The AUML Series of Multilayer Transient Surge Suppressors was specifically designed to suppress the destructive transient voltages found in an automobile. These transient voltages are commonly caused by large inductive energy discharges. The AUML suppressor is manufactured from semiconducting ceramics, offering rugged protection and excellent transient energy absorption. The series is suitable for temperature ranges from -55°C to 125°C, providing temperature-independent suppression characteristics. The AUML suppressors are available in ceramic leadless chip form, eliminating lead inductance and ensuring fast response to transient surges. Compared to silicon TVS diodes, these suppressors require smaller space and land pads, providing greater flexibility in circuit board layout for designers.
The AUML Series of Multilayer Transient Surge Suppressors is specifically designed to suppress destructive transient voltages found in automobiles, such as those from large inductive energy discharges in antilock brake systems, ignition systems, and engine controls. Manufactured from semiconducting ceramics, these devices offer rugged protection and excellent transient energy absorption in a small, leadless surface mount chip form that eliminates lead inductance for fast response times.
