Coin Cell Led Resistor at Cameron Malone blog

Coin Cell Led Resistor. I need a cheap way to take a 3v nominal coin cell and power a 3.3 forward voltage blue led. I want to power an led that has a 3.3v forward voltage using two 3v cr2032 coin cell batteries to create a 6v supply. Coin cells exhibit internal resistance — they can only push so much current, it’s the inherent nature of their size and chemistry. So yes, they can run an led directly… but.this. It's true, you can hook up an led directly to a 3.0 volt lithium coin cell, and it will work without burning up. The coin cell battery can be modeled as an ideal 3v power supply with a series resistance or an output impedance (rs). It needs to be cheap in production on a large scale, so a rudimentary joule theif won't. I set the resistor for a 20. The main reason you can get away with this is that a lithium coin cell has a certain. If your battery can only deliver 13ma (max),.

Blue LED Dies Rapidly on 9v Battery but OK on CR2032 Lithium Coin Cell
