A three digit code where the first two digits are significant figures, and the third digit indicates the number of zeros that follow these figures (i.e., 500 = 50Ω; 750 = 75Ω; 601 = 600Ω ). Shaft Length: 20S = 13mm Shaft with Knurled, Slotted End Style. 30S = 23mm Shaft with Knurled, Slotted End Style. Blank = No shaft. Nominal Attenuation: 6.5dB (0.7 Attenuation Tolerance). 12dB (1.1 Attenuation Tolerance). 20dB (1.5 Attenuation Tolerance). Dash: Use a dash, with no space before or after the dash, to separate Style and Nominal Attenuation. Example: AT10PK-20dB20S500 Style: P = PCB Mount, No Shaft, Rotor Flush with Housing, 3-Pin Triangular Pattern, Top Adjust. S = PCB Mount, No Shaft, Rotor Flush with Housing, 3-Pin Triangular Pattern, Side Adjust. PK = PCB Mount, Plastic Shaft (available in 2 lengths), 3-Pin Triangular Pattern, Top Adjust Only. Size: 10 = 10mm Square Housing. TOCOS Series Name: AT = Attenuator. Packaging Standard: Bulk Packaging Quantity 100 pieces per box. Soldering and Cleaning Guidelines For soldering, cleaning and other information, refer to the Guidelines and Precautions.
