The **RL0809-152-R** is a specific electronic component belonging to the **Radial Leaded Inductor** family, typically manufactured by companies like Bourns or other specialized magnetic component suppliers. Below is a detailed breakdown of its specifications and characteristics. --- ### 1. Part Number Breakdown Understanding the alphanumeric code helps identify the physical and electrical properties: | Segment | Meaning | Details | | :--- | :--- | :--- | | **RL0809** | Series/Size | Radial Lead Inductor, dimensions approx. 8mm (diameter) x 9mm (height). | | **152** | Inductance Code | The first two digits are significant; the third is the multiplier ($15 \times 10^2$). | | **R** | RoHS Compliant | Indicates the part meets lead-free environmental standards. | --- ### 2. Key Electrical Specifications Based on standard datasheets for this series, here are the technical parameters for the **152** variant: | Parameter | Value | | :--- | :--- | | **Inductance** | $1500 \mu H$ (1.5 mH) | | **Tolerance** | Typically $\pm 10\%$ (K) | | **Test Frequency** | Usually measured at 1 kHz or 10 kHz | | **DCR (DC Resistance)** | Relatively high due to the fine wire needed for 1.5mH (approx. 2.0 - 5.0 $\Omega$) | | **Rated Current (I-dc)** | Low current, typically in the range of $50mA$ to $150mA$ | --- ### 3. Physical Characteristics * **Form Factor:** Radial leaded (two wires protruding from the bottom). * **Coating:** Usually encapsulated in a shrink-wrap sleeve or epoxy resin for environmental protection and insulation. * **Core Material:** Ferrite core, which allows for high inductance in a small volume. * **Mounting Type:** Through-hole (THT) on a Printed Circuit Board (PCB). --- ### 4. Common Applications Due to its high inductance and relatively low current rating, the RL0809-152-R is commonly used for: * **DC/DC Converters:** As a storage element in low-power power supplies. * **EMI/RFI Filtering:** To block high-frequency noise in power lines. * **Signal Processing:** Used in audio filters or timing circuits. * **Decoupling:** Preventing noise from spreading between different stages of a circuit. --- ### 5. Equivalent Replacement Example If you are looking for an alternative, ensure the footprint (8x9mm) and the DC resistance (DCR) match. ```yaml Alternative_Search_Criteria: - Type: Radial Fixed Inductor - Inductance: 1.5mH - Lead_Spacing: 5.0mm (standard for 0809 size) - Current_Rating: Must meet or exceed original circuit requirements ```
