Customer Questions & Answers
What are the exact dimensions and package type of the crystals in this pack?
Each crystal comes in a standard HC49/S package, with approximate dimensions of 11.5 mm long, 4.7 mm wide and 3.5 mm high. The pins are about 3.5 mm long and the spacing between them is 4.88 mm. The HC49/S format is considered compact and is compatible with most DIP sockets and prototyping boards.
What is the typical frequency tolerance and thermal stability of these crystals?
The typical frequency tolerance in HC49/S packages is usually between ±20 ppm and ±30 ppm at 25°C, with approximate thermal stability of ±30 ppm within the range of -20°C to 70°C. It is recommended to check the manufacturer’s datasheet for each specific batch, as these values may vary slightly depending on origin.
Do these crystals require a specific load circuit, or can they be used directly with any standard microcontroller?
Normally, HC49/S crystals are designed to work with a typical load capacitance of 18 pF to 22 pF. They are compatible with most microcontrollers, but it is advisable to adjust the load capacitors according to the specifications of both the microcontroller and the crystal to achieve optimum accuracy.
Are there any risks of damage from soldering or handling, and what practices are recommended to ensure durability?
Quartz is fragile and can be damaged by impacts and excessive temperatures. It is advisable to solder at temperatures below 300°C for less than 3 seconds per pin to avoid internal cracks. Handle the parts by the pins, avoiding sideways force or twisting. Using ESD precautions (protection against electrostatic discharge) also helps extend the product’s service life.
What frequencies are included in this quartz crystal pack?
It includes 10 frequency values: 6MHz, 8MHz, 10MHz, 11,0592MHz, 12MHz, 16MHz, 24MHz, 24,576MHz, 25MHz and 40MHz.
What are quartz crystal oscillators used for?
They are used to generate a stable frequency signal in electronic circuits, such as clocks, microcontrollers and oscillators.
What type of package do these crystals have?
They are packaged in HC49S format, standard for mounting on electronic boards.
How many units are included per frequency?
The pack contains 5 units of each of the 10 frequency values, making a total of 50 crystals.
