The **AM20-R068K-RC** is a specific type of electronic component known as a **Molded Inductor** (specifically a RF Choke). It belongs to the AM20 series, typically manufactured by companies like Allied Components International. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Part Number Breakdown The alphanumeric code provides specific details about the component's values and tolerances: | Segment | Meaning | Description | | :--- | :--- | :--- | | **AM20** | Series Name | Indicates the physical size and package type (Molded Inductor). | | **R068** | Inductance Value | Represents **0.068 µH** (Microhenries). | | **K** | Tolerance | **±10%** deviation from the nominal inductance. | | **RC** | Compliance | Indicates **RoHS Compliant** (Lead-free). | --- ### 2. Technical Specifications These are the typical electrical characteristics for this specific part: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.068 µH | | **Q Factor (Min)** | 40 (at test frequency) | | **Self-Resonant Frequency (SRF)** | ~450 MHz (Minimum) | | **DC Resistance (DCR) Max** | ~0.10 Ohms | | **Rated Current (Idc)** | ~1000 mA (1.0 Amp) | | **Operating Temperature** | -55°C to +125°C | --- ### 3. Physical Construction * **Package Type:** Axial Leaded (Through-hole). * **Encapsulation:** Molded epoxy resin. This provides excellent environmental protection, moisture resistance, and mechanical strength. * **Core Material:** Typically Phenolic or Ferrite depending on the specific frequency range (Phenolic is common for very low inductance RF chokes). * **Color Coding:** Often marked with color bands (similar to resistors) to denote the value in microhenries. --- ### 4. Common Applications The AM20-R068K-RC is designed primarily for High-Frequency (RF) applications where it acts as a filter or a "choke." * **RF Coupling/Decoupling:** Blocking high-frequency noise while allowing DC current to pass. * **Filter Networks:** Used in LC (Inductor-Capacitor) circuits for signal processing. * **Telecommunications:** Used in radio transmitters, receivers, and cellular infrastructure. * **EMI Suppression:** Reducing electromagnetic interference in sensitive electronic circuits. ---
