Model 425 Surface Mount Quartz Crystal FEATURES Standard 2.5mm x 2.0mm Seam Weld Package Fundamental Crystal Design Frequency Range 12 – 60MHz Frequency Tolerance, ±20ppm Standard Frequency Stability, ±20ppm Standard Operating Temperature to -40°C to +85°C Tape & Reel Packaging Standard, EIA-481 RoHS/Green Compliant [6/6] APPLICATIONS Model 425 is a low cost quartz resonator used in a wide range of commercial applications including wearable and handheld electronics, notebooks, tablets, computer peripherals, Bluetooth, ZigBee and USB interfaces. ORDERING INFORMATION 425 M MODE OF OSCILLATION FREQUENCY IN MHz F = Fundamental M - indicates MHz and decimal point. FREQUENCY TOLERANCE @ +25°C 1 = ±10ppm X = ±15ppm 2 = ±20ppm LOAD CAPACITANCE Y = ±25ppm 3 = ±30ppm R = ±10ppm Y = ±15ppm N = ±20ppm 4 = ±30ppm 8 = ±50ppm D = 18pF E = 20pF F = 24pF G = 30pF S = Series K = 8pF J = 9pF A = 10pF L = 12pF C = 16pF TEMPERATURE STABILITY/TEMPERATURE RANGE -20°C to +70°C -30°C to +85°C -40°C to +85°C 1 = ±10ppm X = ±15ppm 2 = ±20ppm 3 = ±30ppm 5 = ±50ppm 1,2 W = ±15ppm 6 = ±20ppm 7 = ±30ppm 9 = ±50ppm 1. Frequency is recorded with 3 leading digits before the ‘M’ and 4 significant digits after the ‘M’ [including zeros]. [Ex. XXXMXXXX (016M3840), XXXMXXXX (022M1184)] 2] There are frequencies that have significant digits after the 'M' that exceed the 4 digits. The remaining digits will be truncated from the CTS part number, but the factory will calibrate to the full frequency desired. Ex. P/N Frequency = Actual Frequency 13M5537 = 13.553750 MHz 14M3181= 14.318180 MHz 16M6666 = 16.666670 MHz 28M6363 = 28.636360 MHz Not all performance combinations and frequencies may be available.
