Q:
Hi, I would like to use these flashing LED's Product code 3538 with a 9V battery and I would like to know what sort of resistor i need for that.
Thank you

Hi there,
I have used our LED Calculator on the link below.
https://www.kitronik.co.uk/blog/led-resistor-value-calculator
Using that I reckon that you will be looking at a 330 Ohm resistor.
All the Best

Q:
I plan to use these flashing LED's in a project I have planned - Product Code: 3538 Red Flashing 5mm Water Clear LED - 30deg - 3500mCd. Can you please advise me if they would run off a standard 3V Coin Cell Battery or would you advise using resistor? If a resistor is required then what value would you advise to work with a 3V Coin Cell Battery. Thanks in advance.
Asked by: doni cameron
A:
These LED’s are fine to be run off a standard 3V coin cell without a resistor.
