The **CS160808-R68K** is a surface-mount electronic component, specifically a **Multilayer Chip Inductor**. It is widely used in high-frequency circuits for signal filtering and impedance matching. Below is a breakdown of its technical specifications and part number nomenclature. ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Multilayer Ceramic Chip Inductor | | **Inductance** | 0.68 µH (680 nH) | | **Tolerance** | ±10% (K) | | **Package Size (EIA)** | 0603 | | **Package Size (Metric)** | 1608 | | **DC Resistance (DCR)** | ~0.45 Ω (Max) | | **Rated Current** | ~100 mA | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Part Number Deciphering The part number follows a standard industry format: * **CS**: Product Series (Chip Inductor / Multilayer). * **1608**: Dimensions in millimeters. $1.6 \text{mm (Length)} \times 0.8 \text{mm (Width)}$. This corresponds to the **0603** inch size. * **08**: Thickness indicator (typically 0.8 mm). * **R68**: Inductance value. The "R" acts as a decimal point. $R68 = 0.68 \mu H$. * **K**: Tolerance code. $K = \pm 10\%$. --- ### 3. Key Applications Because this is a multilayer ceramic inductor (rather than wire-wound), it is optimized for low-power, high-density applications: 1. **RF Circuits:** Used in impedance matching and resonance circuits for Bluetooth, Wi-Fi, and cellular modules. 2. **Signal Conditioning:** Filtering high-frequency noise in communication lines. 3. **EMI Suppression:** Reducing electromagnetic interference in mobile devices and consumer electronics. --- ### 4. Comparison: Ceramic vs. Ferrite Core While the CS160808 series is often ceramic-based for high-frequency performance, some variations use ferrite cores for higher inductance values. ```yaml Comparison_Attribute: Ceramic_Core: "High Q factor, stable at high frequencies, lower inductance." Ferrite_Core: "Higher inductance, higher DCR, better for power filtering." CS160808-R68K: "Mid-range inductance suitable for RF filtering." ``` ---
