## Technical Overview of CTMC1008F-R015J The **CTMC1008F-R015J** is a surface-mount (SMD) wire-wound ceramic core chip inductor. It is designed for high-frequency applications where high stability and high Q-factors are required. ### 1. Part Number Breakdown Understanding the nomenclature helps identify its specific characteristics: | Component Segment | Value | Description | | :--- | :--- | :--- | | **Series** | CTMC | Wire-wound Chip Inductor (Molded) | | **Size** | 1008 | Case size: 0.10 x 0.08 inches (2.5 x 2.0 mm) | | **Material** | F | Ferrite/Ceramic Core variant | | **Inductance** | R015 | 0.015 µH (or 15 nH) | | **Tolerance** | J | ±5% | --- ### 2. Key Electrical Specifications Below are the typical technical parameters for this specific component: | Parameter | Value | | :--- | :--- | | **Inductance** | 15 nH | | **Tolerance** | ±5% | | **Quality Factor (Q min)** | 25 - 50 (at specific frequencies) | | **SRF (Self Resonant Frequency)** | >2000 MHz (Typical) | | **DCR (DC Resistance)** | ~0.10 - 0.20 Ohms (Max) | | **Rated Current** | ~500mA - 700mA | | **Operating Temperature** | -40°C to +125°C | --- ### 3. Core Construction & Material * **Ceramic/Molded Body:** The "F" designation often refers to a molded construction that provides excellent mechanical strength and resistance to environmental factors (moisture, heat). * **Wire-Wound Technology:** Unlike multilayer inductors, wire-wound inductors offer much lower DC resistance (DCR) and significantly higher current handling capabilities. --- ### 4. Common Applications Due to its low inductance value (15nH) and high SRF, this part is commonly used in: * **RF Circuits:** Matching networks, filters, and oscillators. * **Wireless Communication:** WiFi modules, Bluetooth devices, and cellular infrastructure. * **High-Speed Signal Lines:** For EMI suppression and decoupling in high-frequency data paths. --- ### 5. Footprint (Dimensions) The **1008** package is a standard EIA size: * **Length:** 2.5 mm * **Width:** 2.0 mm * **Height:** Typically 1.6 mm to 1.8 mm (depending on specific manufacturer molding).
