Reflowable Thermal Protection (RTP)

Reflowable Thermal Protection

Our RTP devices are low resistance, robust surface mountable thermal protectors with a set open temperature that can be installed using Surface Mount Device (SMD) assembly and reflow processes.

Built to endure reflow without opening. RTP devices only open when their internal junction exceeds the device’s specified open temperature, in thermal runaway events, and before the melt temperature of typical lead free solders. While operating under normal component windows, the device remains shut.

Activation Temperature

RTP devices have a set activation temperature and can be reflowed at temperatures up to 260°C, providing a high degree of flexibility in placement of thermal protection. In addition, the devices help lower assembly costs by eliminating manual and special handling processes. Once they have been reflowed onto the PCB, a simple arming procedure is all that is needed to ready the device so that they will activate at the set temperature.
