Kingtronics International Company — Circuit Protection Expertise

In compact electronic circuits and high-density PCB layouts, reliable operation depends heavily on effective transient voltage suppression. Typical field issues include sensitive ICs failing under unexpected electrostatic discharge (ESD) events, communication ports degrading from voltage surges, and signal interference caused by components with improper electrical characteristics. When this happens, system uptime and reliability are compromised.

Instead of simply relying on basic component choices, a more robust approach is to evaluate the underlying technology: what makes a multilayer chip varistor (MLV) capable of surviving rapid transient events while maintaining signal integrity? Once the self-protection and low capacitance requirements are clear, selecting the right component becomes a structured engineering decision rather than guesswork.



Frequently Asked Questions (FAQ)

What is a multilayer chip varistor?
A multilayer chip varistor is an SMT transient voltage suppression component used to protect compact circuits from ESD and surge events.

What is an MLV used for?
MLVs are commonly used for ESD protection on signal lines, USB interfaces, communication ports, mobile devices and automotive electronics.

What is the difference between MLV and MOV?
MLVs are compact chip components for signal-line ESD protection; MOVs are typically used for higher-energy surge protection in power circuits.

Why is low capacitance important for ESD protection?
Low capacitance helps protect high-speed data lines while reducing signal interference or distortion.

Is VKT suitable for USB interface protection?
Yes. VKT is positioned for high-speed data line and USB interface protection, with low capacitance and bi-directional ESD protection.

What package sizes are available for VKT MLV?
VKT datasheet lists 0603, 0805, 1206, 1210, 1812 and 2220 inch-code package sizes. (Kingtronics)

Which VKT series options are available?
VKT includes E for ESD, G for Normal and H for High Power series options. (Kingtronics)

Compact SMT Protection for High-Speed Electronics

In modern high-density PCB layouts, electrostatic discharge (ESD) and voltage transients pose severe risks to sensitive ICs. Kingtronics VKT Multilayer Chip Varistors offer fast clamping speeds, low clamping voltage, and superior bi-directional transient voltage suppression capabilities in standard surface-mount packages.

Using the VKT Datasheet as a Reference

For engineers who prefer to work directly from technical parameters, a consolidated datasheet is essential. The VKT Series covers multiple packaging options and performance grades.
