The **1008HT-R14T_L** is a high-performance **Wirewound Chip Inductor** part of the 1008HT series. These components are specifically designed for high-frequency applications where high Q (Quality) factors and tight tolerances are required. --- ### 1. Key Technical Specifications The following table summarizes the core electrical and physical characteristics of this specific component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 140 nH | | **Tolerance** | ±5% (indicated by 'J') or ±10% (indicated by 'K') | | **Quality Factor (Q min)** | 50 at 250 MHz | | **Self-Resonant Frequency (SRF)** | 1100 MHz (Minimum) | | **DC Resistance (DCR Max)** | 0.80 Ohms | | **Rated Current (Max)** | 450 mA | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 1008 (2.5 x 2.0 mm) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **1008**: Refers to the physical dimensions (0.10 x 0.08 inches). * **HT**: High Temperature / High Q Series. * **R14**: Represents the inductance value. `R` acts as a decimal point in microhenries (µH). Thus, $0.14 \mu H = 140 nH$. * **T**: Packaging style (usually Tape and Reel). * **L**: Often designates RoHS compliance or Lead-Free termination. --- ### 3. Construction and Materials The 1008HT series utilizes a **Ceramic Core** with a precision-wound copper wire. * **Non-Magnetic Core:** Unlike ferrite inductors, the ceramic core ensures that the inductance remains stable across a wide range of currents and temperatures without saturating. * **Flat Top:** Usually features a epoxy cap or flat top surface to allow for automated "pick and place" assembly. --- ### 4. Typical Applications Due to its high resonant frequency and low resistance, this part is commonly found in: 1. **RF Circuits:** Impedance matching in wireless transmitters. 2. **Filter Networks:** Band-pass and low-pass filters for telecommunications. 3. **VCOs:** Voltage Controlled Oscillators requiring stable frequency control. 4. **Mobile Infrastructure:** Base stations and signal repeaters. ---
