The **2087-100SM-RPLF** is a specialized high-voltage Gas Discharge Tube (GDT) manufactured by **Bourns Inc.** It is designed primarily for circuit protection against transient voltage surges, such as those caused by lightning or industrial switching. --- ### ## Technical Specifications The following table outlines the key electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Bourns Inc. | | **Series** | 2087 (High Voltage GDT) | | **DC Sparkover Voltage** | 1000V (±20%) | | **Number of Poles** | 2-Pole | | **Mounting Type** | Surface Mount (SMD) | | **Impulse Discharge Current** | 5 kA (8/20 μs waveform) | | **Insulation Resistance** | > 1 GΩ | | **Capacitance** | < 1.0 pF | | **RoHS Status** | RoHS Compliant (Lead-Free) | --- ### ### Key Features and Functions 1. **Overvoltage Protection:** The device acts as a "crowbar." When the voltage exceeds 1000V, the gas inside ionizes, creating a low-impedance path to ground to shunt the excess energy away from sensitive components. 2. **Low Capacitance:** With a capacitance of less than 1 pF, this part is ideal for high-speed data lines or RF applications where signal integrity must be maintained without distortion. 3. **Compact SMD Design:** The "SM" in the part number indicates a surface-mount package, making it suitable for modern automated PCB assembly. 4. **Robustness:** Despite its small size, it can handle impulse currents up to 5,000 Amperes (5kA). --- ### ### Typical Applications * **Power Supplies:** Protecting the AC or DC input stages from line surges. * **Telecommunications:** Guarding sensitive data ports against lightning strikes. * **Industrial Equipment:** Used in motor controllers or PLCs where high-voltage transients are common. * **Medical Electronics:** Providing a safety barrier against high-voltage spikes. --- ### ### Part Number Breakdown * **2087:** Series designation (High Voltage Mini 2-Pole GDT). * **100:** Represents the voltage (1000V). * **SM:** Surface Mount package style. * **RP:** Reel Pack (packaging format). * **LF:** Lead-Free (RoHS compliant).
