The part number **06-800-R** is most commonly associated with a specific series of high-performance **fuses** manufactured by **Bel Fuse Inc.** --- ### 1. Product Overview The 06-800-R belongs to the **MRT Series** (Micro Radial Time-Lag). These are subminiature fuses designed for space-constrained circuit boards that require "slow-blow" characteristics to handle initial power surges without tripping. ### 2. Technical Specifications Below are the primary technical parameters for this electronic component: | Feature | Specification | | :--- | :--- | | **Component Type** | Radial Lead Micro Fuse | | **Current Rating** | 800mA (indicated by "800") | | **Voltage Rating (AC)** | 250V | | **Characteristic** | Time-Lag (T) / Slow Blow | | **Package / Case** | Radial (Cylindrical Plastic Body) | | **Lead Spacing** | 5.08 mm (Standard) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 3. Key Characteristics * **Time-Delay (Slow-Blow):** Unlike "Fast-Acting" fuses, the 06-800-R can withstand a temporary overcurrent (such as an inrush current when a device is first turned on) for a few milliseconds before blowing. * **Physical Footprint:** It features a small, round plastic housing with two pins extending from the bottom, making it ideal for high-density PCB mounting. * **Safety Approvals:** Typically carries certifications from UL (Underwriters Laboratories), VDE, and SEMKO, ensuring it meets international safety standards for circuit protection. ### 4. Common Applications This part is typically found in: 1. **Power Supplies:** Protecting the primary side of AC/DC adapters. 2. **Consumer Electronics:** Used in chargers, LED drivers, and small appliances. 3. **Industrial Equipment:** Protecting low-power control circuits. 4. **Telecom:** Protection for networking hardware. --- ### 5. Part Number Breakdown The part number is structured to define its specific traits: | Segment | Meaning | | :--- | :--- | | **06** | Series Identifier (MRT Radial Fuse) | | **-800-** | Current rating (800 Milliamperes) | | **R** | RoHS Compliant / Lead-Free | ---
