Anti-moisture Thru-hole Resistors

Anti-moisture thru-hole resistors represent an important segment of the resistor market. There are many designs that require resistors to perform in high humidity environments and engineers need the mechanical stability and thermal characteristics of a thru-hole connection. We will examine the most common products for these requirements and discuss the benefits of using each for a given application.

Stackpole Introduces the RTAN Series Precision Thin Film Tantalum Nitride Chip Resistors

Stackpole Electronics, Inc. announces the release of their new RTAN series chip resistors. The AEC qualified RTAN is a Tantalum Nitride precision thin film resistor that is impervious to moisture corrosion. This type of thin film technology passes biased humidity testing at 85°C, 85% relative humidity, and 10% rated power for more than 1000 hours with very little shift in resistance. In addition, the materials and design are such that the RTAN is resistant to sulfur contamination and will pass the industry standard sulfur test ASTM B809-65 with minimal resistance shift.
