The **1008HT-R15TGLD** is a specific electronic component, primarily classified as a **High-Temperature Chip Inductor**. It is manufactured by Coilcraft and belongs to the 1008HT series, known for its performance in extreme thermal environments. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electrical and mechanical properties: | Parameter | Value | | :--- | :--- | | **Inductance** | 150 nH (0.15 µH) | | **Tolerance** | ±2% (indicated by 'G') | | **Case Size** | 1008 (2.5 x 2.0 mm) | | **Core Material** | Ceramic | | **Termination** | Gold over Nickel over Molybdenum-Manganese | | **Max Operating Temp** | +200°C | --- ### 2. Breakdown of the Part Number To understand this component fully, we can decode the alphanumeric string: * **1008**: Refers to the physical dimensions (0.10 inches x 0.08 inches). * **HT**: High Temperature series (qualified for 200°C environments). * **R15**: Represents the inductance value. 'R' acts as a decimal point ($0.15 \mu H$ or $150 nH$). * **T**: Packaging type (usually Tape and Reel). * **G**: Tolerance code (G = ±2%). * **L**: Termination code (L = Gold plated). * **D**: Internal factory code/Packaging suffix. --- ### 3. Key Performance Features This part is engineered for specialized applications where standard commercial components would fail. 1. **Extreme Temperature Stability**: Unlike standard inductors rated for 125°C, the HT series uses materials that remain stable up to 200°C. 2. **Ceramic Core**: This provides high Q-factors (quality factors) and very high self-resonant frequencies (SRF), making it ideal for high-frequency RF applications. 3. **Gold Termination**: The gold finish is used to prevent oxidation and ensure reliable soldering or wire bonding in harsh environments, such as aerospace or down-hole drilling. --- ### 4. Common Applications * **Oil and Gas**: Down-hole instrumentation where ambient temperatures exceed 150°C. * **Aerospace**: Engine control units and sensors located near high-heat zones. * **Automotive**: Under-the-hood power electronics and exhaust sensors. * **RF Circuitry**: High-frequency filters and impedance matching where precision (2% tolerance) is required.
