Bourns CRM-Q, CRS-Q, CMP-Q and CHP-Q series chip resistors

Bourns resistor product line continues to broaden its portfolio of high power, surface mount thick film chip resistors by introducing the new model CRM-Q, CRS-Q, CMP-Q and CHP-Q series thick film chip resistors. These new Q-series models are AEC-Q200 compliant or automotive grade versions of Bourns’ existing model CRM, CRS, CMP, and CHP series thick film chip resistors. The following table shows the differences between the standard thick film chip resistor series, the existing -A series, and the new -Q series.

• These resistors are manufactured using a thick film element printed onto a ceramic substrate. They offer high reliability and are suitable for use in consumer electronics, industrial automation, power supplies, LED lighting applications and communication base stations. The high rated power and superior pulse load capability make them ideal for current limiters and snubber circuits, as well as balancing and bleeder resistors. 
• The Bourns® model CRM-Q series high power resistors and the model CRS-Q series anti-surge resistors are available in three sizes from 1206 (3116metric) to 2512 (6432metric) with rated power from 0.5watts to 2watts.
• The model CMP-Q series pulse power resistors are available in five sizes from 0603 (1608metric) to 2512 (6432metric) with rated power from 0.25watts to 1.5watts.
• The model CHP-Q series ultra-high power resistors relative to size are available in three sizes from 0603 (1608metric) to 1206 (3116metric) with rated power from 0.33watts to 0.75watts.

These resistors feature a wide resistance range from 1ohm to 1megohm, ±1% or ±5% resistance tolerances and a TCR (Temperature Coefficient of Resistance) of ±100 ppm/°C and ±200ppm/°C.
