The **AM20-R82K-RC** is an electronic component known as a **Molded Inductor** (specifically a radio frequency or RF choke). It is part of the AM20 series, typically manufactured by companies like Allied Components International. Below is a breakdown of its technical specifications and features. --- ### 1. Technical Specifications The part number itself follows a specific nomenclature that defines its electrical properties. | Parameter | Value | | :--- | :--- | | **Inductance** | 0.82 µH (Microhenries) | | **Tolerance** | ±10% (Indicated by the 'K' suffix) | | **Mounting Type** | Through-Hole (Axial Leads) | | **Body Construction** | Molded Phenolic or Epoxy Resin | | **Operating Temperature** | -55°C to +105°C | | **Compliance** | RoHS Compliant (Indicated by 'RC') | ### 2. Physical Characteristics The "AM20" designation typically refers to the physical size and power handling of the series. * **Form Factor:** Axial-leaded (resembling a resistor). * **Protection:** The "Molded" aspect means the internal coil is encased in a rigid plastic shell, providing excellent protection against moisture, shock, and vibration. * **Marking:** Usually identified by color bands (MIL-STD) or printed alphanumeric text. ### 3. Key Electronic Functions As an inductor, the AM20-R82K-RC serves several critical roles in a circuit: 1. **RF Choking:** It blocks high-frequency alternating current (AC) while allowing direct current (DC) to pass through. This is essential for preventing noise from entering power supply lines. 2. **Filtering:** Used in conjunction with capacitors to create Low-Pass filters. 3. **Impedance Matching:** Often found in RF (Radio Frequency) communication circuits to match the impedance between different stages of an amplifier or antenna. ### 4. Typical Applications * **Communication Equipment:** Radios, transceivers, and telecommunication base stations. * **Consumer Electronics:** Televisions and computer peripherals. * **Power Supplies:** Used in decoupling and EMI (Electromagnetic Interference) suppression. --- ### Code Representation: Part Number Breakdown If you were to parse this part number programmatically, it would look like this: ```json { "Series": "AM20", "Inductance_Value": "R82", "Inductance_Unit": "0.82 uH", "Tolerance_Code": "K", "Tolerance_Value": "10%", "Environmental": "RC", "Environmental_Meaning": "RoHS Compliant" } ```
