FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does the lowercase 'd' suffix mean in FLRYWd?
In German automotive wire nomenclature, lowercase 'd' stands for dünnwandig (extra-thin wall, corresponding to ISO 6722-1 Ultra-Thin-Wall with 0.20 mm nominal / 0.16 mm minimum wall thickness), reducing wire outer diameter below regular reduced-wall ('R') FLRYW.
How much smaller is FLRYWd compared with standard FLRYW?
At 0.35 mm², FLRYWd has a maximum OD of 1.20 mm versus 1.30–1.40 mm on FLRYW. At 0.50 mm², FLRYWd drops to 1.40 mm max OD versus 1.60 mm on FLRYW, and at 0.75 mm² it drops to 1.65 mm versus 1.90 mm.
How does FLRYWd compare with Japanese CIVUS wire?
Both use a 0.20 mm nominal / 0.16 mm minimum ultra-thin PVC wall for high-density ECU connectors. Standard CIVUS is rated to +85 °C (with +105 °C CIVUS-B option), whereas FLRYWd is rated to ISO 6722-1 Class C (+125 °C continuous).
Does FLRYWd require concentric (Type A) or compressed conductors?
Yes. Because the minimum wall is only 0.16 mm, asymmetrical bunched stranding could create high spots that thin the wall locally; FLRYWd therefore uses symmetrical 7/19-wire concentric or die-compressed conductors.
