BWW Precision Wirewound Resistors
(BWW) Precision Wirewound Power Resistors
Operate in Harsh Environments
Preview
The new BWW series moulded axial leaded wirewound resistors from Token use high-purity alumina ceramic
cores with wire winding which are spot welded by precision CNC machine tools to ensure total operational
consistency throughout.
Also, using advanced encapsulation die/mould technologies, this precision power resistors are encapsulated with
epoxy molding compound.
The BWW models possess a wide resistance value from 0.1Ω to 39KΩ and meets the stringent requirements of
MIL-R-93. Ayrton Perry noninductive windings are available on request. The BWW precision version has low
ohmic values for current sensing applications.
All versions are miniaturised for better power to dimension ratios and are available in 0.5W to 10W rated power
at 25°C. Tolerance is available in ±0.1%, ±0.25%, ±0.5%, ±1% and ±2% with TCR ±25PPM/°C, ±50PPM/°C
and ±150PPM/°C which makes them ideally suited for use in precision applications.
The BWW series is RoHS compliant with 100% Sn (lead free) coated terminals. To address your need for
technical and economic success in a timely manner, our custom solutions are the best option. Contact us with
your specific needs.
