The BK12018002-H is a Discharge Tube (GDT/TSS) Axial RoHS manufactured by Yageo. This part is used in low voltage DC circuits, surge protection, or as a snubber circuit. This device provides a high level of protection and is designed to protect against high voltage spikes, current overloads and lightning strikes. This device is RoHS compliant, meaning that it uses safe materials that do not adversely affect the environment. It is an axial component, which means it has two equally spaced leads that extend from its cylindrical body, and it can be mounted to a surface or supported by stand-offs. The BK12018002-H has an impedance of 2k? at one MHz, a max impulse voltage of 1.2/50µs and a max operating temperature of 100°C. This device is an excellent choice for a variety of applications, especially in harsh environments where environmental protection is necessary.
