VFF 300 V 60 °C PVC Flat Flexible Cord

VFF is a PVC-insulated flexible cord manufactured by Xinya Electronic Co., Ltd. It is rated 300 V. The catalogue describes it as a flat / oval section, heat-resistant construction. It is supplied in 4 recorded constructions spanning 0.5–2 mm², with an overall diameter of 2.50 × 5.60 mm to 3.40 × 6.80 mm, cut to the length you order.

How VFF compares with its nearest alternatives

VFF and VSF share the 300 V rating and PVC insulation. Overall diameter is 2.50 × 5.60 mm to 3.40 × 6.80 mm against 2.5–3.4 mm for VSF. Insulation wall is 0.8 mm against 0.72 mm.

VFF and VCTFK share the 300 V rating and PVC insulation. Overall diameter is 2.50 × 5.60 mm to 3.40 × 6.80 mm against 4.30 × 6.60 mm to 5.00 × 8.00 mm for VCTFK. Insulation wall is 0.8 mm against 0.6 mm. Size coverage is 0.5–2 mm² against 0.75–2 mm².

Conductor construction and selection

Every construction listed for VFF is a stranded conductor, which suits harnesses and assemblies that are flexed or routed around a bend. The resistance column gives the maximum permitted value for the conductor at 20 °C DC.

How to read the VFF table

“Insulation O.D. (mm)” is measured over the insulation, not over a jacket, tape or braid. Conductor resistance is stated at 20 °C DC per kilometre — divide by 3.281 for ohms per 1,000 ft.

Questions buyers ask about VFF

Which sizes of VFF are available?

0.5–2 mm², across the 4 constructions in the table below. Sizes outside the table can be quoted on request.

Is VFF a stranded conductor?

Every construction documented for this line is stranded. Confirm the strand count you need — the “n/mm” figure in the table — because resistance and flexibility both depend on it, and two rows at the same size can differ.

What overall diameter does VFF run to?

The documented range is 2.50 × 5.60 mm to 3.40 × 6.80 mm. Quote the size, not the style alone, when the diameter has to fit a specific gland, grommet or channel.
