Summary
every figure cited to the datasheet below- 0603 automotive thick film chip resistor (CQ03) — 1.60 × 0.80 mm body, 0.45 mm thick, alumina substrate; Ni/Cr inner, Ni-barrier, lead-free Sn outer terminationp.1
- Automotive grade: the doc states it “complies with the relevant provisions of AEC-Q200”, and its qualification rows reference AEC-Q200 TEST 1/7/8/15/18/21p.1, p.2
- 0 Ω jumper (ordering code 0000) — resistance <50 mΩ, rated current 1 A, max overload current 2 Ap.1, p.2
- 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
- Anti-sulfurized construction — tested H2S 3–5 ppm, 50 °C, 91–93 %RH, 1,000 h: ΔR at ±1 % within ±(1.0 % + 0.1 Ω)p.1, p.2
- Operational life 1,000 h at 125 °C (AEC-Q200 TEST 8): ΔR within ±(1.0 % + 0.1 Ω); biased humidity 1,000 h 85 °C/85 %RH: within ±(1.0 % + 0.05 Ω)p.2
- Operating temperature −55 to +155 °C; RoHS compliant, suitable for reflow & wave solderingp.1
- Suffix T5E: tape & reel, 5,000 pcs, lead-free (standard)p.2
CQ03WAF0000T5E is the 0 Ω jumper of Royalohm’s (UNI-ROYAL) CQ automotive thick film series in the 0603 size (CQ03) — a 1.60 × 0.80 mm body 0.45 mm thick.p.1 It is the automotive (CQ) series: the doc claims compliance with the relevant provisions of AEC-Q200 and backs it with AEC-Q200-referenced test rows, plus an anti-sulfurized construction proven over 1,000 h in 3–5 ppm H2S.p.1, p.2 The T5E suffix means tape & reel, 5,000 pcs, lead-free.p.2
Design against the current limits, not a resistance: the jumper is specified at <50 mΩ with a rated current of 1 A and a max overload current of 2 A.p.1 The doc defines no TCR for the jumper — its TCR brackets start at 1 Ω.p.2 Ambient limits match the rest of the series: −55 to +155 °C.p.1
