RC0402FR-0733KL

YAGEO RC0402FR-0733KL: Thick film chip resistor 33 kOhm +/-1 %, 1/16 W, 50 V, 0402 (1005 metric). A general purpose thick film chip resistor from YAGEO's RC_L series.

Key specifications

All page numbers refer to the datasheet PDF in docs/.

Voltage rating

YAGEO rates the continuous working voltage as sqrt(P x R) or the maximum working voltage, whichever is less (p.7). For this value power governs: sqrt(P x R) = sqrt(0.0625 W x 33 kOhm) = 45.4 V continuous, below the 0402 size's 50 V maximum working voltage. The maximum overload voltage is 100 V; the short time overload test applies 100 V for 5 s (p.9).

Notes

• Mouser lists the part as 'RoHS Compliant By Exemption'; the datasheet (p.2) says Pb-glass in electrodes, resistor element and glass is exempted.

Ordering

Stock figures are a snapshot from the Adom parts search on 2026-10-21; check the distributor before ordering. Packaging code R with reel code 07 is a 7 inch paper tape reel of 10,000 pieces (p.7 Table 4).

Manufacturer and resources

Pins

A resistor has no polarity and no pin 1 orientation: either terminal may face either way.

Marking

YAGEO does not mark RC0402 parts (p.3, Fig. 1): the top coat is plain.

Land pattern: KiCad footprint vs YAGEO

Land pattern

The footprint is KiCad's standard `R_0402_1005Metric`, and this guide lays its pads over YAGEO's recommended reflow land, at true scale. It matches YAGEO closely. Use it to decide whether to keep the KiCad pads or change them to YAGEO's numbers before layout. The comparison, with the numbers

3D model

No YAGEO STEP for this exact part number could be downloaded by plain HTTP: YAGEO's product pages build their CAD links in the browser and expose no direct STEP link. The page therefore uses KiCad's library model for the package, R_0402_1005Metric.step, with its bytes unchanged, renamed RC0402FR-0733KL.step, after checking it against the datasheet table (next section). The part is unmarked, so the model shows a plain top coat.

The page viewer shows rc0402fr-0733kl-hero.glb: the clean model plus nonphysical reference artwork drawn under it to the adom-hero standard (adom/component-hero): the footprint's pads as teal dashed outlines at 50 % opacity, its silkscreen at 70 % transparency and the pad numbers 1 and 2 (the terminals have no names). The part is non-polar, so no pin-1 dot is added. The artwork never goes into the STEP, package-reference.glb or the board LODs.

Model checked against the datasheet

The KiCad model was rendered in orthographic top, bottom, side and end views at true scale and laid over a drawing made at the same scale from the printed table (nominal outline, tolerance limits, allowed terminal band). Every dimension is inside the printed range: L 1.000 mm (datasheet 0.95 to 1.05), W 0.500 mm (datasheet 0.45 to 0.55), T/H 0.350 mm (datasheet 0.30 to 0.40), I1 (terminal on top) 0.165 mm (datasheet 0.10 to 0.30), I2 (terminal on bottom) 0.165 mm (datasheet 0.15 to 0.35). The model is Z-up, seated on z = 0, centred on the footprint origin, long axis on X.

Board levels of detail

Clean board-use GLBs (no footprint pads, outlines, labels or silkscreen) in four levels, all in the same Z-up, metre, footprint-origin pose as the STEP. Previews are rendered from each GLB.
