The News:
Vishay Intertechnology's New 4-Terminal, 1 W Surface-Mount Power Metal Strip Resistor is Industry's First in 0612 Package Size With Resistance Range from 0.5 mW to 5 mW
Vishay Intertechnology, Inc. (NYSE: VSH) introduces a new surface-mount Power Metal Strip resistor that is the industry's first 4-terminal, 1 W current sensing resistor in the compact 0612 package size to offer a very low resistance range from 0.5 mW to 5 mW.
Ideal for a wide variety of current sensing, voltage division, and pulse applications
Manufactured using proprietary techniques that result in extremely low resistance values
Durable all-welded construction
The Key Specifications:
1 W power rating
0.5 mW to 5 mW resistance range
0612 package size
1.0 % tolerance
- 65 °C to + 170 °C operating temperature range
Thermal EMF of < 3 µV/°C
The Perspective:
Vishays new WSK0612 surface-mount Power Metal Strip resistor is the industry's first 4-terminal, 1 W current sensing resistor in the compact 0612 package size to offer a very low resistance range from 0.5 mW to 5 mW. The small size of the device allows it to replace larger current sensing resistors, saving space on the circuit board that in turn will create smaller and lighter products for the consumer.
Availability: Samples and production quantities of the new resistor are available now, with a lead time of four to six weeks for larger orders.
