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 CHARACTERISTICS – ELECTRICAL Type Power Rating (W) @70°C 0402 0603 0805 1206 1210 2010 2512 0.1 0.2 0.33 0.5 0.75 1 2 Resistance Range E24 Standard Values E96 by negotiation 1Ω ~ 10MΩ Tolerance 1% ~ 5% Max.

This can be a metal substrate, copper pad left under the chip, an opening in the PCB or enlarged silver conductor pads each end. High Power Thick Film Chip Resistor Type CRGH Series I AEC-Q200 Qualified 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 Percent rated load (%) -550C 100 +700C +1550C 80 60 40 20 -60 -40 -20 0 20 40 60 80 100 120 140 160 180 Ambient Temperature (OC) 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.
