Frequently asked questions
What is the price of 40 MHz Crystal HC-49U 20ppm 20pF 40Ω in Egypt?
40 MHz Crystal HC-49U 20ppm 20pF 40Ω currently costs 7.5 EGP in Egypt.
Where can I buy 40 MHz Crystal HC-49U 20ppm 20pF 40Ω in Egypt?
40 MHz Crystal HC-49U 20ppm 20pF 40Ω is available from Makers Electronics. Compare the offers above to find the best price.
Can I connect this crystal directly to any microcontroller?
No. The MCU must have an oscillator circuit for an external crystal, and many MCUs support a maximum external crystal frequency below 40 MHz. Check the MCU datasheet first, then add load capacitors as it recommends.
What does the 40Ω value mean?
It is the crystal's equivalent series resistance (ESR) as listed. A higher ESR can make oscillator startup harder, so match it to your oscillator circuit.
