These high resistance precision chip resistors are designed for use
in extremely low signal detection / amplification circuits. Applications
include: Photodiode signal amplification, photomultipliers, ionization
detection, etc. These precision high resistance chip resistors can
also be ideal for use as the input resistor for high impedance voltage
division.
Style FC - Flip Chip version for surface mount applications. This
version has solderable metallized termination pads on one side of the
substrate, the same side as the resistive element. The back side of
the substrate is bare ceramic.
Style WB - Wire Bond versions for hybrid applications are available
on a custom basis for high quantity applications. Contact Applications
Engineering.
Type CHR High Resistance Precision Chip Resistors
Style FC - Flip Chip Version is a surface mount version with solderable pads for flip chip soldering.
Temperature Coefficient:
10 Meg to 25 Meg:
25 ppm/°C -40°C to +85°C, referenced to +25°C.
Above 25 Meg:
35 ppm/°C +10°C to +40°C, referenced to +25°C.
70 ppm/°C -40°C to +85°C, referenced to +25°C.
TC is referenced to +25°C, ΔR taken at low
temperature and high temperature.

Packaging information:
Style FC, flip chip resistors, are shipped with the bare ceramic
side up in the pocket, with the solderable pads facing down.
The illustration shows the orientation of the pocket. The
CHR2520FC is available only with this pocket orientation.
Full reel quantities:
1000 pieces per reel. Quantities of less than 250 will be shipped in
tape without reel and without tape leader at the option of Caddock.
Tape dimensions and materials will be consistent with EIA-481-1.
Reels will be marked with a label containing Caddock logo, part
number, resistor value, tolerance, packaging date, and quantity.
Standard Resistance Values:
Tolerance ±1% Standard.

Solder attachment note:
Style FC has a bare ceramic back
surface. The recommended solders for
flip chip solder attachment are
62Sn/36Pb/2Ag, 96.5Sn/3.5Ag, or
standard Sn/Ag/Cu solder alloys.
Custom resistance values and non-standard
tolerances can be manufactured for high
quantity applications. Please contact
