Datasheet p.1 Electrical Characteristics

Current, power and voltage

Bourns gives the maximum working current as (P / R)^1/2 (p.1): with P = 3 W and R = 1 mOhm that is 54.8 A at an ambient up to 70 C, falling to zero at 170 C along the derating curve (p.2). At 54.8 A the voltage across the part is 54.8 mV. Power is I^2 x R: 10 A dissipates 0.1 W, 30 A 0.9 W, 50 A 2.5 W. The 1 % tolerance and the +/-50 ppm/C temperature coefficient set the measurement error; the inductance (under 5 nH) and thermal EMF (under 3 uV/C) are small enough for switching-current sensing. How much of the rating a design can use depends on the copper and airflow around the part.

Pins

Pin Function
1 terminal (non-polar)
2 terminal (non-polar)

A resistor has no polarity: either terminal may face either way. For accurate sensing take the two sense traces from the inner edge of each pad, as Bourns' pad layout drawing shows (next section).

Land pattern: Bourns layout, not KiCad's generic 2512

Land pattern
    Land pattern    
The footprint uses Bourns' recommended pads, 3.1 x 4.0 mm with a 1.3 mm gap, because KiCad's IPC 2512 pads (1.225 x 3.35 mm, 4.7 mm gap) would leave most of each 2 mm terminal off the copper. The guide lays both over the part at true scale and explains where the sense traces leave the pads.

The comparison, with the numbers

Marking

Bourns prints the value code R001 on the overcoat of CRE2512-R001 ~ R004 parts, reading across the short axis (p.1, Typical Part Marking). The marked model shows it there.

Datasheet p.1 construction and marking

3D model

No Bourns STEP for this part could be downloaded by plain HTTP: bourns.com refuses non-browser requests (HTTP 403) and the datasheet links no CAD file. KiCad's library model R_2512_6332Metric.step was checked first and does not fit this part: it is 0.60 mm thick with 0.54 mm terminals, while the CRE2512-R001 drawing gives T 0.90 +/-0.20 mm and C 2.00 +/-0.20 mm (check). The model on this page is therefore built from the datasheet by provenance/tools/make_step.py: a 6.40 x 3.20 x 0.90 mm part with 2.00 mm Ni/Sn terminations wrapping each end, the Mn/Cu plate between them and a black overcoat on top and bottom. Every printed dimension is used as printed; the overcoat thickness (0.15 mm) and the underside overcoat are not dimensioned by Bourns and are read from the p.2 side view. A display copy CRE2512-FZ-R001E-3-marked.step adds the marking R001 as its own solid group 5 um above the overcoat; the unmarked STEP is the board CAD file.

The page viewer shows cre2512-fz-r001e-3-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 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 6.400 mm (datasheet 6.20 to 6.60), W 3.200 mm (datasheet 3.00 to 3.40), T/H 0.900 mm (datasheet 0.70 to 1.10), C (terminal, top) 2.000 mm (datasheet 1.80 to 2.20), C (terminal, bottom) 2.000 mm (datasheet 1.80 to 2.20). 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. The marking R001 shows in high and medium and is left out of low and super-low. Previews are rendered from each GLB.
