28 AWG Ultra Flexible Silicone Wire

28 AWG silicone wire offers exceptional flexibility for signal and low-power applications through its fine-stranded tinned copper conductor and thin silicone insulation, commonly used in RC models, electronics prototyping, and compact wiring harnesses.

Key features

Ultra-fine flexibility: Typically 16-252 strands of 0.08 mm tinned copper (0.08-0.3 mm² cross-section) for easy routing in tight spaces and solderability.
Tinned strands prevent oxidation, extend lifespan, and simplify soldering or crimping.
Smooth silicone rubber insulation resists acids, alkalis, and maintains pliability over time.

Construction details

Conductor: Tinned copper, e.g., 16/0.08 mm or higher strand count, with ~0.32 mm diameter.
Insulation: Silicone rubber, ~0.08-0.4 mm thick, overall diameter ~1.2 mm for minimal bulk.
Often supplied in lengths like 5 m red + 5 m black for paired signal or power runs.

Electrical performance

Rated voltage: 600V with low resistance (~227 Ω/km) and current up to ~1.25A for signals or lights.
Temperature range: -60°C to +200°C, ideal for high-heat electronics or outdoor use.

Typical applications

RC servos, sensors, LEDs, and model wiring where space and flexibility are critical.
Household appliances, instruments, motor leads, and digital circuits needing durable insulation.
Prototyping, battery tabs, and multi-color hookups in drones or hobby projects.
