Tape-and-reel packaging is compatible with standard pick-and-place assembly lines; the no-lead format requires a reflow profile with appropriate soak and peak temperatures for the package size.","metaTitle":"ECS-2033-040-BN CMOS XO, 4 MHz, ±50ppm, 3.3V","metaDescription":"ECS-2033-040-BN is an active-standard XO oscillator, 4 MHz CMOS output, ±50ppm stability, 3.3V supply, -40°C to 85°C.
