Precision Metal-Film Resistors for Low-Cost Uses
Preview
Token offers a low-cost alternative commercial metal film
resistor for precision applications. The MF series offers
tight tolerances and low TCRs over a wide resistance range
and are suitable for applications where long-term stability
is paramount.
The MF is available in a resistance range of 10Ω to 1MΩ
with a standard resistance tolerance of ±1% and a
temperature coefficient of resistance (TCR) of
+15/-25ppm/°C, although other tolerances and TCR
s are available.
The resistance element in these devices is a precisely
controlled thin film of metal alloy deposited on a high
quality alumina rod. Plated caps are force-fitted before the assembly is trimmed using advanced trimming
techniques to ensure excellent performance and low electrical noise.
Leads are welded to the end caps prior to the resistor being coated with epoxy, and colour band marking applied.
A variety of standard lead forms are available for use where auto-insertion is not available or practical. This gives
the advantage of the value being shown, even if the resistor is machine preformed or auto-inserted.
The MF is RoHS compliant with 100% lead free, Contact us with your specific needs.
Features
- Low cost, low noise, operating temperature range -55°C ~ 155°C
- Precision tighted tolerance available in ±0.1%, ±0.25%, ±0.5%, ±1%
- Pure tin plating provides compatibility with lead (Pb)-free and lead containing soldering processes
Applications
- Telecom
- Test and measurement
- All general purpose applications
