Y007345R4540Q0L Overview

Bulk Metal® Foil Technology Industrial Miniature Precision Resistor with TCR of ± 4 ppm/°C and Tolerance to ± 0.01 %

VRM

Bulk Metal
®
Foil Technology Industrial Miniature Precision
Resistor with TCR of ± 4 ppm/°C and Tolerance to ± 0.01 %
FEATURES
Temperature Coefficient of Resistance:
± 4 ppm/°C (0 °C to + 60 °C);
± 8 ppm/°C (- 55 °C to + 125 °C, 25 °C Ref.)
Resistance Range: 5
Ω
to 50 kΩ
Tolerance: to ± 0.01 %
Power Rating: 0.25 W at + 70 °C; 0.125 W at + 125 °C
Any value at any tolerance available with resistance range
The VRM style is a miniaturized version of the now famous
S102C. It is made with a Bulk Metal
®
Foil element so it
retains all of the inherent performance of foil resistors. It does
not, however, have the value range, power rating, TCR or
lead spacing of the S102C. It is a size for size replacement
for certain wirewounds and finds application in situations
where size constraints dictate the use of this miniature
precision resistor.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.
