Overall, if the regulator's pros outweigh its cons for your specific application, it may be a worthwhile investment.
Recommendation:If you require a high-quality voltage regulator with a wide input voltage range and adjustable output voltage, the UA78HG AKC UA78HG Voltage Regulator from Fairchild is a suitable option. However, if you need a regulator with a higher output current or built-in protective features, you may want to consider other options available on the market.
New Fairchild UA78HGkc adjustable voltage regulator note this purchase is for a UA78HGkc regulator, not the UA78HGAKC shown in the ad photo. It will defeat your ability Roget combined shipping.
I simply don't have the time Tod all that extra work for every customer.
Although this chip is brand new, it is new old stock, Adas such, it may contain surface scratches or minor surface blemishes.
Unlike so many of the other chips being sold here,this one is not of questionable reliability that has been pulled used and untested from other equipment. However, I do not know if there is a difference in electrical specs between the two regulators.
With that said,other than the part, the UA78HGAKC regulator shown in the ad photo looks identical to Thea 78 hajj and the pins are numbered the same as well. The reason is simple.
