Vishay Foil Resistors

Models # 303119Z and 303119 (Current Sensing Fixed Foil Resistor Chips

VCS1625Z/VCS1625 Configuration) Screen/Test Flow in Compliance with

EEE-INST-002, (Tables 2A and 3A, Film/Foil, Level 1) and MIL-PRF-55342

FEATURES

• Temperature coefficient of resistance (TCR):

0.05 ppm/°C typical (0 °C to + 60 °C)

0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)

(see table 1)

• Resistance range: 0.01 Ω to 10 Ω

• 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 Ω vs. 1 Ω)

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.

• 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 %

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.

• 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

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.

• Current noise: < - 40 dB

• Voltage coefficient: < 0.1 ppm/V

• Non inductive: < 0.08 µH

Our application engineering department is available to

advise and to make recommendations.

• 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

information, please contact foil@vishay.com
