Frequently Asked Questions (FAQ)
What is the RER50F78R7RCSL resistor and what are its main specifications?
The RER50F78R7RCSL is a 78.7 Ohm ±1% 20W wirewound chassis mount resistor manufactured by Vishay Dale. It's part of the military-grade MIL-PRF-39009 RER50 series and features aluminum housing with flanged mounting. The resistor operates reliably across a wide temperature range from -55°C to 250°C, making it suitable for demanding industrial and military applications.
What makes this resistor suitable for military and aerospace applications?
This resistor meets MIL-PRF-39009 military specifications and offers ±1% tolerance with a low temperature coefficient of ±20ppm/°C, ensuring stable performance in extreme conditions. Its moisture-resistant construction, non-inductive design, and low failure rate (R 0.01%) make it ideal for military, aerospace, and defense electronics where reliability is critical.
What is the power rating and operating temperature range of the RER50F78R7RCSL?
This 20W wirewound resistor operates continuously from -55°C to +250°C, providing excellent thermal stability across extreme temperature variations. The high power rating and wide operating range make it suitable for high-performance military equipment, industrial control systems, and outdoor applications.
Is this resistor RoHS compliant and what is its moisture sensitivity level?
The RER50F78R7RCSL is RoHS non-compliant due to its military-grade specifications, but it features MSL Level 1 (Unlimited) moisture sensitivity, meaning it requires no special moisture protection during storage and handling. This makes it convenient for inventory management and field deployment.
What mounting options and physical dimensions does this chassis mount resistor offer?
The resistor features flanged solder lug mounting with dimensions of 1.062" L x 1.080" W (26.97mm x 27.43mm) and a maximum seated height of 0.561" (14.25mm). The aluminum housing and axial case design provide secure chassis mounting suitable for high-vibration and high-temperature environments.
