The device has a bunch of components that are rarely used on other chargers. They are used to reduce electromagnetic interference.
It is also worth noting the very tiny dimensions of the components used. In the photo below, you can compare the size of the resistors with rice and mustard grain.
To sum it up, it's worth noting that Apple's power adapter is a high quality power supply. Apple went to extra cost to reduce EMI so as not to harm the touchscreen. Apple's iPhone charger incorporates a wealth of technology in a small space, further proving the excellence of Apple's engineers.
