60-piece lot of genuine Panasonic ERJ-2RKF1873X precision thick-film surface-mount resistors. These components provide a 187K ohm resistance value with ±1% tolerance in the compact 0402 (1005 metric) package and are rated at 0.10W (1/10W). Panasonic specifies a ±100 ppm/°C temperature coefficient, 50V limiting element voltage, 100V maximum overload voltage, and an operating temperature range of -55°C to +155°C. The ERJ-2RK series is AEC-Q200 Grade 0 qualified and is suitable for precision voltage-divider networks, feedback circuits, bias networks, sensing circuits, power-management designs, automotive electronics, industrial controls, communications equipment, and compact electronic assemblies. Original labeled stock shows Panasonic part number ERJ-2RKF1873X and date code 1732.

HISTORICAL BACKGROUND: Panasonic's ERJ thick-film chip resistor family became a widely used building block as electronics transitioned toward increasingly dense surface-mount construction. The tiny 0402 format allowed designers to reduce PCB area while retaining tightly controlled resistance values and dependable thick-film construction. Precision values such as 187K ohm are particularly useful in feedback dividers, voltage-setting networks, measurement circuits, and bias networks where common rounded resistance values may not provide the desired circuit ratio. The ERJ-2RK family remains representative of the high-volume precision SMD components used across automotive, industrial, communications, and modern power-electronics designs.
