470 Ω Resistor 0603 - Royalohm 0603WAF4700T5E
Royalohm 0603WAF4700T5E: 0603 Thick Film Resistor, 470 Ω ±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 |
| 470 Ω ±1 %, ordering code 4700 = 470 × 100 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
0603WAF4700T5E is the 470 Ω 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 4700 = 470 × 100 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.
| mm | Datasheet | KiCad standard (R_0603_1608Metric) | Previous | This page |
|---|---|---|---|---|
| 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 |
| Centre to centre | none given | 1.65 | 1.6 | 1.65 |
| Overall | none given | 2.45 | 2.5 | 2.45 |
| 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, 0603WAF4700T5E.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. 0603WAF4700T5E-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.
