NOTE 1: Special tolerances are available upon 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

DESCRIPTION:

Small glass encapsulated bead thermistors on fine

diameter alloy lead-wires.

FEATURES:

•

OPTIONS:

•

CODING:

The code number to be ordered may be specified as follows:

BR 16

Suitable for most low cost temperature measure-

ment, control or compensation applications

Very fast thermal response times

Rugged glass encapsulation provides hermetic seal

and better strain relief than small glass coated bead

thermistors

Long term stability is better than small 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 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 sets, R-vs-T curve matching – specify temperature range(s) and tolerance(s)

Special aging and conditioning for high reliability applications

represent significant figures, and the last digit specifies the number of zeros to follow. Example: 22k Ohms= “223”.

The standard resistance values are from the 24-Value series decade as specified in Military Standard MS90178.

105°C for Material system E0

200°C for Material systems A1 through A4

300°C for Material systems A5 through D17
