Power metal strip resistor boasts high 3W rating

Vishay Intertechnology Inc. announced a new surface-mount Power Metal Strip resistor in a 2512 case size that combines a very high power capacity of 3W with extremely low resistance values down to 0.0005 Ω. 

The advanced construction of the WSLP2512 resistor incorporates a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 PPM/°C) and specially selected and stabilized material. This results in a high-power resistor with an operating temperature range of – 65 °C to + 170 °C while maintaining the superior electrical characteristics of the Power Metal Strip construction.  

The resistors are intended for all types of current sensing and pulse applications, including switching and linear power supplies, instruments, power amplifiers, and shunts in automotive electronic controls such as engine, anti-lock brake, and climate controls; industrial controls, including down-hole test/measurement equipment for oil/gas well drilling; and consumer product controls such as inverter controls for HVAC systems.

Key highlights:

• Very high power to foot print size ratio (3W in 2512 package)
• Proprietary processing technique produces extremely low resistance values (down to 0.0005 W)
• Solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 ppm/°C over temperature range of 20 °C to 60 °C)
• Measures 0.250 in. x 0.125 in. x 0.025 in.
• Very low inductance 0.5 nH to 5 nH
• Frequency response to 50 MHz
• Low thermal EMF (< 3 μV/°C)
• Compliant to RoHS Directive 2002/95/EC
• AEC-Q200 qualified available

Pricing: Varies by application, volume, and region.

Availability: Samples and production quantities of the new resistors are available now, with a lead time of six to eight weeks for larger orders.
