SMD100/33-2 – TE CONNECTIVITY

The SMD100/33-2, manufactured by TE Connectivity (formerly Raychem Circuit Protection), is a surface-mount resettable fuse, specifically a polymeric positive temperature coefficient (PPTC) thermistor. This device provides overcurrent protection up to its rated hold current, and trips to a high-resistance state when that current is exceeded, limiting the fault current. The “SMD100” indicates a surface-mount device with a specific footprint and profile. The “33” designates a hold current of 3.3A, representing the maximum current the device can carry continuously at a specified ambient temperature (typically 25°C) without tripping. The “-2” likely refers to a specific lot code or minor variant within the SMD100/33 series, potentially indicating a revised trip time or resistance tolerance. The 204147-000 and SMD100/33-2OBS designations likely represent internal TE Connectivity part numbers and an obsolete status, respectively, suggesting the device may no longer be actively manufactured.
