The **AL05-R10-KTQ** is a specific part number for a passive electronic component, specifically an **axial-leaded fixed inductor**. This component is commonly used for filtering, decoupling, and frequency selection in various electronic circuits. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Part Number Deciphering The part number follows a standard nomenclature used by manufacturers (like Aerodev or similar passive component specialists): | Segment | Meaning | Detail | | :--- | :--- | :--- | | **AL** | Series Type | Axial Leaded Inductor | | **05** | Case Size | Refers to the physical dimensions (approx. 4.0mm x 9.0mm) | | **R10** | Inductance Value | **0.10 µH** (R acts as the decimal point) | | **K** | Tolerance | **±10%** | | **T** | Packaging | Tape & Reel (T) or Ammo Pack | | **Q** | Compliance | Often denotes RoHS compliance or specific quality standard | --- ### 2. Key Technical Specifications Based on the standard parameters for the **AL05** series with an **R10** value: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.10 µH | | **Tolerance** | ±10% | | **Rated DC Current (Idc)** | ~800 mA to 1000 mA (1.0A) | | **DC Resistance (DCR)** | Max 0.10 – 0.15 Ω | | **Self-Resonant Frequency (SRF)** | > 400 MHz | | **Quality Factor (Q min)** | 35 - 50 (at specific test frequency) | | **Operating Temperature** | -25°C to +85°C | --- ### 3. Physical Construction * **Core Material:** Usually a phenolic or ferrite core depending on the inductance range. For low values like R10, it is often a non-magnetic or phenolic core to handle high frequencies. * **Coating:** Encapsulated in an epoxy resin or conformal coating (often green or blue) to provide environmental protection and insulation. * **Leads:** Tin-plated copper wires for through-hole soldering. --- ### 4. Typical Applications The AL05-R10-KTQ is designed for high-frequency applications where small inductance values are required: * **RF Circuits:** Impedance matching and signal tuning. * **EMI/RFI Filtering:** Suppressing high-frequency noise in power lines or signal paths. * **Decoupling:** Preventing unwanted signals from affecting sensitive stages of a circuit. * **Consumer Electronics:** Used in TVs, VCRs, and telecommunication equipment. --- ### 5. Color Coding (Standard 4-Band) If the inductor follows the standard EIA color code, a **0.10 µH ±10%** inductor would typically display: 1. **Band 1:** Brown (1) 2. **Band 2:** Black (0) 3. **Band 3:** Silver (Multiplier x0.01) 4. **Band 4:** Silver (Tolerance ±10%) ---
