Schurter's compact and high -performance fuses enjoy a high reputation in the industry. Its OGN series open fuse seats used in the 5x20mm fuse are no exception. On the basis of the existing THT and SMT models, this series of products currently launch a model that can be compatible with the welding process that can return to the Tongkou (THR).
SMT components are used for PCB assembly. Ideally, such components are compatible with reflux welding processes, thereby achieving complete automation of assembly. Although the THT component provides panel installation solutions, it is usually not necessary to cope with the strict requirements of the reflux welding process. In the above situation, a welding step must be added. This additional handmade steps required for THT assembly not only take time, but also cause additional errors.
The Tonghong reflection welding (THR) component provides a solution to respond to the above problems. This product not only has the characteristics of THT installation on the PCB, but also to withstand the high thermal stress of the return welding furnace. First, leak the THR component to the pink pores, and then make it passed through the paste. With the melting of the tiny paste in the return welding furnace, the liquid welded shrinks into the puppet hole under the action of wetting and capillary, thereby forming a welded joint.
Like the existing OGN series open fuse, the OGN THR model is suitable for various types of fuses of 5X20mm. According to the UL and CSA standards, this series of products can provide a model with a rated current of 16A under 500VAC/VDC. According to the VDE standard, it can provide a model with a rated current at 500VAC 10A and 16A. This series of products can choose whether to add a hood. According to the IEC standard, the rated acceptance power at the ambient temperature of 23 ° C is 4W/16A when the ambient temperature is 23 ° C. The acceptance of the black cover model is 4W/10A, and the power of the transparent cover model is 2.5W/10A. The allowable range of environmental air temperature is -40 ° C to 85 ° C. The OGN series products can also meet more stringent fire safety requirements and meet the hot silk test requirements of IEC60335-1. OGN THR and OGN Tht are completely backward.
