Summary
every figure cited to the datasheet below- 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 outerp.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 seriesp.3
- Rated 1/10 W (100 mW) at 70 °C, derating linearly to zero at +155 °Cp.1
- Max working voltage 75 V; max overload voltage 150 V; dielectric withstanding voltage 300 Vp.1
- TCR ±100 ppm/°C — the 0603 bracket for R > 10 Ωp.3
- Operating temperature −55 to +155 °Cp.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 MΩp.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 solderingp.3, p.1
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
