hey
i went 2 RS-compnents 2day for wallin jig2. though the shop doesnt stock everything.
im missing:
1* 8ohm non inductive 20W 5% resistor
8* 16.2ohm 1/2W 1% resistor
i found the 8 ohm on parts express,
but a 16ohm 1/2W 5% was the cloest i could get for the 16.2
plus they have their $50min fee which i wont reach...
so any clues where i can get these last couple from.
much appreshiated jens. |

with the 8 16.2ohm 1/2W 1% resistors there are two required results obtained when they are wired in series/parallel:
16.2ohm 2W resistor (wired series and parallel)and
4.05ohm 2w resistor (wired all in parallel)
i was wondering if it would b fine 2 make a slight adjustment on the values by using 2 15ohm and 2 18 ohm in each arrangement giving:
16.5ohm and
4.09ohm.
would this slight change be a significant difference. im not electrically minded....
much aprreshiated |

| What are you going to use these resistors for? What are the precision demands? |

im using the resistors for Wallins jig II
R5, R4 are the made up resistors
R1 is the 8ohm
http://mysite.verizon.net/tammie_er.../jig2/jig2.html
i think ill have 2 ship from over seas.
Eric wallin on his page recommends DigiKey BC16.2ZCT-ND (16.2 ohms) or radio shack a 16 ohm... as long as the final value ends close to 16ohm and is measured properly for correct callabration.
but this resistor 16.2 ohm is .6w i have no idea what that does, i assume it would be ok. i think it just means it can adsorb more wattage? |

I don't usually recommend them (there are much cheaper places around for 99% of what most of us need) but Farnell can almost certainly get you what you want and deliver it to your door in a couple of days or less. Will certainly be quicker and cheaper than ordering from overseas.

Hi,
16r2 = two series connected 8r2//1k3 or 18r//160r.
Use 500mW or 600mW 1% for each resistor.
Over rating the dissipation should make no difference to the circuit. |
