Vishay’s NTCS0805E3222JMT Case Resistor

NTCs and other thermosensors traditionally come in through-hole packages. Vishays NTCS0805E3222JMT is an excellent SMD part which can be placed right next to the heat source or ground plane whose temperature value you wish to monitor.

Just as in the case of most other Vishay resistors, the part number NTCS0805E3222JMT stands for but one component in an entire family of values. In our case, particularly, we are looking at 0805 case resistor with a value of 2k2 Ohms at nominal temperature. The whole family is shown in the table contained in the figure.

Vishay provides a wide range of values for this resistor…

The data sheet for the component is relatively limited in that it only explains the deviation of the B values found in the individual parts. However, excellent and wide-ranging further amount of information is available by visiting the curve computation website found at www.vishay.com/thermistors/ntc-curve-list/ and shown in figure two.

The only issue related to the product is that it is – like most other Vishay design tools – based on VBA, and thus requires the presence of a real version of Excel. Nevertheless, Vishay’s part most definitely deserves your attention when looking for NTCs – being able to eliminate annoying and slow throughhole processes is a surefire way to bring and assembly cost down.
