Photovoltaic power generation currently accounts for about 10% of energy consumed in Japan. When lightning strikes, it occasionally causes abnormally high voltages (surges) in the surrounding transmission lines. These surges can sometimes penetrate the electronic circuits of solar panels, causing them to malfunction. To prevent this, a component called a surge ab- sorber plays a role in absorbing surges and protecting electronic devices.
Surge absorbers don’t operate at normal voltage. Rather, they are active in response to surges that penetrate the electronic device. For this reason, quicker responsiveness to surges enhances the protective performance. Mitsubishi Materials provides society with highly responsive, high-performance surge absorbers by using the Micro-gap method, our proprietary design technology.
The demand for surge absorbers is steadily increasing due to various factors, including the rising frequency of lightning strikes caused by abnormal weather conditions and the need to accommodate smaller electronic devices. Our company will strive to develop smaller, more durable surge absorbers.

The LITOL / LTP series is a product developed to protect all types of electronic devices from abnormal voltages, such as lightning-in-duced electrical surges (lightning damage), and noises. The product is easy to handle and install, durable against repeated surges, and has a longer product life.
