F5 parts for sale

Got same postage prices for USA 20 Futabas =£2.56 or £7.56 with tracking
Futabas will be precision measured at 100 mA (LM317 circuit from data sheet)

Holco £10 bag of 100 (mixed values maybe) or £0.14 each
FQA12P20 VGS tested at one point and at constant temperature of 50C (+ - 1 C)
£7
FQP19N20 (TO220) £5.00

[Bksabath]

MPC 74 precision measured at 100 mA
£1 each

Quite a few matched values whit in 0.001 Homs or beter

IMO not sure why one may need this precision as a smaller value resistor would compensate for a lazier mosfet

But there you have it.

Hi Just back from Hols in egypt

Yes they are but note FQP19N20 is what I have and is TO 220 as in pictures.

When finished unpacking I will do single point matching
24 V 2A at constant 50C temperature

Checking for additional interest with some local folks. Be back to you soon.

Futaba MPC 74 0.47R

For sale at £1


I have started to measure up a batch of Futabas.
I am using 10V and LM317 as 100.00 mA constant current source.

IMO handy to know which resistor to use as source resistor, a lower value may help a lazier Mosfet.

But then if you want them matched just pick what you want

At first I was using Dip sockets but contact was not reliable and adding about 0.006 Homs to the test.

I got much beter and repeatable measurement with a different socket so I will try to improve on that and start again

In the mean time I have reliable results up to 0.000 Homs repeatable to 0.0000
And the meter is capable to go down to 0.00000

I have a first batch of Futabas ready

Pick your values from table

First came first served

Reserved 10 to be picked

£1 each + P&P

Unfortunately yours truly wrote down the values with permanent marker and first round of measurement was out by about 0.008 Homs (Poor contact on Dill socket adding to test results)
I could not get rid of the marker so values are crossed over.
I am really sorry about that.
I remember now somebody mentioning the use of sticky labels (Papa matching mosfets article)
