What the 7 A hold current means for your board
The 1206L700SLPR is a Polymeric PTC resettable fuse from the PolySwitch® 1206L series, rated for a 7 A hold current at 6 V max. This means the device will pass 7 A continuously without tripping — you size the trace and load to stay below this threshold during normal operation. When a fault drives current above 14 A (the trip current), the PTC heats up and its resistance jumps to a post-trip maximum of 7 mOhms, limiting the fault to less than 50 A (the device's maximum interrupt rating). The trip time is 2 seconds typical at 25 °C — fast enough to protect downstream components from sustained overcurrent without nuisance tripping on short inrush pulses.
The concave termination style suits standard reflow soldering profiles for lead-free assemblies.
Active lifecycle and compliance
Production status is Active (Littelfuse continues to manufacture this order code). Carries cURus, TUV, and UL approvals — the relevant safety-agency marks for North American and European equipment certification.
