Part Number Breakdown Understanding the nomenclature helps identify the component's characteristics: | Code | Component Detail | Description | | :--- | :--- | :--- | | **CTC1F** | Series Name | Axial leaded, molded inductor series | | **R10** | Inductance Value | **0.10 µH** (R acts as a decimal point) | | **M** | Tolerance | **±20%** | --- ### 2. Technical Specifications Below are the typical electrical and physical parameters for the R10M variant: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.10 µH | | **Tolerance** | ±20% | | **Test Frequency** | 25.2 MHz | | **Quality Factor (Q Min)** | 40 | | **Self-Resonant Frequency (SRF Min)** | 680 MHz | | **DC Resistance (DCR Max)** | 0.08 Ohms | | **Rated DC Current (Imax)** | 1350 mA (1.35A) | | **Operating Temperature** | -55°C to +125°C | --- ### 3. Key Features * **Molded Construction:** The internal coil is encapsulated in a hard epoxy resin. This provides excellent environmental protection against moisture, vibration, and mechanical shock. * **Axial Leads:** Designed for through-hole mounting (THT) on printed circuit boards (PCBs). * **Color Coding:** These parts often feature color bands (similar to resistors) to indicate inductance value and tolerance. * **High Reliability:** Due to the molded design, they are often used in military or industrial applications where durability is required. --- ### 4. Common Applications The CTC1F-R10M is primarily used for high-frequency applications due to its low inductance and high SRF: 1. **RF Coupling/Decoupling:** Used to block high-frequency noise while allowing DC power to pass. 2. **Filters:** Part of LC circuits for signal filtering. 3. **EMI Suppression:** Reducing electromagnetic interference in power supplies or signal lines. 4. **Oscillators:** Serving as a frequency-determining component in RF circuits. ---
