yeah RS are an option. I need some other parts too and those guys have some of them. so if the shipping isnt too bad i'll just go with Banzai. at 14 bucks each I can almost PAY for the shipping from banzai with the price difference. gotta love these places like RS and farnell in OZ that say they have 'free shipping' when all of the parts they sell are increased in price easily enough to cover the shipping. farnell once tried to charge me a 1000% markup on a common mode choke when compared to mouser. 1.40 at mouser and 13.85 at farnell

yes,

Its a very hard choice which way to go if you don't have a reasonably large order. Digikey now charge a flat $30 postage, so I usually accumulate wants until it represents a % overhead I can live with.

yeah, if over 160-170aud I always go mouser, because of free fast shipping and they have a better range and prices of some things than digikey. we should stay in touch. I make orders regularly and throw in with a friend in sydney and split shipping including the local postage. digikey have a better range of smd R's, C's, ICs and fets. its a pity that there is no one place that carries everything.

sorry for the OT guys

Default 12v relay alternative?

Mouser have a (new?) 12v Panasonic relay - the TQ2-12V-3. I couldn't find a reference to the -3 in the datasheet. Does anyone know whether this relay will work and be an appropriate substitute for the Omron/original Panasonic part?

I'm placing an order with Mouser so would prefer something from there - I know Banzai have the Omron available if this doesn't work out.

Thanks.

Justin.

I've found this in the datasheet:

Notes: 1. AgPd stationary contact types available for high resistance against contact sticking.
When ordering, please add suffix 3 like TQ2-12V-3.


any experience of this type for the DCB1?

Thanks.

Hi
I've got both MUR860G and BYW29-200G.
What is the best suited for Blue DCB1 ?
Cheers

Got my special 65VA doubled shielded audio transformer today but im still waiting to the Texas Components resistors.

What you see on the transformer is a small nice circuit around the Sharp SS-Relais S202.
With it, i just need to switch a small 12VDC line not the complete 230VAC in the final case.

What is the ideal IDSS for the B1 matched SK170s please?

I note that around 8-10mA is stated as preferable in the notes, but that GR grade (less than 6mA) was Nelson Pass' spec in the original B1.

Also, I currently have a 100uF electro as led bypass cap. What do I need to know to decide upon putting a film cap in there, and the value to choose.

Many thanks as always.

Around 7 to 8 is nicer. GR would work too. Plastic cap is ok only for full leds voltage reference 10V DCB1, not in reg only use with added resistor. 0.22uF was alright, but it can do ok with higher too if you got it in better quality. In general a preference after listening area.
