The **IM-0140-P** is a specific electronic component, typically identified as a **Radial Lead Inductor** (specifically a shielded or unshielded molded inductor) manufactured by companies like Vishay Dale. These parts are designed for high-reliability applications and decoupling in electronic circuits. --- ### 1. Technical Specifications The following table outlines the typical electrical and physical characteristics of the IM-0140-P series: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Fixed Inductor (Molded) | | **Inductance Range** | Variable (Specific to the dash number) | | **Mounting Type** | Through-Hole (Radial Leads) | | **Core Material** | Phenolic, Powdered Iron, or Ferrite | | **Operating Temperature** | -55°C to +105°C (Standard) | | **Lead Finish** | Tin/Lead or Matte Tin (RoHS compliant options) | --- ### 2. Key Features * **Molded Construction:** The internal coil is protected by a rugged epoxy or phenolic molding, providing excellent moisture resistance and mechanical strength. * **Flame Retardant:** The coating is typically flame retardant, meeting UL standards for safety in power supplies. * **Small Footprint:** Designed for high-density printed circuit board (PCB) layouts where vertical space is available but horizontal space is limited. * **High Q Factor:** Optimized for high-frequency performance and low signal loss. --- ### 3. Common Applications The IM-0140-P is generally used in circuits requiring noise filtration or energy storage: 1. **RF Circuits:** Used for tuning and frequency selection. 2. **Power Supplies:** Acts as a filter to smooth out ripple voltage and block high-frequency noise (EMI/RFI). 3. **Telecommunications:** Signal decoupling and impedance matching. 4. **Decoupling:** Placed near integrated circuits (ICs) to prevent noise from entering the power rail. --- ### 4. Part Number Breakdown While the suffix `-P` often denotes **Phenolic core** or a specific **Packaging** (like bulk or taped), the general structure follows this logic: * **IM:** Inductor Molded. * **0140:** The physical size/frame dimensions. * **P:** Core material or specialized testing indicator. ---
