How to Select DC Power Jack by Contact Material and Temperature Resistance

Explain the difference between full copper, semi-copper and gold-plated contacts for DC power jack, and how high temperature resistant housing improves service life for industrial electronics.

Contact material directly decides the conductivity and oxidation resistance of DC power jack. Full copper contacts have excellent electric conductivity, low contact resistance and stable current transmission. Gold-plated DC power jack adds gold coating on copper surface, resisting oxidation effectively even under high humidity environment. Semi-copper DC power jack balances cost and performance, suitable for general consumer electronics without strict corrosion resistance requirements. The plastic housing material is another key factor. High temperature resistant plastic can withstand heat during soldering and continuous working, preventing deformation of DC power jack under long time power load. For high current equipment, users should pick DC power jack with thicker copper contacts. Gold-plated models are recommended for products requiring long service life and frequent plugging. Choosing proper contact material reduces the risk of poor contact caused by oxidation.
