Panasonic ERJ-2RKF4022X 40.2k Ohm 1% 1/10W 0402 SMD Resistors 80 Pieces
$7.95
Lot of 80 Panasonic ERJ-2RKF4022X precision thick-film surface-mount chip resistors supplied in an original Mouser distributor-labeled packet. Each resistor provides a 40.2k-ohm resistance value, ±1% tolerance, 0.1-watt or 1/10-watt power rating, and ±100 ppm/°C temperature coefficient.
These miniature resistors use the 0402-inch or 1005-metric package and measure approximately 1.0mm × 0.5mm with a maximum seated height of 0.4mm. Operating temperature range is -55°C to +155°C. AEC-Q200 qualified and suitable for automated surface-mount assembly.
Typical applications include voltage dividers, feedback networks, signal conditioning, communications equipment, automotive electronics, industrial controls, test equipment, consumer electronics, prototyping, and component-level PCB repair.
Historical Note: Panasonic’s ERJ family is a long-established line of thick-film chip resistors developed for compact, high-density surface-mount electronics. Standardized package sizes and broad resistance-value coverage have made ERJ components widely used in automotive, industrial, communications, and consumer electronic assemblies.
