New WSL0603...18 0.20-W Surface-Mount Power Metal Strip®Resistor

The Key Benefits:

• Double the power capacity of the standard WSL0603-type device
• Features specially selected and stabilized materials for a high power-to-package-size ratio while maintaining the superior electrical characteristics of the Power Metal Strip®construction
• Utilizes Vishay's proprietary processing technique for extremely low resistance range of 0.01 Ω to 0.1 Ω at standard tolerances of ±0.5 % and ±1.0 %
• Provides the same TCR (±75 ppm/°C) and thermal EMF (< 3 µV/°C) as the standard WSL0603 resistor, while offering an excellent frequency response to 50 MHz, and very low inductance ranging from 0.5 nH to 5 nH

The Key Applications:

• DC/DC converters, power/Li-Ion battery management systems, and VRMs in computer and telecommunications systems
• Electronic controls, including driver information electronics, engine, chassis, and climate controls in automotive systems

The News:

Vishay Releases Industry's First Surface-Mount Power Metal Strip^® Resistor to Offer High 0.20-W Power Rating in Compact 0603 Package Size For Double The Power Capacity of the Standard WSL0603-Type Resistor

Vishay Intertechnology, Inc. (NYSE: VSH) announces the industry's first Power Metal Strip^® resistor to feature a high 0.20-W power rating in the compact 0603 package size.

• With a high-temperature capacity to +170 °C, the new resistor provides resistance to extreme temperatures, as well as to thermal and mechanical shock, moisture, and vibration
• All-welded construction features solderable terminations and a resistive element of either solid metal nickel-chrome or a manganese-copper alloy
• Provided in 8 mm tape-and-reel form

Key Device Specifications:

• 0.20-W power rating
• 0603 package size
• Resistance range of 0.01 Ω to 0.1 Ω
• Standard tolerances of ±0.5 % and ±1.0 %
• TCR of ±75 ppm/°C
• Thermal EMF of < 3 μV/°C
• Frequency response to 50 MHz
• Inductance range from 0.5 nH to 5 nH
• Temperature capacity to +170 °C

The Perspective:

Vishay's new WSL0603...18 is the industry's first 0.20-W surface-mount Power Metal Strip^® resistor in the compact 0603 package size. By featuring the same high power ratings of larger devices, the WSL0603...18 enables OEMs to use smaller PCBs, which in turn increases manufacturing speed and reduces raw material costs, while meeting market demand for more compact, higher-performing end products.

Availability:

Samples and production quantities of the WSL0603...18 resistor are available now, with a lead time of four to six weeks for larger orders.
