MLVA04V14C090 is a TVS – Varistor, MOV, specifically a Varistor, stands for Variable Resistor. This device is used to protect against transient over-voltage conditions and is typically used in power and audio applications. It is designed to absorb and shunts transient spikes of energy, protecting sensitive components and circuitry from damage.

Application field and working principle

MLVA04V14C090 is designed to protect sensitive components and power supplies from transient overvoltage spikes, such as those caused by lightning strikes or power system switch-on transients. It acts as a low impedance voltage source, provided the applied voltage is below the device\'s rated voltage. When the applied voltage exceeds the rated voltage, the device critically damps the transient, limiting the peak voltage and current, thereby protecting the components and power systems from over-voltage damage.

The device also provides ESD protection. It limits or prevents the noise caused by electrostatic discharge to the components and the power system. The device is characterized by its surge-handling ability (in joules), current-handling capability, and voltage-handling capability.

The MLVA04V14C090 is used in a variety of applications, such as automotive, telecom, and communication systems. It is typically used in power and audio applications, where sudden spikes in electricity can cause component or system damage. It is used in Automotive applications, such as power line protection, EMI and ESD protection, and power supply transient overvoltage protection. The device is also used in telecommunications, providing protection to Telecom components like routers and phones, as well as protection to communication equipment like modems and switches.

The working principle of MLVA04V14C090 is fairly simple: when the applied voltage exceeds the rated voltage, it begins to absorb the energy, limiting the peak voltage and current. This has a dampening effect on the transient spike, reducing its peak and allowing the power system to survive the event with minimal damage. The device is characterized by its surge-handling ability (in joules), current-handling capability, and voltage-handling capability.

The MLVA04V14C090 is designed to be reliable and have a long operating life. It is a non-volatile device, meaning that it will not require replacement over time. It is also RoHS compliant and RoHS exemption 5 compliant. This means that it is free of lead, mercury, cadmium, hexavalent chromium, and polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).

The MLVA04V14C090 is a great choice for a variety of applications, especially those that require protection against transient voltage spikes. It is designed to last for many years and is RoHS compliant, ensuring that it will keep your sensitive components and power systems safe from over-voltage damage.
