• Communication equipment
• Industrial control systems
• Consumer electronics
• Automotive electronics
• Data lines

Features

• High surge current capability
• Fast response time
• Low clamping voltage
• Compact size
• RoHS compliant
• Through-hole mounting

Benefits

• Protects electronic components from damage due to voltage surges
• Improves the reliability and lifespan of electronic equipment
• Reduces downtime and repair costs
• Complies with safety standards

Technical Specifications

While detailed specifications require consulting the official Panasonic datasheet, surge absorbers like the ELT3K101B typically have the following characteristics:

• Maximum Surge Current: Specified in Amperes (A), indicating the peak current the device can withstand.
• Clamping Voltage: The maximum voltage the device will allow to pass through during a surge event.
• Breakdown Voltage: The voltage at which the device begins to conduct significantly.
• Operating Temperature Range: Typically -40°C to +85°C.
• Capacitance: A critical parameter, especially for high-frequency applications, as higher capacitance can attenuate the signal.
• Package: Through-hole

The ELT3K101B is typically connected in parallel with the circuit being protected. When a voltage surge occurs, the TVS device rapidly conducts, diverting the excess current away from the sensitive components. Always refer to the Panasonic datasheet for detailed electrical characteristics, application notes, and safety precautions. Proper selection and application of surge absorbers are crucial for ensuring the reliable operation of electronic equipment in harsh environments.
