The **WSP-1DA-R** is a specialized electronic component, typically categorized as a **Surface Mount Device (SMD) Power Inductor** or a specific **Pressure Sensor** component depending on the manufacturer (most commonly associated with the **WSP series** of miniature inductive components). Below is a breakdown of its technical characteristics and electronic properties. --- ### 1. Technical Specifications The "1DA-R" suffix often denotes specific tolerance and packaging ratings. Here are the general specifications for this class of component: | Feature | Description | | :--- | :--- | | **Component Type** | Power Inductor / Wire-wound Chip Inductor | | **Inductance Range** | Typically 1.0 µH (Standard for 1D code) | | **Tolerance** | ±20% (Standard for "M" or "A" class) | | **Operating Temp** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Shielding** | Magnetically Shielded (prevents EMI) | --- ### 2. Key Electronic Functions The WSP-1DA-R serves several critical roles within a PCB assembly: 1. **Energy Storage:** It stores energy in a magnetic field when electric current flows through it, essential for DC-DC converter circuits. 2. **Filtering:** It acts as a low-pass filter, allowing DC to pass while blocking high-frequency noise (EMI suppression). 3. **Voltage Regulation:** In "Buck" or "Boost" converters, it helps maintain a steady output voltage despite fluctuations in input or load. --- ### 3. Physical Construction The part is engineered for high-density layouts where space is limited. * **Core Material:** Usually Ferrite or Metal Alloy to provide high saturation current. * **Terminations:** RoHS-compliant tin (Sn) plating over copper, designed for reflow soldering. * **Packaging:** Supplied in Tape & Reel (**-R** suffix) for automated "Pick and Place" assembly machines. --- ### 4. Typical Applications The WSP-1DA-R is commonly found in the following electronic devices: * **Smartphones & Tablets:** For power management ICs (PMIC). * **Wearables:** Due to its miniature footprint. * **SSD Drives:** Filtering power rails for high-speed data processing. * **IoT Modules:** Providing stable power for RF transmission.
