The **FRL155-R82-KBQ** is a specific electronic component, typically categorized as a **fixed inductor** (often an axial leaded or molded type). Below is a breakdown of its technical specifications and physical characteristics. --- ### 1. Part Number Deciphering The part number follows a standard nomenclature used by manufacturers (often associated with brands like **FRL** or similar axial inductor series). | Segment | Meaning | Specification | | :--- | :--- | :--- | | **FRL155** | Series Model | Indicates the physical size and package type (Axial leaded). | | **R82** | Inductance Value | **0.82 µH** (Microhenries). "R" acts as the decimal point. | | **K** | Tolerance | **±10%** (Standard industrial tolerance). | | **B** | Packaging/Forming | Usually denotes Bulk packaging or a specific lead forming. | | **Q** | Qualification/Special | Often indicates Quality or Automotive grade (AEC-Q200) depending on the vendor. | --- ### 2. Technical Specifications Based on the standard 0.82 µH axial inductor profile, here are the estimated performance parameters: * **Inductance:** 0.82 µH * **Tolerance:** ±10% * **Core Material:** Ferrite (allows for high-frequency performance and low losses). * **DC Resistance (DCR):** Low (typically < 0.2 Ohms), allowing for efficient current flow. * **Rated Current (Idc):** Usually ranges between 500mA to 1.5A depending on the specific wire gauge used internally. * **Operating Temperature:** Typically -40°C to +105°C. --- ### 3. Physical Construction The "FRL155" series is generally an **Axial Leaded Inductor**. * **Coating:** Encapsulated in an epoxy resin or molded plastic for environmental protection. * **Color Coding:** Many versions use a four-band color code system (Grey, Red, Silver, Silver/Gold) to denote the 0.82 µH value and tolerance. * **Size:** Small footprint, designed for Through-Hole Technology (THT) mounting on PCBs. --- ### 4. Applications This component is used for filtering, decoupling, and energy storage in electronic circuits: 1. **Noise Suppression:** Used in power supplies to filter out high-frequency electromagnetic interference (EMI). 2. **Signal Conditioning:** Utilized in RF (Radio Frequency) circuits for tuning or impedance matching. 3. **Decoupling:** Placed near IC power pins to prevent noise from entering the chip.
