Lead (Pb)-Bearing Thick Film,
Rectangular High Value Chip Resistor
FEATURES
• High resistance values (up to 470M)
• Suitable for voltage dividers and hybrids
• Lead (Pb)-bearing termination plating on Ni barrier layer
• Metal glaze on high quality ceramic
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
Notes
• These resistors do not feature a limited lifetime when operated within the limits of rated dissipation, permissible operating voltage, and
permissible film temperature. However, the resistance typically increase due to the resistor’s film temperature over operating time, generally
known as drift. The drift may exceed the stability requirements of an individual application circuit and thereby limits the functional time.
• Marking and packaging: See datasheet “Surface Mount Resistor Marking” (www.vishay.com/doc?20020
)
• Power rating depends on the max. temperature at the solder point, the component placement density and the substrate material.
Note
(1)
The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the
printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 155 °C is not exceeded.
