The ABC’s of Littelfuse Multilayer Suppressors is a supplemental document to the Littelfuse Multilayer data sheets. The document serves as a foundation for understanding the basics of the multilayer suppressor, answering specific questions such as what is the capacitance of the multilayers, and what is the recommended soldering procedure?
A variety of Multilayer Suppressors are available depending on the maximum system voltage
In case you're not familiar, the Littelfuse Multilayer Suppressors is a protection device covering a broad range of applications and circuit components. Specifically, the device suppresses transients within the circuit board to protect components and circuit functions by first clamping the transient and then dissipating its energy within the suppressors. They are similar to Metal Oxide Varistors, MOVs, because they are voltage dependent, nonlinear devices that display a bidirectional clamping characteristic.
The suppressors are available in a wide range of designs to accommodate varying suppression requirements. To select the correct model it's important to know the working voltage or maximum system voltage, the type of transient that is going to be suppressed, and finally which component or circuit needs protection, essentially what level must the transient be suppressed to.
The Multilayer Suppressor can be used in conjunction with a wide array of products such as computers with the many peripheral devices including I/O interfaces, facsimile and printers, automotive electronic modules, medical equipment such as electronic diagnostic instruments, power supplies, microprocessor-based controls, laser diode devices, and many more.
