CR0402 - Chip Resistor How To Order CR 0402 - F X - 8252 G __ Model (CR = Chip Resistor) Size * 0402 Resistance Tolerance F = 1 % ............Used with "X" TCR code only for values from 10 ohms through 1 megohm. J = 5 % ..............Used with "W" TCR code for values from 10 ohms through 5.6 megohms. Used with "/" TCR code for zero ohm (jumper) ......................and for values from 1 ohm through 9.1 ohms. TCR (ppm/C) X = 100 ..............Used with "F" Resistance Tolerance code only for values from 10 ohms through 1 megohm. W = 200 ..............Used with "J" Resistance Tolerance code only for values from 10 ohms through 5.6 megohms. / = -250 to +500 ..Used with "J" Resistance Tolerance code only for zero ohm (jumper), and for values from 1 ohm through 9.1ohms. Resistance Value For 1 % Tolerance: <100 ohms.............."R" designates decimal point (example: 24R3 = 24.3 ohms) 100 ohms ..............First three digits are significant, fourth digit represents number of zeros to follow (example: 8252 = 82.5k ohms). For 5 % Tolerance: <10 ohms................"R" designates decimal point (example: 4R7 = 4.7 ohms) 10 ohms ................First two digits are significant, third digit represents number of zeros to follow (example: 474 = 470k ohms; 000 = Jumper). Packaging G = Paper Tape (10,000 pcs.) on 7 " Plastic Reel Termination LF = Tin-plated (lead free) __ = Solder-plated REV. 04/06 Specifications are subject to change without notice. Customers should verify actual device performance in their specific applications. |
