OPTIONS:
CODING:
The code number to be ordered may be specified as follows:
NOTE 1: Special tolerances are available on request. Consult factory for special resistance tolerances, non-standard
NOTE 2: The zero-power resistance at 25°C, expressed in Ohms, is identified by a three digit code number. The first two digits
g
Suitable for most low cost temperature measurement,
control or compensation applications
Fast thermal response times
Rugged glass encapsulation provides hermetic seal and
better strain relief than large glass coated bead thermistors
Long term stability is better than large glass coated bead
thermistors
Suitable for self-heated applications such as liquid level
sensing or gas flow measurement
Recommended for all applications where the customer will
perform further assembly operations
Normal operating/storage temperatures range from
-80°C to:
Unaffected by severe environmental exposures, including
nuclear radiation
Intermittent operation up to 600°C is permissible,
however, stability will be degraded.
Non-standard resistance tolerances
Non-standard resistance values
Reference temperature(s) other than 25°C - specify
Mounting in special housings or enclosures
Longer continuous leads
Welded or soldered extension leads - specify lead material, diameter, length and insulation, if any.
Solderable or weldable/solderable leads
Leads can be pre-tinned or treated for improved soldering
Calibration - specify temperature(s)
Interchangeable pairs or set, curve matching - specify temperature range(s) and tolerance(s)
Special aging and conditioning for high reliability applications
BR 55
resistances and/or non-standard temperatures.
represent significant figures, and the last digit specifies the number of zeros to follow. Example: 7.5k Ohms= “752”.
The standard resistance values are from the 24-Value series decade as specified in Military Standard MS90178.
