, most commonly associated with **Inductors** or **Resistors** produced by manufacturers like Vishay or Bourns. Below is a breakdown of the electronic characteristics typically associated with these parts. --- ### 1. Typical Component Identification While part numbers can vary by manufacturer, "758-R" is most frequently found in the context of **Power Inductors** or **Precision Chip Resistors**. | Feature | Specification (General) | | :--- | :--- | | **Component Type** | SMT (Surface Mount Technology) | | **Common Application** | Power management, DC-DC converters, Signal filtering | | **Mounting Style** | SMD / SMT | | **RoHS Status** | Usually Compliant (indicated by "R") | --- ### 2. Technical Specifications Depending on the specific manufacturer (e.g., if it is a 758 series power inductor), the following technical parameters apply: #### A. Electrical Properties * **Inductance Range:** Usually ranges from $1.0\mu H$ to $1000\mu H$. * **Current Rating:** Designed for high-current applications, often handling between 1A and 10A depending on the package size. * **Tolerance:** Standard tolerances are usually $\pm 10\%$ or $\pm 20\%$. #### B. Physical Construction * **Shielding:** Many 758-R inductors are magnetically shielded to reduce Electromagnetic Interference (EMI). * **Core Material:** Ferrite core for high efficiency and low core loss. --- ### 3. Decoding the Part Number Usually, the suffix **-R** in electronic components carries a specific meaning: 1. **RoHS Compliant:** The "R" often signifies that the part meets environmental standards for lead-free construction. 2. **Tape and Reel:** In some catalogs, "R" indicates the packaging method (Reel) for automated pick-and-place machines. 3. **Resistance/Reverse:** In diodes or resistors, it can indicate a specific orientation or a decimal point ($7.58 \Omega$). --- ### 4. Common Applications These parts are typically integrated into: * **Power Supplies:** Used as filter elements in switching regulators. * **Consumer Electronics:** Found on motherboards, laptops, and tablets. * **Automotive:** High-reliability versions are used in LED lighting drivers and infotainment systems. ---
