INTRODUCTION

The Z-foil technology provides a significant reduction of

the resistive component’s sensitivity to ambient temperature

variations (TCR) and applied power changes (PCR).

Designers can now guarantee a high degree of stability

and accuracy in fixed-resistor applications using solutions

based on Vishay‘s revolutionary Z-foil technology.

0.05 ppm/°C absolute TCR removes errors due to

temperature gradients.

Models 303119Z and 303119 are surface mount chip

resistors designed with 4 pads for Kelvin connection.

Utilizing Vishay’s Bulk Metal

Z-foil as the resistance

element, 303119Z provides performance capabilities far

greater than other resistor technologies can supply in a

product of comparable size.

These small devices dissipate heat almost entirely through

the pads so surface mount users are encouraged to be

generous with the board’s pads and traces. Gold

terminations are available as well.

Our application engineering department is available to

advise and to make recommendations.

•

Vishay Foil resistors are not restricted to standard values,

specific “as required” values can be supplied at no extra

cost or delivery (e.g. 1.234

vs. 1

Ω)

•

Tolerance: to ± 0.5 %

•

Power coefficient “ΔR due to self heating”: 5 ppm at rated

power

•

Load life stability: 0.05 % at 70 °C, 2000 h at rated power

•

Electrostatic discharge (ESD) up to 25 000 V

•

Short time overload < 0.02 %

•

Power rating: 0.5 W at + 70 °C (figure 1)

•

Non inductive, non capacitive design

•

Rise time: 1 ns effectively no ringing

•

Current rating: 5 A maximum

•

Current noise: < - 40 dB

•

Voltage coefficient: < 0.1 ppm/V

•

Non inductive: < 0.08 µH

•

Non hot spot design

•

For prototypes units, append a “U” to the model number

(example: 303119ZU). These units have all of the table 2A

(page 3) 100 % tests performed, with no destructive

qualification testing required (table 3A, page 3). For more
