NDK announces a series of ultra small, thin, surface mount crystals. The NX2520DA series measures 2.5 × 2.0 × 0.6 mm. They exhibit optimum electrical performance required for miniature wireless applications. The NX2520 is available in a fundamental frequency range of 20 to 80 MHz. Standard frequencies for these crystals include 20.000, 22.5792, 24.000, 24.756, 26.000, 27.000, 28.63636, 32.000, 40.000, 44.000, and 48.000 MHz. Their frequency tolerance is ± 10 ppm to ± 100 ppm over the operating temperature range of 10°C to +60°C. The NX2520DA series ESR (equivalent series resistance) is 100 Ω maximum in the frequency range of 20 to 30MHz and 50 Ω maximum in the frequency range of 30 to 80 MHz. The NX2520DA is in a ceramic based, metal covered, lead-free package, and they meet the requirements for re-flow profiling using lead-free solder.
