Panasonic ERJ-2RKF4871X 4.87K ohm 1% 1/10W 0402 Thick Film Resistor 80 PCS PACK

Original Mouser Electronics distributor package containing approximately 80 Panasonic ERJ-2RKF4871X 4.87K ohm ±1% thick-film SMD resistors.

These are compact 0402 / 1005 metric chip resistors rated at 0.1W (1/10W). Panasonic's ERJ-2RK series is designed for high-reliability surface-mount applications and carries AEC-Q200 automotive qualification.

This listing is for ONE sealed/retained distributor package containing 80 pieces. Quantity 1 purchases the complete 80-piece package.

Original Mouser label identifies Panasonic part ERJ-2RKF4871X, Mouser part number 667-ERJ-2RKF4871X, country of origin China, lot code 10327BAK04, and date code 2112.

HISTORICAL BACKGROUND:
Panasonic's ERJ family represents a long-running generation of miniature thick-film chip resistors developed as electronics manufacturing shifted heavily toward automated surface-mount assembly. The ERJ-2RK series uses the 0402 package, allowing substantial component density in compact electronic assemblies while maintaining stable resistance characteristics.

The 4.87K ohm value is part of the precision 1% resistance series commonly used in bias networks, feedback circuits, voltage dividers, sensing networks, control electronics, communications equipment, automotive electronics, and general digital or analog circuitry.

Unlike obsolete vintage components frequently found at RF Boneyard, ERJ-2RKF4871X remains an active-production Panasonic Industry part. This package is older distributor stock preserved in its original Mouser-labeled packaging.
