Cement Resistors - SQP, SQM, SQT, SQH, SQZ Series
Low-cost Ceramic Cased Resistors
Suit High Volumes and High Temperatures
Preview
Token electronics offers commercial grade ceramic-housed power wirewound and film resistors. For medium to
high rated power (2W...50W), SQ resistors provide full electrical insulation mounted in a ceramic case.
Axial, radial, vertical styles and several mounting techniques of wire leads or quick disconnects are available
from Token’s SQP, SQM, SQZ, and SQH.
The SQ series power resistors feature ideal specifications for high volume and high-temperature applications.
Frequently used in power supplies, motor controllers, and automotive applications, these products can be custom
tailored to individual needs.
With the extended resistance range and high-temperature rating, the resistors can be specified for operation in
harsh environments. The SQ series wirewound resistors feature a resistance range from 0.1Ω to 3KΩ, while the
SQ series power film resistors have a resistance range of 80Ω to 150KΩ.
Standard tolerances for both devices are to ±5%, with TCRs of ±300ppm/°C and above. Token is equipped to
design and produce custom components to meet many design and reliability demands. Contact us with your
specific needs.
