Molex Pin Header, Nylon Body, Tin-Plated Brass Contacts - KK 254 Series - 22-27-2041


To put your circuit board in communication with system components, reach for this pin header from Molex. Simply solder it onto your PCB and its four contacts offer multiple connection points. To ensure optimal conductivity, its pins come with low-resistance tin plating. The non-conductive nylon body protects you against electric shocks, and this plastic is also low-halogen, so it emits minimal toxic fumes if it gets hot.

Features & Benefits


• Flame-retardant, so is unlikely to contribute towards a fire
• Friction locks to mated part for reliable use in vibrating conditions
• Polarised to reduce the risk of incorrect connections

Applications


• Electrical engineering
• Power utilities
• Consumer electronics
• Healthcare facilities

What's the current rating of this pin header?
