Latest thin-film precision chips are sulphur and moisture resistant

Stackpole has developed a series of thin-film precision chip resistors that are resistant to the effects of both sulphur and moisture. Typically thin-film nichrome resistors 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, says the company. In addition, resistors that have printed palladium silver inner terminations are susceptible to contamination by sulphur causing resistors to open. Stackpole's unique termination material and design minimize the effects of sulphur 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 seen as 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.
