Hc49 Crystal

What you need to know about Hc49 crystal?

What is meant by Hc49 crystal?

An electrical circuit could employ a crystal oscillator package of the Hc49 crystal. It is an inexpensive oscillator that operates in several kilohertz to several megahertz ranges. With measurements of 5.0mm x 7.5mm x 9.0mm, the HC49 packaging is a metal can. The usage of it in microprocessors, clocks, and other timing circuits is rather prevalent. From a few kilohertz to many megahertz, crystals in the HC49 package are offered in various frequencies. They are frequently employed as the reference frequency source for electronic circuits’ timing and synchronization.

A different application of Hc49 crystal:

For frequency management in electronic systems, Hc49 Crystal is a particular crystal oscillator. It offers a dependable timing solution at a reasonable price for many different applications. One of the most common crystals in the world, it is offered in both through-hole and surface-mount packages. This quartz crystal oscillator, which is tiny and inexpensive, is utilized in electrical devices for several different purposes. Due to its excellent precision and stability, this oscillator is frequently utilized in various applications, including those for computers, smartphones, and other consumer electronics. The many of these crystal varieties, their uses, and the best practices for choosing them for use in circuits are covered on this page.

Types of Hc49 crystal:

This crystal is the best option for any electronics project since it offers a wide frequency stability range. The crystal unit was described by determining the frequency of its oscillations at various voltages and temperatures. The characterization process was carried out using an oscilloscope and a frequency counter. These crystals, which are tiny quartz-based oscillators used in electronic circuits for timing and frequency control, come in various shapes and sizes. HC49 crystals come in a variety of common forms, such as:

Hc49 crystal

 This is the common HC49 crystal package, which is rectangular and is around 10mm in length and 5mm in width. It is connected to the circuit via two metal leads on it. The rectangular-shaped HC49/S crystal has a length of around 10mm and a width of approximately 5mm. It is a typical-sized HC49 crystal. The circuit is connected to it using the two metal leads on the device.

  • The resonance frequency, or the frequency at which it oscillates naturally, is one of the key properties of the HC49/S crystal. It is noted in the manufacturer’s datasheet that an HC49/S crystal’s resonance frequency normally falls between a few kilohertz and a few megahertz.
  • The tolerance, stability, and ageing of the HC49/S crystal and its resonance frequency are key characteristics that affect its performance. The tolerance of an HC49/S crystal is normally expressed in parts per million and is the largest difference between the crystal’s real and nominal resonance frequencies (ppm).
  • The change in an HC49/S crystal’s resonance frequency over a certain temperature range is referred to as stability, commonly expressed in ppm. An HC49/S crystal’s ageing is measured in ppm per year and is based on how its resonance frequency changes over time.
  • The HC49/S crystal is frequently employed in electronic circuits that need accurate timing or frequency control, such as microcontrollers, clocks, and radios. A crystal oscillator circuit, which amplifies the signal generated by the crystal and makes it useable in the circuit, is frequently used in combination with it.
  • HC49/U:

This rectangular crystal has a length of around 10mm and a width of roughly 3.2mm. It is a thinner variant of the HC49/S crystal. It is connected to the circuit via two metal leads on it.

  • The HC49/U crystal has a rectangular form, is thinner than the HC49/S crystal, and is about 3.2mm in width and around 10mm in length. The circuit is connected to it using the two metal leads on the device.
  • Similar to the HC49/S crystal, the HC49/U crystal’s performance in an electrical circuit is determined by its resonance frequency. The datasheet provided by the manufacturer contains information on the resonant frequency of an HC49/U crystal, which is normally in the range of a few kilohertz to a few megahertz.
  • The tolerance, stability, and ageing of the HC49/U crystal are characteristics that affect its performance and resonant frequency. The tolerance of an HC49/U crystal is normally expressed in parts per million and represents the largest difference between the crystal’s real and nominal resonance frequencies (ppm).
  • Microcontrollers, clocks, and radios are electronic circuits that frequently employ the HC49/U crystal. When a thinner package is required, or there is a shortage of room on the circuit board, it is frequently preferable to the HC49/S crystal. The HC49/U crystal is often combined with a crystal oscillator circuit, just like the HC49/S crystal.

 

Benefits of Hc49 crystal:

Oscillators are electrical circuits that produce periodic oscillating signals, and oscillators frequently employ these crystals. In oscillators, these crystals have several advantages, such as:

  • Size: 

Due to their modest size, HC49 crystals can be used in electrical products designed to be portable.

  • Frequency stability:

The high-frequency stability of the Hc49 crystal ensures that they continue to oscillate at the same frequency throughout time.

  • Cost-effectiveness: 

In comparison to other types of oscillators, HC49 crystals are comparatively cheap.

  • Wide frequency range: 

These crystals come in a wide range of frequencies, making them appropriate for several applications.

  • Ease of use:

Simple integration into electrical circuits and low need for additional components make HC49 crystals simple.
