Focusens MF58 series NTC thermistor is high precision NTC thermistor sealed in glass.
There are two lead type of MF58 thermistor, the radial lead type with ordering code MF58A and MF58B is sealedas small glass bead diameter Max.1.5mm and 2.2mm respectively,the axial lead part MF58C is packed in standard DO35 glass.
This chip in glass thermistor have standard and small size. With advanced ceramic sintering and glass sealing technique it have advantage of high precision, miniture size,fast response and reliable stability especially under 100-250'C high temperature.
The MF58 thermistor is widely used for temperature sensors as well as used directly on PCB or circuit for precision temperature sensing.
