On the website http://routerboard.com/ I read that only R5H minipci card has an integrated surge protector but one of our MT distributor on your website:
Card 2,4 GHz R2N Mikrotik mini PCI, 320mW, 300 Mbps, Integrated surge protector

Card 5 GHz R52N Mikrotik mini PCI, 320mW, 2.4 & 5 GHz, 300 Mbps, Integrated surge protector

Card 5 GHz R5H Mikrotik mini PCI, 320mW, Integrated surge protector

Is an misinformation?

the product brochure in routerboard.com is always more correct than some other website.

R5H and R52Hn have ESD protection. That’s all
