Stackpole nichrome resistors replace nitride-based parts

Raleigh, N.C. – Stackpole Electronics Inc. is marketing its latest RNCS series of passivated nichrome thin-film precision chip resistors as a low-cost alternative to tantalum nitride-based devices.

With a 30% lower price tag than its tantalum nitride equivalent, the RNCS series resistors features intermediate silicon-based passivation that provides an impervious barrier to moisture, which eliminates the potential for corrosion that can cause standard nichrome elements to degrade and eventually open. The RNCS Series is aimed at metering and instrumentation, controls, and remote monitoring for industrial and commercial applications, energy monitoring and control, telecom infrastructure, non-established reliability aerospace, RF and IF attenuators, fuel cell systems and assemblies, and biomedical instrumentation and control.

Key highlights:

• Sizes: Range from 0402 to 2512
• Tolerances: Down to 0.1%
• TCR: 15 ppm
• Resistance values: Range from 10 ohms to 1Meg.

Pricing: Ranges from $16 per thousand to $230 per thousand in full reel quantities.

Availability: 265 part numbers are in stock at Digi-Key with additional stock available from Stackpole directly.
