The Key Applications:
- Current sensing and shunt applications in dc-to-dc converters,
power supplies, motor circuits,
computers, and cell phones
The News:
Vishay Releases a New High-Reliability, Thick
Film Resistor With Extremely Low Resistance Down to 10 mΩ, Tight
Tolerances of ±1 % and ±5 %, and Low TCR Down to ±100
ppm/K
Vishay Intertechnology, Inc. (NYSE: VSH) announces a
new thick film resistor that combines an extremely low resistance with
tight tolerances and low TCR for current-sensing applications.
- Offered in 0603, 0805, and 1206 case sizes
- Features a special metal glaze on high-quality ceramic with a
protective overglaze
- Lead (Pb)-free solder contacts on a nickel barrier layer, with pure
tin plating providing compatibility with both lead (Pb)-free and
lead-containing soldering processes
Key Device Specifications:
- Resistance range from 10 mΩ to 100 mΩ
- Tolerances of ±1 % and ±5 %
- Three case sizes and power ratings:
| Case Size |
Power Rating |
| 0603 |
0.100 W |
| 0805 |
0.125 W |
| 1206 |
0.250 W |
- TCR of ±100 ppm/K, ±200 ppm/K, ±300 ppm/K, ±400
ppm/K, and ±600 ppm/K
- Operating temperature range of -55 °C to +155 °C
The Perspective:
Vishay's new high-reliability CRCW....-EL thick film
power resistor provides designers with an extremely low resistance down to
10 mΩ, tight tolerances of ±1 % and ±5 %, and low TCR down
to ±100 ppm/K for current- sensing applications. The device is
offered in three case sizes: the 0603 (0.1 W), 0805 (0.125 W), and 1206
(0.25 W).
Availability:
Samples and production quantities of the new thick
film power resistor are available now, with lead times of six to eight
weeks for larger orders.
