Precision chip resistors are sulfur & moisture resistant
Resistant to the effects of both sulfur and moisture, a series of thin film precision chip resistors have been unveiled by Stackpole Electronics. While thin film nichrome resistors typically have difficulty withstanding high humidity environments under low power, Stackpole's proprietary materials and processing protects the nichrome element and performs as well under high humidity testing as much more expensive technologies such as tantalum nitride film chips.
In addition, resistors that have printed palladium silver inner terminations are susceptible to contamination by sulfur causing resistors to open. Stackpole's unique termination material and design minimise the effects of sulfur yielding a part that is ultimately extremely robust and reliable under a wide variety of environmental conditions.
The RNCS-AS series is AEC-Q200 qualified and is a good choice for applications requiring precision and accuracy under unknown or unpredictable operating conditions such as outdoor controls, security and surveillance, instrumentation and test equipment.
Pricing for the RNCS-AS series varies with size, resistance value, tolerance and TCR.
