A 27 termination occurs when a transmission line is terminated with a device that matches its characteristic impedance. Because of the low cost of its packages, the 44-BSOP (0.295, 7.50mm Width) is well known in the electronic industry. Packaging follows Tube's material specifications. Using Surface Mount, you mount it on a PCB. A maximum operating temperature of 0°C~70°C should not be exceeded. It is a SCSI-qualified material for standard applications. Devices from the supplier are packaged in 44-SSOP.
