Devices Combine Advanced Sulfur Resistance With High Power Ratings to 2.0 W for Automotive and Industrial Applications

Vishay Intertechnology has released a new series of sulfur-resistant long side termination thick film chip resistors optimized for automotive and industrial applications.

For high sulfur environments, resistors in the AEC-Q200-qualified Vishay Intertechnology Draloric RCALS e3 series feature:

A patented construction that provides sulfur withstands ability in accordance with ASTM B80995, tested at an advanced level of 90 °C for 1,000 hours. The devices’ wide terminals enable high power ratings up to 2.0 W.
RCA-LS e3 series resistors are available in five compact case sizes to save space on densely packed PCBs: 0406, 0612, 1020, 1218, and 1225.
The devices offer a resistance range from 1 Ω up to 2.2 MΩ with tolerances of ± 1 % and ± 5 %, TCR of ± 100 ppm/K and ± 200 ppm/K, and an operating voltage range from 50 V to 200 V.
The resistors are RoHS-compliant and halogen-free.

Device Specification Table:

Part #	Case size	Power rating P₇₀ (W)	Operating voltage (V)
RCA0406-LS e3	0406	0.25	50
RCA0612-LS e3	0612	0.5	75
RCA1020-LS e3	1020	1.0	200
RCA1218-LS e3	1218	1.0	200
RCA1225-LS e3	1225	2.0⁽¹⁾	200
⁽¹⁾ Specified power rating requires dedicated mounting conditions to achieve the required thermal resistance.
