The MLVA04V09C130 is a nonvolatile polymer varistor developed and manufactured by China based Polymer Asia Electronics. It is a compact device specifically designed for over-voltage protection of low voltage and low cost consumer electronics. It is ideal for use in low voltage power supplies, home appliances and audio equipment.

The principle of operation of the MLVA04V09C130 is similar to that of a traditional voltage-dependent resistor (VDR), also known as a varistor or metal oxide varistor (MOV). A VDR is composed of two electrodes and a dielectric layer, usually made up of zinc oxide particles. When a voltage of sufficient magnitude is applied across the VDR, the particles become conductive, allowing current to flow and providing a conducting path for the excess voltage. The VDR acts as an absorber for any large and sudden increases in voltage, thus providing protection for the device or system.

The MLVA04V09C130 is designed for use in consumer electronics, such as television sets, home appliances, toys, and other consumer electronic equipment. Its operation is dependant on the value of voltage that is applied to it. It has a maximum sustained operating voltage (Vmax,) of 13V and a nominal breakdown voltage of 5V. It also has a maximum peak transient operating voltage (Vto) of 18V and a maximum power rating of 150 mW.

The MLVA04V09C130 is a cost-effective way to protect electronic components from high voltage spikes. It has a high surge current rating and is designed to minimize the effects of external electrical surges. Its wide operating temperature range of -45°C to 125°C allows for use in a range of applications, including automotive, industrial, consumer, and personal electronics.

In the event of a spike in voltage, the MLVA04V09C130 will absorb and divert the excess energy, thereby protecting the device or system from damage. Its superior clamping characteristics provide excellent transient suppression performance. The low leakage currents and low capacitance ensure that the device does not interfere with the signal being transmitted, thus enabling reliable operation.

The MLVA04V09C130 is an excellent choice for protecting low voltage and low cost consumer electronics from voltage spikes. Its high surge current rating and low capacitance make it ideal for a range of applications, while its wide operating temperature range enables reliable operation in a range of environments. Its superior clamping characteristics provide excellent transient suppression performance.
