HIGH POWER THICK FILM CHIP RESISTOR
TYPE CRGH SERIES I AEC-Q200 QUALIFIED
INTRODUCTION
The resistive element is screen printed and fired, and a passivation
layer added. Each resistor is trimmed to tolerance by laser. The
pre-scribed tile is then broken into strips, the end plating fired on,
and the strips broken into individual components. Final termination
finish is electroplated matte Sn over a Ni barrier layer. This high
power resistor is now AEC-200 Qualified.
FEATURES
•
Thick film resistors with high power to size ratio, ideally suited
to industrial and general purpose use
•
Value range from 1Ω to 10MΩ
•
Seven Package sizes
•
Terminal finish matte Sn over Ni
•
AEC-Q200 Qualified

Notes:
1.
* Rated continuous working voltage (RCWV) shall be determined from RCWV = √(Rated Power x Resistance Value), or Maximum RCWV listed above, whichever is less
2.
**Recommended Circuit Board Design - If this device is anticipated to run at full continuous power then action to improve the cooling should be
taken. This can be a metal substrate, copper pad left under the chip, an opening in the PCB or enlarged silver conductor pads each end.

DERATING CURVE
Resistors shall have a power rating based on continuous load operation at an ambient temperature of 70⁰C. For temperature more
than 70⁰C, the load shall be derated as shown below

VOLTAGE RATING
Resistors shall have a rated direct-current (DC) continuous working voltage or an approximate sine-wave root-mean-square (RMS)
alternating-current (AC) continuous working voltage at commercial-line frequency and waveform corresponding to the power rating,
as determined from the following formula:
RCWV = √P x R
Where:
RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and waveform (volt)
P = Power Rating (watt)
R = Nominal Resistance (ohm)
In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value.
