ERJ-2RKF4701X

Panasonic's manufacturer order code is ERJ2RKF4701X; distributors also insert the hyphen shown here. This is a nonpolar 4.7kΩ, ±1%, ±100ppm/K thick-film resistor in 0402 (1005 metric), rated 0.1W at70°C. Above70°C, derate linearly to zero at155°C and keep the case below the upper category temperature. Continuous working voltage is the lower of50V and sqrt(allowable power × resistance). The 100V overload-test ceiling is not a continuous rating. Series AEC-Q200 Grade0 status does not qualify the assembled instrument.

Nominal body is1.00×0.50×0.35mm, each ±0.05mm; top termination length0.20±0.10mm and bottom0.25±0.05mm. This size has no factory value marking. Included STEP/GLB are attributed generic KiCad geometry of the nominal envelope, not manufacturer CAD or a tolerance model; terminal details are approximate. STEP is in millimeters, GLB meters, Z up, seating plane zero. Hero labels are reference artwork and must not be used as assembly geometry.

The manufacturer land guide gives inner gap0.5–0.6mm, total span1.4–1.6mm and width0.4–0.6mm. Included reflow example selects0.55mm gap,1.50mm span and0.50mm width: pad length0.475mm, centers±0.5125mm. Board footprints and solder processes need separate review. Terminals1 and2 are electrically interchangeable.

This reusable component remains provisional. Its identity, two-pin mapping and nominal geometry have been checked; live wiki rendering, native board selection, assembly, temperature and electrical qualification remain separate. It is a candidate, not an adopted electronic-load BOM change.
