How about RFI Killer from stillpoints?

from the second link:
"If the circuit is housed in a metal case, that RFI will be simply reflected back into the circuit! It's this type of RFI that the Stillpoints ERS material is mainly designed to deal with. And it works by absorbing the RFI, and dissipating it as heat. Because it does that, there is no need to have it connected to ground as would be the case with conventional shielding."

睇介紹應該係同一類型既物料，但效果就要試過先知

寬度        8.26" (210 mm)
長度        11.7" (297 mm)

我反而覺得就算do到都正常，因為呢類吸波物料有佢針對既frequency range，八達通幾多我就唔清楚
另外師兄 ...

係do 唔到的，因為本身好多人都係用佢黎比八達通用，我以前賣唔小

Guys,

AB5000S is the series name of this product. The difference between AB5020/030/050/100S is the thickness of the sheet (0.20/0.30/0.50/1.00 mm respectively). The thickest one gives the best performance.

Datasheet as follows:

淘寶有售，想知有冇料到，剪一塊出黎放係八達通前面，落7仔do唔到就係正常，我係用黎放係銀包，但CAS本身 ...

係反射定吸收EMI?
似係吸收EMI喎. 咁唔會"無得走"啦.

I would buy AB5100S instead of AB5050S.

5100s 自然更好, 但價錢是３倍，一個機箱大概要１米左右

吸嘅頻率強度有唔同

但記住呢d 嘢都系要鎮用, 用多唔一定好!

是的。所以一直都無用，太懶去試。
