AMCV-0603-090-C300N-T

The AMCV-0603-090-C300N-T is a varistor, also known as a voltage-dependent resistor (VDR). Varistors are used to protect circuits from large spikes in voltage due to lightning, power surges, and other overvoltage conditions. The AMCV-0603-090-C300N-T has a response time of less than 1µs, making it an ideal choice for use in surge protector applications such as television sets, computers, telephone networks, and power supplies.

The working principle of a varistor is based on the fact that the device exhibits an increase in resistance as the voltage across its terminals increases. This behavior is known as a negative resistance. In normal operation, the varistor has a low resistance, allowing current to flow freely. When an overvoltage occurs, the resistance of the varistor increases, dissipating the extra energy as heat. This prevents the circuits that it is protecting from being damaged by the overvoltage.

The AMCV-0603-090-C300N-T is a chip varistor, meaning that it is physically smaller and has a higher current capacity than other types of varistors. It is a 0603 size, meaning that it is 0.06" x 0.03" in size. The “C300N” in the part number indicates that the maximum breakdown voltage is 300V. The “T” indicates that the maximum peak pulse current is 35A. The AMCV-0603-090-C300N-T has a capacitance rating of 0.090µF, a temperature coefficient of -0.2%, and a dissipation factor of 0.95.

The AMCV-0603-090-C300N-T is suitable for a wide range of applications, such as AC-DC power supplies, power over Ethernet (PoE) systems, telecom equipment, audio equipment, automotive electronics, computers, home appliances, and LCD displays. In each of these applications, the AMCV-0603-090-C300N-T is used as an overvoltage protection device to prevent damage to sensitive components and circuitry.

In summary, the AMCV-0603-090-C300N-T is a varistor, also known as a voltage-dependent resistor (VDR). It is commonly used in surge protection applications as it has a response time of less than 1µs. The chip varistor is 0603 size with a maximum breakdown voltage of 300V and a maximum peak pulse current of 35A. It is suitable for AC-DC power supplies, PoE systems, telecom equipment, audio equipment, automotive electronics, computers, home appliances, and LCD displays.
