WebThe lithium 3.0V button/coin cell batteries BR1225 and CR1225 are widely used in thermometers, dog collars, keyless remotes, PDAs, medical scales, heart rate monitors, remote controls, motherboards, and other electronic equipment. Is it possible to utilize CR1220 as CR1225 battery equivalent? Do you think so? Web13 Mar 2010 · The datasheet of the 24LC256 EEPROM states that:. The SDA bus requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz). I thought that any resistor with a kΩ value would do the job (and it seems that my EEPROM works fine at different frequencies with a 10 kΩ resistor).

Web26 Oct 2024 · 4) A CR2032 can provide only a small current and has a short life-time. If you have space, use bigger battery cells. 5) 3 x CR2032 in series give 9V initially but that will droop. They will drive 2 LEDs in series, at about 20mA, using a series resistor of (9-2 x 3)V/20mA = 150 Ohms.
