Mobile Phone Smd 2520 Tcxo Crystal Oscillator 19 200mhz 0 5ppm 3 3v - China

price: check with company for price

SMD 2520 Crystal Oscillator TCXO 19.200MHz 0.5PPM 3.3V product application 19.2M is commonly used in mobile phone . product features TCXO temperature compensated crystal oscillator is a quartz crystal oscillator frequency variation generated by the additional temperature compensation circuit makes the variation of ambient temperature reduction. Its temperature compensation principle is by changing the load capacitance in the oscillation circuit, the temperature compensated resonator due to frequency drift caused by the variation of environmental temperature. TCXO is divided into two types, direct compensation and indirect compensation. Industrial grade crystal commonly known as: wide temperature high temperature crystal, crystal and so on, is that in industrial grade crystal, at least the working temperature than the civilian level of -20 - 70 degrees wide, its working temperature is -40 and 85 C, chip cutting type is BT, these two points is very critical. product advantage 1.Our products are all original and new from manufacturer. It must be work if the model number is correct. 2.We have advanced testing equipments 3.Get the international standard management sysem ISO9001, RoHS 4.All products before sending client, we make 72 hours aging test 5.We have 180days warranty 6.During the guarantee period, if the items you purchased from our store are out of perfected quality, pls notify us within 3 days after delivery, we will return the new products when we got your message.
