• Lead Material: Tin-plated copper

Detailed Pin Configuration

The VDRS07H420TME typically has two leads for through-hole mounting. The pin configuration may vary slightly based on the manufacturer, but generally follows a standard layout with one lead connected to each end of the varistor element.

Functional Features

• Overvoltage Protection: Provides protection against transient voltage spikes.
• Fast Response Time: Rapidly clamps excessive voltage to protect downstream circuitry.
• Reliable Operation: Designed for consistent performance over a wide range of operating conditions.

Advantages

• Effective protection against voltage surges
• Wide operating temperature range
• Compact and easy to integrate into circuit designs

Disadvantages

• Limited lifespan under repeated high-energy surge events
• Requires careful consideration of clamping voltage for specific applications

Working Principles

VDRS07H420TME operates based on the principle of voltage-dependent resistance. When the voltage across the varistor exceeds its threshold, it rapidly decreases its resistance, diverting excess current away from sensitive components.

Detailed Application Field Plans

• Power Supplies: Protects sensitive electronics from power line transients.
• Telecommunications Equipment: Safeguards communication devices from lightning-induced surges.
• Industrial Control Systems: Shields control circuitry from voltage spikes in industrial environments.

Detailed and Complete Alternative Models

• VDRS05H320TME: Lower voltage rating for less demanding applications.
• VDRS10H500TME: Higher voltage rating for more robust protection.

This comprehensive range of alternative models allows for tailored selection based on specific application requirements.
