300144Z, 300145Z (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Z-Foil Voltage Divider Resistors with TCR

Tracking to 0.1 ppm/°C, Power Coefficient Tracking of 5 ppm

at Rated Power, and Tolerance Match to 0.005 % (50 ppm)

FEATURES

• Temperature coefficient of resistance (TCR):

absolute:

Pb-free

Available

0.05 ppm/°C typical (0 °C to + 60 °C)

0.2 ppm/°C typical (- 55 °C to + 125 °C,

+ 25 °C ref.)

RoHS*

COMPLIANT

tracking: 0.1 ppm/°C typical

• Tolerance: absolute and matching to 0.005 %

• Power coefficient tracking “ΔR due to self heating”: 5 ppm

at rated power

Any value at any tolerance available within resistance range

• Power rating: 0.2 W at 70 °C, for the entire resistive

element R1 and R2, divided proportionally between the

two elements

INTRODUCTION

• Ratio stability: < 0.001 % (10 ppm) 0.2 W at 70 °C for

2000 h

The 300144Z, 300145Z voltage dividers are the first choice

for ultra high precision, stability and reliable voltage division.

• Maximum working voltage: 200 V

• Electrostatic discharge (ESD) above 25 000 V

• Non inductive, non capacitive design

• Rise time: 1 ns without ringing

• Current noise: < - 40 dB

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Non inductive: < 0.08 µH

The Z-foil technology provides a significant reduction of the

resistive component’s sensitivity to ambient temperature

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

0.05 ppm/°C absolute TCR removes errors due to

temperature gradients.

Models 300144Z and 300145Z offer low TCR (both absolute

and tracking), low power coefficient, excellent load life

stability, tight tolerance, excellent ratio stability, low thermal

EMF, low current noise and non sensitivity to ESD - all in one

package.

• Non hot spot design

• Terminal finishes available: lead (Pb)-free

tin/lead alloy

Model 300145Z is a pair-of 300144Z elements back to back

in a single molded package.

• Any value available within resistance range (e.g. 1K2345)

• Prototype samples available from 48 h. For more

information, please contact foil@vishay.com

By taking advantage of the overall stability and reliability of

Vishay Bulk Metal^®foil resistors, designers can significantly

reduce circuit errors and greatly improve overall circuit

performances.
