The **1210F-R82** is a specific part number for a surface-mount electronic component, typically representing a **fixed inductor**. Below is a detailed breakdown of its specifications based on standard electronic naming conventions (likely from manufacturers like Fastron, Bourns, or Gowanda). --- ## 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Fixed Inductor | Passive component that stores energy in a magnetic field. | | **Package Size** | 1210 (Imperial) | Dimensions: approx. 3.2mm x 2.5mm. | | **Inductance Value** | 0.82 µH | The "R" acts as a decimal point (R82 = 0.82). | | **Tolerance** | ±1% (F) | The "F" suffix denotes high precision. | | **Mounting Type** | SMT / SMD | Designed for Surface Mount Technology. | | **Core Material** | Ferrite or Phenolic | Usually wire-wound on a ceramic or ferrite core. | --- ## 2. Part Number Breakdown Understanding the alphanumeric code helps in identifying variations of the component: 1. **1210**: Refers to the **Case Size**. In the metric system, this is equivalent to **3225**. 2. **F**: Refers to the **Tolerance**. * F = ±1% * J = ±5% * K = ±10% 3. **R82**: Refers to the **Inductance Value** in Microhenries (µH). * The "R" represents the decimal point. 0.82 µH is a relatively low inductance, often used for high-frequency applications. --- ## 3. Applications and Usage These small-form-factor inductors are commonly found in the following circuits: * **RF Tuning:** Used in radio frequency circuits for signal filtering. * **DC-DC Converters:** Acts as an energy storage element in power management modules. * **Decoupling:** Used to filter out high-frequency noise from power supply lines. * **Consumer Electronics:** Found in smartphones, tablets, and wearable devices due to the compact 1210 footprint. --- ## 4.
