Frequently Asked Questions
What resistance value and tolerance does the Panasonic ERJ2RKF91R0X provide?
The ERJ2RKF91R0X provides 91 Ω resistance with a precision ±1% tolerance. This tight tolerance ensures predictable voltage divider ratios and current-sense accuracy in analog circuits, making it a reliable choice for feedback networks in DC-DC converters and op-amp biasing where resistance variation above ±1% would degrade circuit performance.
What power rating and operating temperature range does the ERJ2RKF91R0X support in a 0402 package?
The ERJ2RKF91R0X is rated at 0.1 W (100 mW) power dissipation in the 0402 package. The thick-film construction supports an operating temperature range of -55°C to +155°C, allowing use in industrial and automotive auxiliary circuits. At elevated temperatures, power derating applies above 70°C to maintain resistor reliability.
How does the 0402 package size of the ERJ2RKF91R0X benefit high-density PCB designs?
The 0402 package measures 1 mm × 0.5 mm × 0.35 mm height, occupying approximately 0.5 mm² of PCB area per resistor. Compared to 0603 resistors at the same 91 Ω value, the 0402 footprint reduces component area by about 50%, enabling tighter component spacing and supporting 4-layer to 6-layer PCBs with high component density in IoT modules and mobile devices.
Is the ERJ2RKF91R0X RoHS and REACH compliant for use in regulated markets?
Yes, the ERJ2RKF91R0X carries RoHS-compliant and REACH-compliant certifications, with a Pb-free JESD-609 code of e3 confirming lead-free solder compatibility. This makes it suitable for products sold in the EU, Japan, and other regulated markets requiring compliance with hazardous substance restrictions, including consumer electronics and industrial control equipment shipped globally.
