Vishay Foil Resistors

Bulk Metal^®Foil Technology

Discrete High Precision Surface Mount Chip Resistor

FEATURES

• High Precision: Tolerance to ± 0.01% (see table 1)

• Low Temperature Coefficient of Resistance:

Nominal TCR: + 0.5ppm/°C (- 55°C to + 125°C)

• Resistance Range: 10Ω to 30KΩ

Product may not

be to scale

• Load Life Stability: ± 0.01% maximum ∆R under full

rated power at + 70°C for 2000 hours.

• Shelf Life Stability: 50ppm/year (0.005%) maximum ∆R

non-hermetically sealed

• Power Rating at + 70°C: 125mW

• Maximum Working Voltage: 61V

• Maximum Weight: 11mg

The VSM1206 Precision Surface Mount Chip Resistor utilizes

Ultra Precision Bulk Metal^®Z Foil (BMZF) for the resistive

element.

• Voltage Coefficient: < 0.00001%/volt (< 0.1ppm/V)

• Current Noise: < 0.01µV(rms)/volt of applied voltage

• Non Inductive: < 0.08nH

The BMZF technology provides inherently an extremely low

and predictable Temperature Coefficient of Resistance

(TCR), remarkable load life stability, low noise and availability

of tight tolerance.

TCR**

The TCR is a process capability not a selection process and

for most of the range is independent of ohmic value and lot

related variations. The TCR curve on Fig. 1 demonstrates

the new revolutionary Z Foil with its TCR nominal of

0.5ppm/°C.

A voltage divider can be fashioned by using two arbitrarily

selected VSM1206s with a resultant tracking specification

of < 3ppm/°C. Extremely low tracking of < 1ppm/°C can be

supplied upon request.

*Tighter tolerances are available. Please contact Vishay Application Engineering.

The VSM1206 has a conventional full wrap around robust

termination which insures safe handling during manufacturing

process, as well as providing stability during the multiple

thermal cyclings it will see over its service life.

The availability of tight absolute tolerance provides a good

cost solution for the variability of other components when

compiling the total error budget. BMZF offers the best

stability available; and is more than an order of magnitude

better than thin film technology. The noise generated by

the resistor is non measurable and its design and

construction make it well suited for high frequency

applications. The BMZF is the ultimate resistor component

for analog applications.

The TCR for values < 100Ω are influenced by the termination

composition and result in a deviation from this curve.
