The **AL05-R10-KA** is a specific part number for a passive electronic component, specifically an **axial leaded inductor**. These components are used to filter signals, store energy in magnetic fields, or block high-frequency AC noise while allowing DC to pass. ### Component Breakdown The part number can be decoded as follows: | Code | Segment | Description | | :--- | :--- | :--- | | **AL** | Series | Axial Leaded Inductor (Standard Type) | | **05** | Physical Size | Typically refers to the body diameter (~5.0mm to 5.5mm) | | **R10** | Inductance Value | **0.10 µH** (R acts as a decimal point) | | **K** | Tolerance | **±10%** | | **A** | Packaging | **A**mmo Pack (Tape and Box) | --- ### Technical Specifications While exact specifications can vary slightly by manufacturer (such as Taiyo Yuden or Viking Tech), the standard parameters for an R10 axial inductor are generally: | Parameter | Typical Value | | :--- | :--- | | **Inductance** | 0.10 µH | | **Tolerance** | ±10% | | **Core Material** | Phenolic or Ferrite | | **Self-Resonant Frequency (SRF)** | Very High (>500 MHz) | | **DC Resistance (DCR)** | Very Low (<0.1 Ω) | | **Rated Current** | High (often >1000mA due to low inductance) | --- ### Key Applications 1. **RF Circuits:** Due to the low inductance value (0.10 µH), these are often used in high-frequency applications for impedance matching or signal decoupling. 2. **Noise Filtering:** Acting as a "choke" to prevent high-frequency electromagnetic interference (EMI) from entering or leaving a circuit. 3. **Decoupling:** Used in power supply lines to suppress switching noise. ### Physical Design The "Axial" designation means the leads come out of both ends of the cylindrical body, similar to a standard resistor. * **Body Coating:** Usually coated in epoxy resin for environmental protection. * **Color Coding:** Often uses a color-band system (similar to resistors) to indicate inductance value and tolerance. --- ### Comparison with Surface Mount (SMD) Unlike SMD inductors (e.g., 0805 or 1210 sizes), the AL05-R10-KA is a **Through-Hole Technology (THT)** component. It is preferred for: * Prototyping on breadboards. * Power electronics requiring high mechanical strength. * Legacy hardware repairs.
