4 MHz Crystal + 20pF Capacitors - MCU Clock pol1457 we have plain 433MHz packetKeep your microcontroller tickin' with a a fancy timing crystal. This 4. 000 MHz model comes in a HC49 US 'short style' standard package and is breadboard friendly and easy to use with any microcontroller or device that requires an external crystal. We even include two 20pF capacitors! The crystal has 30PPM tolerance, 50PPM stability so it's good even for high precision needs (USB timing, long term time keeping, RF PLL VCO driving). To use, connect
