| Claimed "1/4 watt" through-hole resistors from Amazon seller "Eamasawa" |

I was thinking more their total fragility and tendency to easily blow short circuited. Others tell me this is no longer as bad as it used to be and new auto grade ones are fine. |
| HobGoblyn:
As someone new to this hobby, the huge choice can be overwhelming. For example, if I want a 10uf 50v cap, RS gives me a choice of 101 through hole (plus another 76 surface mount). Sure some of those are the same one in bigger quantities but even so, I end up picking at random and because I’ve read Panasonic are good, if it’s to repair something, I usually choose them. Even if I tick the 5000 hr filter, I still get 7 different Ones (it lists 14 but duplicated in different quantities) to choose from. |

There is a huge variety of parts because of cost. At one end of the spectrum you have requirements for very low and high temperature with very long life, at the other end you have "it just has to last a year". Obviously there is different packaging which create duplicates. RS love to repackage everything where as other will do "cut tape" which is what RS effectively do by repackaging, re-reel give you a reel for and SMD assembly machine with whatever quantity you want or full reel as supplied by manufacturer. For hobbyists purposes you will just want cut tape. re-reeling costs per reel in the case of Farnell £3.50 but if you are an assembly house needing 2500 resistors it's maybe cheaper than buying a whole real of 5'000. As do different specs my thought experiment is that if you multiply all the specs together you will get a number that represents the price. |

Hello, do you happen to know where to obtain the datasheet for these resistors, I have sent an e-mail to the manufacturer but they have not responded. |
| EPAIII:
Simple guidance: if you want a quality electronic part, buy from an electronic supply house, not Amazon. It really is that simple. |
