## Component Overview: CT1008LSCF-R15K The **CT1008LSCF-R15K** is a specialized surface-mount (SMD) wire-wound chip inductor. It belongs to the **1008 series** (referring to its physical dimensions) and is designed for high-frequency applications where high Q-factors and stable inductance are required. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific characteristics of the component: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **CT** | Manufacturer Series | Central Technologies Inductor Series | | **1008** | Case Size | 0.10 x 0.08 inches (approx. 2.5 x 2.0 mm) | | **LS** | Type | Wire-wound, Ceramic core | | **CF** | Features | Low profile / Lead-Free (RoHS Compliant) | | **R15** | Inductance Value | **0.15 µH** (150 nH) | | **K** | Tolerance | **±10%** | --- ### 2. Technical Specifications The electrical performance is optimized for RF (Radio Frequency) circuits. | Parameter | Value | | :--- | :--- | | **Inductance** | 0.15 µH (150 nH) | | **Tolerance** | ±10% | | **Quality Factor (Q min)** | 28 @ 50 MHz | | **Self-Resonant Frequency (SRF)** | 920 MHz (Min) | | **DC Resistance (DCR max)** | 0.56 Ω | | **Rated DC Current (Idc)** | 570 mA | | **Operating Temperature** | -40°C to +125°C | --- ### 3. Key Electronic Characteristics #### A. Wire-Wound Construction Unlike multilayer inductors, this part uses a fine copper wire wound around a ceramic core. This results in: * **Higher Q-Factors:** Lower energy loss at high frequencies. * **Higher Current Handling:** Better thermal performance compared to thin-film alternatives. #### B. Ceramic Core The use of a ceramic (non-magnetic) core ensures that the inductance remains extremely stable across a wide range of temperatures and frequencies, as there is no magnetic saturation. #### C. Self-Resonant Frequency (SRF) With an SRF of 920 MHz, this inductor is effective for applications operating well into the VHF and UHF bands. Beyond this frequency, the component will behave capacitively rather than inductively. --- ### 4. Common Applications * **RF Transceivers:** Used in matching networks and filters for wireless communication. * **Oscillators:** Providing stable inductance for frequency generation. * **High-Speed Data Lines:** Used for EMI suppression or signal conditioning. * **Mobile Communication:** Integrated into GPS, Bluetooth, and Wi-Fi modules.
