The **CT1008LSCF-R33K** is a high-performance surface-mount (SMD) wire-wound inductor. It belongs to the 1008 series, which is a standard industry size for small-signal and RF applications. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Parameter | Value | Description | | :--- | :--- | :--- | | **Inductance** | 0.33 µH (330 nH) | The energy storage capacity of the part. | | **Tolerance** | ±10% (K) | The allowable variance from the nominal inductance. | | **Package Size** | 1008 (2520 Metric) | Dimensions: approx. 2.5mm x 2.0mm. | | **Construction** | Wire-wound Ceramic | Ceramic core for high-frequency stability. | | **SRF (Min)** | 600 MHz | Self-Resonant Frequency; the limit of inductive behavior. | | **DCR (Max)** | 0.54 Ohms | DC Resistance; lower values reduce heat dissipation. | | **Rated Current** | 450 mA | Maximum current before overheating or saturation. | --- ### 2. Key Component Features * **Ceramic Core:** Unlike ferrite cores, ceramic cores provide excellent thermal stability and a high "Q" factor at high frequencies, though they offer lower inductance values. * **High Q Factor:** This part is designed for high-frequency applications where low loss (high Quality factor) is critical for signal integrity. * **Wire-Wound Technology:** Offers much higher current handling and lower DC resistance compared to multilayer chips of the same size. --- ### 3. Common Applications Due to its 330nH inductance and high SRF, this component is typically found in: 1. **RF Circuits:** Used in matching networks and filters for wireless communication. 2. **Impedance Matching:** Often placed in the antenna path of Bluetooth, Wi-Fi, or cellular modules. 3. **Decoupling:** Filtering out high-frequency noise from power supply lines in sensitive analog circuits. --- ### 4. Part Number Breakdown Here is how the manufacturer (Central Technologies) defines the code: * **CT**: Central Technologies (Manufacturer). * **1008**: Case size (0.10 x 0.08 inches). * **LS**: Series identifier (Low Profile/Standard). * **CF**: Ceramic Core / Lead-Free. * **R33**: Inductance value (R = Decimal, so 0.33 µH). * **K**: Tolerance (±10%).
