Frequently Asked Questions
How does the 1% tolerance of the CR0805-FX-1961ELF benefit precision voltage divider designs?
The CR0805-FX-1961ELF offers a 1% tolerance on its 1.96 kΩ resistance, ensuring that voltage divider ratios remain accurate within tight error budgets in analog circuit designs. This level of precision reduces cumulative error in sensor signal conditioning, ADC reference networks, and feedback loops, making it a reliable choice over standard 5% resistors wherever system accuracy is a design constraint.
What physical dimensions does the CR0805-FX-1961ELF package occupy on a PCB footprint?
The CR0805-FX-1961ELF uses the standard 0805 package measuring approximately 2mm in length and 0.5mm in height, following the EIA 0805 footprint specification. This package size supports automated surface mount assembly with standard 0805 land patterns, balancing ease of soldering and handling with a board area suited for medium-density PCB layouts in industrial and consumer products.
In which industrial applications does the CR0805-FX-1961ELF offer a dependable pull-up resistor solution?
The CR0805-FX-1961ELF at 1.96 kΩ and 1/8W rating serves as an effective pull-up resistor on I2C and SDA/SCL communication lines, open-drain GPIO outputs, and MOSFET gate bias networks in industrial PLCs, sensor nodes, and embedded controllers. Its 1% tolerance ensures consistent logic-level threshold control and prevents signal integrity issues on bus lines operating up to 5V supply voltages in thermally stable environments.
