XH2.54 Red-Black Terminal Wire: Performance Specifications and Applications
Rated Current: Standard continuous current capacity is 3A (AC/DC) at 25°C ambient, with temperature rise ≤30°C and contact resistance ≤20mΩ; peak short-term current can reach 5A (for up to 10 seconds), beyond which plating melting or insulation degradation may occur.
Rated Voltage: 250V AC/DC, with dielectric strength of 1000V AC between terminals, suitable for low-voltage control and signal transmission.
Contact Resistance: ≤20mΩ (tin-plated copper alloy contacts); for high-frequency or high-reliability applications, gold-plated terminals (≤10mΩ) are recommended.
Insulation Resistance: ≥1000MΩ at room temperature (tested at 500V DC); maintains ≥100MΩ under humid-heat conditions (40°C / 95% RH).
Operating Temperature Range: Standard models: -25°C to +85°C; high-temperature variants (e.g., silicone-insulated) can operate up to 200°C.
Wire Gauge & Cross-Section: Common gauges: 22AWG to 20AWG, nominal cross-section: 0.33mm² to 0.52mm², outer diameter: 1.65mm ±0.05mm.
Certifications: Compliant with UL, ROHS, and Chinese National Standards; some models meet FT1 VW-1 flame retardant rating.
Note: Current rating derates with ambient temperature — e.g., 1.8A at 70°C, 1.2A at 85°C.
Industrial Automation: PLC signal interconnects, relay control circuits, inverter wiring, sensor interfaces.
Consumer Electronics: Smart speakers, LED strips, electric toys, security cameras, household appliance internal wiring.
Automotive Electronics: Car audio systems, cooling fan power lines, battery pack connections, lighting control harnesses.
Renewable Energy & Hobbyist Drones: Lithium battery pack leads, solar panel parallel connections, UAV power transmission, ESC wiring.
Electronics Prototyping: PCB-to-PCB connections, sensor module expansion, Arduino/Raspberry Pi power input lines, rapid prototyping bench wiring.
