The **AISC-1008-R68** is a specific type of **SMD (Surface Mount Device) Power Inductor**. These components are essential in modern electronics for managing power, filtering noise, and storing energy in magnetic fields. --- ## 1. Technical Specifications The nomenclature of this part reveals its physical and electrical characteristics: | Parameter | Value / Description | | :--- | :--- | | **Series** | AISC (Abrasive/Shielded Chip Inductor) | | **Footprint (Size)** | 1008 (2.5mm x 2.0mm) | | **Inductance** | 0.68 µH (Represented by "R68") | | **Tolerance** | Typically ±5%, ±10%, or ±20% (depending on the suffix) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Core Material** | Usually Ceramic or Ferrite | --- ## 2. Key Electronic Properties ### A. Inductance (0.68 µH) The "R" in R68 acts as a decimal point. This value determines the inductor's ability to oppose changes in electric current. At 0.68 µH, this is considered a **low-inductance** component, typically used for high-frequency applications. ### B. Quality Factor (Q-Factor) These inductors are designed for a high Q-factor, meaning they have low relative loss. This makes them efficient in resonant circuits and high-frequency communication modules. ### C. Self-Resonant Frequency (SRF) Because of the small 1008 form factor, these parts usually have a high SRF. Above this frequency, the component stops acting like an inductor and starts acting like a capacitor due to parasitic effects. ### D. DC Resistance (DCR) The 1008 series is optimized for low DCR. A lower resistance ensures that less energy is wasted as heat, which is critical for battery-powered devices. --- ## 3. Typical Applications The AISC-1008-R68 is commonly found in the following electronic environments: 1. **Mobile Devices:** Cell phones and tablets for power management units (PMIC). 2. **RF Circuits:** Used in impedance matching and decoupling for Bluetooth or Wi-Fi modules. 3. **DC-DC Converters:** Acts as an energy storage element in small-scale switching regulators. 4. **Signal Filtering:** Removing high-frequency noise from data lines. --- ## 4. Construction Detail The component generally consists of a wire-wound ceramic or ferrite body. The "1008" package is preferred in automated assembly because its flat top allows for easy "pick-and-place" by vacuum nozzles. ```yaml Component_Structure: Body: Ceramic or Ferrite core Terminations: Gold or Tin plated (Lead-Free/RoHS compliant) Winding: Copper wire Protection: Epoxy coating or molded case ```
