15 Ω Resistor 0402 - Bourns CR0402-FX-15R0GLF

Bourns CR0402-FX-15R0GLF: 0402 Thick Film Resistor, 15 Ω ±1%, 1/16 W. An Adom Basic Part: Adom keeps it on reels for its pick-and-place line, so boards built with it draw on Adom stock.

Notes for designers

The datasheet’s 1 A current rating applies to the zero-ohm jumper, not this 15 Ω resistor. For this value, enforce both power and voltage limits: at 70 °C the nominal 62.5 mW power bound is about 64.5 mA or 0.968 V, before resistance tolerance and design margin. Reduce allowable power above 70 °C. Bourns CR-series datasheet, electrical characteristics.

CR0402-FX-15R0GLF is the 15 Ω member of Bourns’ CR series of general-purpose thick film chip resistors, in the 0402 size, a 1.00 × 0.50 mm body just 0.32 mm thick, built on a three-layer termination with a nickel barrier under the tin plating. (p.2, p.1) Tolerance is ±1 %, and like every CR0402 the top carries no marking, the value travels in the ordering code (15R0 → 15 Ω, ‘R’ marks the decimal point), not on the part. (p.1, p.5, p.6)

Design against 1/16 W at 70 °C ambient, the rating derates linearly above that and reaches zero at +155 °C (p.1, p.3), and keep continuous voltage at or below 50 V; the 100 V figure is an overload limit, not a working one. (p.1) TCR is ±100 ppm/°C across the 10 Ω-1 MΩ ±1 % band this value sits in. (p.1) At a value this low the 1 A rated current (2.5 A max overload) is the other ceiling to watch. (p.1) A 2.5× rated-voltage, 5-second overload is allowed to shift the value by up to ±(2 % + 0.1 Ω), worth knowing if a transient can land across it. (p.4)

3D model provenance

Bourns publishes no 3D model for the CR series, so the STEP is AI-generated from the Bourns CR Series datasheet (REV. 03/21, p.2 Product Dimensions, CR0402 row) with OpenCascade: L 1.00, W 0.50, T 0.32 mm, top terminal C 0.20 mm, bottom terminal D 0.25 mm, as a white alumina body with a black overcoat between tin-plated wrap-around terminals. The marked STEP carries the part number from the mark planner; CR0402-FX-15R0GLF-unetched.step is the same model without it. The previous model (KiCad's generic R_0402_1005Metric) is kept in provenance/, with the builder in provenance/tools/.

Footprint

Corners: square, as the datasheet draws them. The datasheet does not call for rounded corners, so the footprint does not add any.

Why the pads line up flush with the chip's terminals

Seen from underneath, each pad's inner edge sits exactly on the inner edge of the chip's bottom terminal, the pad is exactly as wide as the chip, and the copper reaches past the chip only at its two outer ends. That is the intended fit, and it follows the land-pattern standard and the Bourns datasheet:

  • IPC-7351B solder-joint goals for chip resistors and capacitors smaller than 0603 (1608 metric), nominal density: toe 0.20 mm, heel 0.00 mm, side 0.00 mm (summarised on the PCB Libraries forum). The toe is the copper beyond the terminal's outer end, where the solder fillet forms and is inspected; heel and side are the copper inside and beside the terminal, and their nominal goal is zero.
  • Bourns CR Series datasheet (REV. 03/21, p.2): CR0402 body L 1.00 +/- 0.05, W 0.50 +/- 0.05, T 0.32 +/- 0.05, bottom terminal D 0.25 +/- 0.10 mm; Recommended Pad Layout a (gap) 0.50 to 0.60, b (overall) 1.40 to 1.60, c (pad width) 0.40 to 0.60 mm.

This footprint uses a 0.50, b 1.50, c 0.50 mm, all inside Bourns' table:

Goal IPC-7351B nominal This footprint From
Toe 0.20 mm 0.25 mm (b - L) / 2 = (1.50 - 1.00) / 2
Heel 0.00 mm 0.00 mm (L / 2 - D) - a / 2 = 0.25 - 0.25
Side 0.00 mm 0.00 mm (c - W) / 2 = (0.50 - 0.50) / 2

In the 3D viewer the part is seated at z = 0, the top of the copper. The pad outlines and the copper fill are drawn 0.02 mm below it so they never flicker against the part, which can read as a hairline gap when you zoom in close.

Chip outline

The part's 3D outline in the standard pose (pad 1 toward the viewer), drawn from the STEP by Adom's OpenCascade service; the part number sits where the laser-etched mark is on the 3D model and reads the same way.

Symbol options

The default symbol, CR0402-FX-15R0GLF.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. CR0402-FX-15R0GLF-outline.kicad_sym is the same symbol with the part's 3D chip outline drawn beside it, its part number placed and reading as on the 3D model.
