Hi,

   i need a couple of matched FET's (

NTE312 N channel JFET.

Is it possible for element14 to match the FET's and send? Manually matching them would require me to order some 50 odd FETs, which is silly coz i need only a single pair for a prototype project.

Thank you

hello sir , i am making a project of transmitter.whose circuit diagram is shown below.i think this circuit diagram is right for me so i choose it to build my project.but there is one problem comes across me .i've found that i have bc547,bc548,bc337 type transistors only but the recommended transistor in this circuit diagram is bc338 which is not available in any shop in my town..so what can i do ????? can i am allowed to use transistors bc547,bc548 or bc337 in this circuit.actually i have taken this image from a video so the suggestion of using bc338 is given in the video..not given here in the image......please suggest me solution as soon as possible ..i have to complete my project till next morning.....please also tell me the description of the full circuit step by step....thankyou very much sir

Dear Sir,

We are designning micro controller based temp. controller. We want to design to withstand industrial noise,spikes and voltage variations. Pl suggest proper way to shield or suppressors to eliminate the effect of noise & spikes.

thank you.

I have an inquiry for EPCOS Capacitors. Just wonder whether this part number is available or not. This Capacitors are used for Riello UPS 6 KVA.

1. EPCOS B43991-S9228-M2 2200uF 400V

2. EPCOS xxxxxxx 1200uF 250V.

Can you please advise, how I can get them quickly.

Thank you.

Hi, Abishek R Rao,

I am keith from Keii. Nice to get to know you and your esteemed company.

As you are a expert of circuit and i see that there isn`t any infrared camera in your production line and infrared camera is a good tool to inspection circuit, so i am here to recommend you our our Keii infrared camera.

you can view our infrared cameras on our website and if you are interested in any cameras, please contact without hesitation.

Thanks and best regards.

Hi Abhishek,

I have a 300m twisted-pair cable connecting 2 video op-amps - which forms a balanced video feed over twisted pair. However, with the cable being coiled, and plugged/unplugged, I am seeing ESD problems which keep blowing the op-amps. I'm baffled by the range of TVS devices.

Being a PAL CBVS signal, I need a low capacitance one, but the Littlefuse range doesn't even appear to specify capacitance in their specs. Any pointers you could give me? I'm hoping it will be in a relatively large SMB package (eg SMB, or 0805 minimum size, if it's in chip form), and have the ability to take repeated ESD strikes over many years. Clamping at 5V or over would, I guess, be suitable. I intend to use the same device for a 5V RS485 twisted-pair data line, also.

Any help would be greatly appreciated.

Cheers,

Neil.
