Use these engineering checklists to prepare a faster, clearer component review. EKT can support family selection, incumbent-part comparison, document requests and sample planning.
Share the electrical stress, normal operating range, worst-case fault, temperature, mechanical limits, regulatory targets and annual demand. We will use that information to identify suitable product families and the specifications that still require confirmation.
Prepare continuous operating voltage, varistor voltage, surge waveform, peak current, energy, clamping target, package and environment.
Define stand-off voltage, breakdown and clamping limits, pulse power, interface capacitance, polarity, package and qualification needs.
Provide hold current, trip current, maximum voltage and fault current, trip-time target, ambient derating and PCB footprint.
Define rated current and voltage, breaking capacity, fast or time-lag response, pulse tolerance, package, approvals and operating temperature.
Prepare nominal resistance, B value or switching behavior, tolerance, temperature range, dissipation, response time and mechanical format.
Specify capacitance, rated voltage, dielectric, tolerance, package size, temperature characteristic, frequency and application conditions.
Submit the incumbent manufacturer and part number together with the parameters that cannot change. Equivalence is confirmed only after controlled datasheet comparison and testing.
Request cross-reference support →Request the latest available controlled datasheet, dimension drawing and applicable quality documentation for the selected EKT series.
Request technical documents →Tell us the application, sample quantity, evaluation schedule and required approvals so the right series and test priorities can be reviewed.
Discuss samples →Record normal operation, the protection target and the failure mode to prevent.
Apply temperature, voltage, current, pulse and lifetime margins appropriate to the project.
Review package, performance, qualification, availability and controlled documentation.
Test samples in the final circuit under normal, abnormal and environmental conditions.
Send your application, key parameters, incumbent part number and estimated annual quantity.
