Frequently Asked Questions (FAQ)
What is the RER75F3R74RC02 resistor and what are its main specifications?
The RER75F3R74RC02 is a 3.74 ohm wirewound chassis mount resistor manufactured by Vishay Dale, rated for 30W power dissipation with ±1% tolerance. It meets military standards (MIL-PRF-39009) and features a wide operating temperature range of -55°C to 250°C, making it suitable for demanding industrial and military applications.
What are the key features and benefits of this military-grade resistor?
This resistor offers excellent stability with a low temperature coefficient of ±50ppm/°C and moisture-resistant coating for enhanced durability. Its aluminum housing and flanged chassis mount design provide secure installation, while the military-spec construction ensures reliable performance in harsh environments.
What is the operating temperature range for the RER75F3R74RC02?
The RER75F3R74RC02 operates reliably across a wide temperature range from -55°C to 250°C, making it ideal for aerospace, defense, and extreme-environment applications where standard resistors would fail.
What mounting options and physical dimensions does this resistor have?
This resistor features flanged chassis mount design with solder lug connections for secure installation. Its compact dimensions are 49.99mm length × 28.96mm width × 15.87mm height (seated), making it suitable for space-constrained military and industrial equipment.
Is the RER75F3R74RC02 RoHS compliant, and what is its moisture sensitivity level?
The RER75F3R74RC02 is RoHS non-compliant but offers excellent moisture protection with MSL rating of 1 (unlimited moisture sensitivity), meaning it can be stored without time restrictions and is resistant to moisture ingress in typical operating conditions.
Quality Assurance (QC)
DiGi ensures the quality and authenticity of every electronic component through professional inspections and batch sampling, guaranteeing reliable sourcing, stable performance, and compliance with technical specifications, helping customers reduce supply chain risks and confidently use components in production.
