680 kΩ Resistor 0603 - Royalohm 0603WAF6803T5E

Royalohm 0603WAF6803T5E: 0603 Thick Film Resistor, 680 kΩ ±1%, 1/10 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.

Key specs

Spec Datasheet
0603 thick film chip resistor, 1.60 × 0.80 mm body, 0.45 mm thick, high-purity alumina substrate; three-layer termination: Ni/Cr inner, Ni barrier, lead-free Sn outer p.1
680 kΩ ±1 %, ordering code 6803 = 680 × 103 Ω (1st-3rd digits significant, 4th = zeros); ≤1 % values draw from the E-24 & E-96 series p.3
Rated 1/10 W (100 mW) at 70 °C, derating linearly to zero at +155 °C p.1
Max working voltage 75 V; max overload voltage 150 V; dielectric withstanding voltage 300 V p.1
TCR ±100 ppm/°C, the 0603 bracket for R > 10 Ω p.3
Operating temperature −55 to +155 °C p.1
Short-time overload: ΔR within ±(1.0 % + 0.05 Ω) at ±1 %; load life ΔR within ±(1 % + 0.05 Ω); insulation resistance ≥ 1,000 MΩ p.3
Top marking: E-24 value at ±1 %, marked like a 5 % part (3 digits) but with an underline, the doc’s rule for E-24 values outside E-96 at ≤±1 % p.2
Suffix T5E: tape & reel, 5,000 pcs, lead-free (standard); suitable for both wave and re-flow soldering p.3, p.1

Notes for designers

0603WAF6803T5E is the 680 kΩ member of Royalohm’s (UNI-ROYAL) general-purpose thick film chip resistor line in the 0603 size, a 1.60 × 0.80 mm alumina-substrate body 0.45 mm thick, with a nickel barrier under the lead-free tin termination. (p.1) Tolerance is ±1 %; the ordering code decodes as 6803 = 680 × 103 Ω (1st-3rd digits significant, 4th = zeros), and the T5E suffix means tape & reel, 5,000 pcs, lead-free. (p.3)

Design against 1/10 W (100 mW) at 70 °C, the derating line runs from full load at 70 °C to zero at +155 °C, and keep continuous voltage at or below 75 V; the 150 V figure is an overload limit, not a working one. (p.1) TCR is ±100 ppm/°C, the 0603 bracket for values above 10 Ω. (p.3) A short-time overload is allowed to shift the value by up to ±(1.0 % + 0.05 Ω), and load life by the same, the 0.05 Ω adder matters at the low end of the range. (p.3)

Footprint

The datasheet has no land pattern, so the pads are the IPC-7351 nominal pattern (KiCad's standard Resistor_SMD:R_0603_1608Metric), replacing pads that were off it by up to 0.15 mm.

Source: IPC-7351 nominal (no land pattern in the datasheet): KiCad 10 Resistor_SMD:R_0603_1608Metric pads.

Pad length (along the part) none given 0.8 0.9 0.8
Pad width none given 0.95 1 0.95
Gap between pads none given 0.85 0.7 0.85

Corner radius none given 0.2 (ratio 0.25) 0.225 (ratio 0.25) 0.1 (ratio 0.125)

Corners: KiCad roundrects with the radius held to 0.25 x the smaller pad side and no more than 0.1 mm (IPC-7351C favours rounded corners for paste release); copper area within 1.13 % of a square-cornered pad.

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, 0603WAF6803T5E.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. 0603WAF6803T5E-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.
