Hitachi 2SC2547E transistors - perfect old stock!

Hi All,

My surplus clearout continues...
This time I have to offer approx 200pcs of Hitachi 2SC2547E transistors - low frequency, NPN 0.1A 120V low noise (ideal for audio preamps etc)

These are used in the 'High Octane RIAA preamp' and other low noise pre-amp/amp projects.

Datasheet here:
http://www.datasheetarchive.com/2SC2547E-datasheet.html

These are **genuine new old stock Hitachi devices**, bought from an official distributor well over a decade ago (Pre-Renesas days!).
These are *not* an equivalent, fake or other copy.
These excellent transistors are not often seen now, especially in good number.

This is a scarce opportunity to obtain some of these now very sought-after devices.

Price GBP1.50 each
or 10 for GBP13.50 (10% saving),
or 25 for GBP30.00 (20% saving)
or 50 for GBP55.00 (over 25% saving)
or 100 for GBP99.00 (over 33% saving)

I tested a small batch with my Atlas DCA55 semiconductor analyser and the hfe's were in the range of 450-500, incase that helps.
I could match small groups a bit tighter for a small fee - just ask.

Payment via Paypal accepted.

Postage up to 25pcs: UK GBP2.00, Europe GBP3.50, Elsewhere GBP5.00
Postage 50 or 100pcs: UK: GBP3.50, Europe GBP7.50, Elsewhere GBP9.00 (tracked mail)


If you need them, get in quick before they are gone or risk buying bulls**t copies elsewhere!

Please leave message here and send a PM if you'd like some.

Cheers,
Rob

A quick update:
I had more of these transistors than I thought - about 100 more!
I've taken the time to test every single one of these 2SC2547E's to get the best matching possibilities.
[For those who've already ordered, your transistors are packed up and on their way later today.]

I have remaining four groups of 2SC2547E:

24pcs @ hfe 420-430
Price for all 24 as a *matched* group GBP 35.00

46pcs @ hfe 460-470
Price for all 46 as a *matched* group GBP 68.00

56pcs @ hfe>520 (~650 was the highest if I recall)
Price for all 56 as an unmatched group GBP 60.00

+ I have around 100 or so with hfe under 420 @ GBP1.25 each (min order 10) - please enquire about those.

+ Shipping costs as stated earlier in the thread.

Please leave a brief message here in the thread & send a PM if you'd like some.
These have been very popular - get in before they're gone!

Cheers,
Rob
