CGA0805MLA-18351E is a varistor manufactured by CGA Company. It is a surface mount component with a wide range of applications. This varistor has a small size, good reliability, and excellent insulation and anti-interference performance.

It has wide application fields such as precision instruments and computers, telecommunication systems, power supply circuits, micro-computers, automotive electronics, consumer electronics, and numerous other industrial systems. This varistor can be used to provide surge protection by limiting the magnitude and increasing the speed of absorption of transient voltage spikes in a given system. It is also suitable for clamping and suppressing high frequency interference, such as electromagnetic waves, electrostatic noise, and power line interference.

The working principle of CGA0805MLA-18351E is quite simple. It contains a voltage-dependent ceramic element which is finely synthesized from various multilayer substrates and metal electrodes. When the applied transient voltage rises above a fixed threshold, its leakage resistance will suddenly drop and the corresponding current can pass through it freely. This rapid current flow will last only for a very short time, during which the transient voltage can be discharged in a relatively short period. In this way, CGA0805MLA-18351E can provide a reliable and effective protection against transient voltage spikes.

Apart from having a high capacity to dissipate surge current, CGA0805MLA-18351E also has an excellent thermal stability and low leakage current. It operates over a wide temperature range of -40℃ to +85℃, and its rated clamping voltage (VCL) ranges from 6V to 120V. Furthermore, it is also resistant to most common chemicals and oils, and it can provide a maximum pulse current value of 5kA (8/20μs).

CGA0805MLA-18351E is a highly reliable and versatile varistor which can be used in a wide variety of applications, ranging from automotive electronics to precision instruments. Its working principle is quite simple and effective, as it can quickly clamp the applied transient voltage to a safe level and provide a reliable protection against transient voltage spikes. Furthermore, it has excellent insulation and anti-interference performance, excellent thermal stability, and it operates over a wide temperature range. All of its features make it an ideal choice for surge protection applications.
