The S05K350E2 is a varistor manufactured by EPCOS (TDK). It is designed to protect electronic circuits from transient overvoltage conditions. The 'E2' likely refers to a specific lead configuration or packaging variation. As a voltage-dependent resistor, its resistance decreases significantly when the voltage exceeds a certain threshold, thus diverting excess current away from sensitive components.

Applications

• Power supplies and adapters
• Consumer electronics (TVs, audio equipment)
• Industrial control systems
• Lighting systems
• Telecommunication equipment

Features

• Compact 5mm disk size
• High surge current handling capability
• Fast response time to voltage transients
• UL, CSA, and VDE approvals
• RoHS compliant

Benefits

• Provides reliable overvoltage protection
• Protects downstream electronic components from damage
• Improves the reliability and lifespan of electronic devices
• Reduces equipment downtime and repair costs

Additional Details

The S05K350E2 has a maximum continuous operating voltage of 350V AC and 460V DC. The typical varistor voltage at 1mA is around 560V. The surge current capability depends on the specific surge waveform and number of pulses. Refer to the datasheet for detailed specifications. The operating temperature range is typically -40°C to +85°C. The clamping voltage is a crucial parameter as it indicates the voltage level to which the protected circuit will be exposed during a surge event. Proper selection of the varistor based on the circuit's voltage requirements is essential for optimal protection. The 'E2' designation might refer to a specific lead type (e.g., straight leads, formed leads) or packaging method (e.g., tape and reel).
