Available in both Tape & Box (TB) and Cut Tape (CT) formats, the TB option ships as a full reel for automated insertion, while CT suits prototype or low-volume builds where only a few pieces are needed.","metaTitle":"LM19CIZ/LFT4 Analog Temperature Sensor, -55 to 130°C, TO-92","metaDescription":"Active-production analog local temp sensor, -55°C to 130°C range, 11.77 mV/°C slope, TO-92 package, 2.4-5.5 V supply.

At 25°C the typical output is about 0.6 V, and it decreases with rising temperature — the slope is negative, so the ADC must be configured for an inverting transfer function."},{"question":"What package does LM19CIZ/LFT4 come in?","answer":"It is supplied in a TO-92-3 through-hole package, also designated TO-226AA. The supplier device package is TO-92.

No REACH, UL, or IEC certifications are listed in the record.
