The S14KV561E2 is a varistor from EPCOS (TDK), designed to protect electronic circuits from voltage surges and transient events. Varistors, or Voltage Dependent Resistors, exhibit a high resistance at normal operating voltages and a low resistance when subjected to high voltage surges. This allows them to effectively clamp voltage spikes and protect sensitive components.

Applications:

• Power supplies: Protection against voltage surges from the mains.
• Telecommunication equipment: Surge protection for communication lines.
• Industrial electronics: Protecting sensitive control circuits from voltage transients.
• Consumer electronics: Safeguarding devices like TVs, refrigerators, and washing machines.
• LED lighting: Protecting LED drivers from voltage spikes.

Features:

• High surge current capability: Designed to withstand high energy surges.
• Fast response time: Clamps voltage surges almost instantaneously.
• Wide operating voltage range: Suitable for various applications.
• RoHS compliant: Environmentally friendly, free from hazardous substances.
• Compact size: Easy to integrate into various circuit designs.

Benefits:

• Enhanced circuit protection: Prevents damage to sensitive electronic components.
• Increased product reliability: Reduces the risk of failures due to voltage surges.
• Improved safety: Protects users from electrical hazards.
• Extended equipment lifespan: Minimizes the impact of voltage transients on electronic devices.
• Cost-effective solution: Provides reliable protection at a reasonable cost.

Technical Specifications:

The S14KV561E2 has a varistor voltage of 560V. The disc diameter is approximately 14mm. It can withstand surge currents up to a specified level (consult the datasheet for exact values). The clamping voltage is also a critical parameter; refer to the datasheet for the specific clamping voltage levels at different surge current levels. It is constructed using a metal oxide ceramic material, providing robust performance and long-term stability. The operating temperature range is typically from -40°C to +85°C. This varistor is designed for through-hole mounting.
