Crystals are interesting components of many electrical and electronic circuits, and they have wide variety of applications. The MA-406 4.9152M-A is an example of a crystal that is used in many electronic circuits and is RoHS (Restriction of Hazardous Substances) compliant. In this article, we will briefly explain what RoHS is, the application field and working principle of the MA-406 4.9152M-A.

The RoHS directive, also known as Directive 2002/95/EC, sets limits for the use of hazardous substances (e.g. lead and cadmium) in electronic and electrical equipment. This directive is designed to reduce the environmental impact of such equipment and to ensure that it is safe for the people who use such equipment. The MA-406 4.9152M-A is RoHS compliant, meaning that it adheres to the requirements set forth in the RoHS directive.

The MA-406 4.9152M-A is an oscillator crystal with a frequency of 4.9152 MHz. It is typically used in radio frequency (RF) circuits, such as those found in doorbells, walkie talkies, and remote control devices. The crystal is designed to have a low jitter response and is able to withstand temperatures between -40 and 85 degrees Celsius. The circuit that it is a part of will determine the exact frequency of the oscillation, but with this crystal, one can expect an accuracy range of +/-50 PPM (parts per million).

The working principle of the MA-406 4.9152M-A is quite simple. The crystal itself is made out of two thin layers of quartz that are sandwich together in an X-Y axis. When the crystal is placed in an electric circuit, a voltage is applied to the crystal. This voltage causes the crystal to vibrate at its natural frequency and produce an oscillating signal at the desired frequency.

The MA-406 4.9152M-A is a reliable, RoHS compliant oscillator crystal that can be used in many different types of radio frequency circuits. Its simple working principle and temperature tolerance make it an ideal choice for many applications.
