Summary
every figure cited to the datasheet below- 0402 automotive thick film chip resistor (CQ02) — 1.00 × 0.50 mm body, 0.35 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
- 1.5 Ω ±1 % — ordering code 150K = 150 × 10−2 Ω (letter multiplier K = 10−2)p.2
- Rated 1/16 W (62.5 mW) at 70 °C, derating linearly to zero at +155 °Cp.1
- Max working voltage 50 V; max overload voltage 100 V; dielectric withstanding voltage 100 Vp.1
- TCR ±200 ppm/°C — the CQ02–CQ12 bracket for 1 Ω ≤ R ≤ 10 Ω (MIL-STD-202 Method 304)p.2
- 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 TCE: tape & reel, 10,000 pcs, lead-free (standard)p.2
CQ02WGF150KTCE is the 1.5 Ω member of Royalohm’s (UNI-ROYAL) CQ automotive thick film chip resistor series in the 0402 size (CQ02) — a 1.00 × 0.50 mm body 0.35 mm thick, with a nickel barrier under the lead-free tin termination.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 Tolerance is ±1 %; the ordering code decodes as 150K = 150 × 10−2 Ω (letter multiplier K = 10−2), and TCE means tape & reel, 10,000 pcs, lead-free.p.2
Design against 1/16 W (62.5 mW) at 70 °C — derating runs linearly to zero at +155 °C — and keep continuous voltage at or below 50 V; 100 V is the overload limit, not a working figure.p.1 TCR is ±200 ppm/°C per the CQ02–CQ12 1–10 Ω bracket.p.2 Under the AEC-Q200-referenced stresses the allowed drift is tight: ±(1.0 % + 0.05 Ω) after short-time overload or 1,000 h biased humidity, ±(1.0 % + 0.1 Ω) after 1,000 h operational life at 125 °C.p.2
