The **S506-32-R** is a specific electronic component belonging to the **S506 series** of fuses. It is a time-delay (slow-blow), high-breaking capacity glass tube fuse manufactured by Eaton (formerly Bussmann). --- ### ## Technical Specifications The following table outlines the primary electrical and physical characteristics of the S506-32-R: | Parameter | Specification | | :--- | :--- | | **Part Number** | S506-32-R | | **Series** | S506 (Time-delay, high breaking capacity) | | **Current Rating** | 32 mA (0.032 Amps) | | **Voltage Rating** | 250 Vac | | **Fuse Type** | Glass Tube (5mm x 20mm) | | **Characteristic** | Time-Delay / Slow-Blow (T) | | **Breaking Capacity** | 35A at 250Vac | | **Termination Style** | Cartridge (Ferrule) | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ### ### Key Features 1. **Time-Delay (Slow-Blow):** Unlike fast-acting fuses, the S506-32-R is designed to withstand temporary surges or "inrush currents" without blowing. This is crucial for circuits containing capacitors or inductive loads that draw high current for a fraction of a second upon startup. 2. **Glass Body:** The transparent glass construction allows for easy visual inspection to determine if the internal filament has melted (blown). 3. **Low Amperage:** At 32mA, this is a highly sensitive fuse designed to protect delicate low-power electronic circuitry. 4. **Standard Dimensions:** The 5x20mm form factor is a global standard, making it compatible with a wide variety of fuse holders, clips, and blocks. --- ### ### Typical Applications Because of its low current rating and slow-blow characteristic, this fuse is commonly found in: * **Medical Equipment:** Protecting sensitive diagnostic sensors. * **Industrial Controls:** Protecting PLC inputs or small control transformers. * **Power Supplies:** Secondary stage protection for low-voltage rails. * **Instrumentation:** Scientific and laboratory measurement devices. --- ### ### Deciphering the Part Number * **S506:** The series designation (5x20mm, Time-delay). * **32:** The current rating in milliamperes (mA). * **-R:** Indicates compliance with RoHS (Restriction of Hazardous Substances) standards.
