Applications

The CRB 0805-HT high temperature, non-magnetic, trimmable chip resistor series from SRT Resistor Technology offers the same features as the CRB 0805 range, while allowing for high temperature applications of up to 300°C. The main features comprise of a resistance range from 1Ω up to 10MΩ, power rating of 0.125W and voltage rating of 100V trimmed or 300V untrimmed (trimming ratios 1.5/single cut), all in a small 0805 package. By utilising SRT’s thick film resistor technology, they are able to offer low tolerances down to ±5.0% and TCR as low as ±50 ppm/°C (between 10Ω and 10MΩ). The CRB 0805-HT resistor series is suitable for laser and air-abrasive trimming, and offers PtAg (Platinum-Silver), unpassivated contact areas suitable for soldering and conductive gluing. These resistors contain no organics, making them suitable for high vacuum applications.

Non-symmetric tolerances are also available (e.g. -0/+20%), please contact us for more information.

Please see the derating curve below for the CHx-HT, CRB-HT and CBW-HT series from 0°C to +300°C:

The final measuring of the resistors takes place at room temperature (independent of TCR).

Please pay attention to the interconnection technology at high temperature applications.

Please note, the tolerance for the CRB 0805-HT series starts from ±5%, whereas the below table gives the full specifications of the standard CRB series:
