SymbolFootprint3D modelPinsfor all variants
  • ✓Datasheet: replaced the LCSC/JLCPCB copy of YAGEO RT V.16 (May 06, 2025) with YAGEO's current edition, Product specification V.17, February 12, 2026, downloaded 2026-10-27 from yageogroup.com (https://yageogroup.com/component-documentation/download/datasheet/RT0402BRE071K37L?lang=en, the part page's DataSheet link, which serves https://yageogroup.com/content/datasheet/asset/file/PYU-RT_1-TO-0-01_ROHS_L). DigiKey's listing for this part links the same YAGEO URL
  • ✓Part number decoded with 'Ordering information - global part number' (p.2): RT series; 0402 size; B = ±0.1%; R = paper/PE taping reel; E = 50 ppm/°C; 07 = 7-inch reel; 1K37 = 1.37 kΩ (resistance rule table, p.2); L = default code. The YAGEO part-search API returns the same base part with datasheet group PYU-RT_1-TO-0-01_ROHS_L
  • ✓Ratings for RT0402 (Table 2, p.5): 1/16 W at 70 °C, max. working voltage 50 V, max. overload voltage 100 V, operating temperature -55 to +155 °C; the ±50 ppm/°C, ±0.1% range is 4.7 Ω to 500 kΩ, which covers 1.37 kΩ. Packing (Table 3, p.6): 10,000 pcs per 7-inch paper/PE reel
  • ✓Pins: unpolarized two-terminal part; pins 1 and 2 keep empty names, type passive and the library descriptions (the datasheet has no pin table; both terminations are identical, Fig. 5 p.4)
  • ✓Footprint vs Table 1 / Fig. 5 (p.4) for RT0402 (L 1.00±0.10, W 0.50±0.05, bottom termination I2 0.25±0.10, top I1 0.20±0.10 mm): pads 0.54 x 0.64 mm at x = ±0.51 mm (inner edges ±0.24, outer ±0.78 mm) cover both terminations; pad width 0.64 mm exceeds the maximum body width 0.55 mm; pins 1/2 on the long axis
  • •Land pattern: the RT datasheet gives none and refers to YAGEO's separate 'Chip resistors mounting' data sheet (p.6), which was not located on yageogroup.com; footprint kept as the KiCad R_0402_1005Metric land built on Adom boards
  • •3D body 1.00 x 0.50 x 0.35 mm against RT0402 L 1.00±0.10, W 0.50±0.05, H 0.30±0.05 mm (Table 1, p.4): within tolerance, but the 0.35 mm height sits exactly on the upper limit (the KiCad R_0402 model is drawn at the thick-film 0.35 mm height); Z-up, seated on z = 0, centred on the pads
  • ✓Distributors: DigiKey 13-RT0402BRE071K37LTR-ND and Mouser 603-RT0402BRE071K37L kept; both looked up by part number on 2026-10-27 and return YAGEO RT0402BRE071K37L (1.37 kΩ, ±0.1%, ±50 ppm/°C)
  • ✓Symbol and footprint Datasheet properties point at the manufacturer datasheet URL
  • ✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
  • ✓component-page-verify: all checks pass
