What are the key features of ERJ-6DQF1R0V?
- 1.0 Ω ±1% current sense resistor with AEC-Q200 automotive qualification for reliable operation to +155°C
- 0805 SMD package rated at 0.25 W enables compact high-current sensing in automotive battery and motor control circuits
- ±100 ppm/°C temperature coefficient ensures stable resistance and accurate current measurement across the full automotive temperature range
- Thick film construction provides consistent resistive element performance under mechanical stress and thermal cycling in harsh automotive environments
What is ERJ-6DQF1R0V used for?
The ERJ-6DQF1R0V is used as a precision current sense shunt in automotive battery management systems, EV motor drive controllers, and DC-DC converter current feedback loops where accurate, low-resistance current measurement is essential for safe operation. Its AEC-Q200 qualification and -55°C to +155°C temperature range make it reliable in under-hood automotive environments and in industrial motor control boards subject to wide thermal cycling. The 0805 footprint and 1% tolerance also make it suitable for consumer electronics power management circuits requiring cost-effective current sensing.

Frequently Asked Questions
How does the 1.0 Ω value of the ERJ-6DQF1R0V affect voltage drop and power dissipation in a current sensing application?
At a 0.5 A sense current, the 1.0 Ω ERJ-6DQF1R0V develops a 0.5 V sense voltage, which is easily measurable by most ADCs and op-amp sense amplifiers without amplification. Power dissipation at 0.5 A is 0.25 W, which equals the resistor's rated maximum, so designs sensing currents above 0.5 A should use a lower value current sense resistor or ensure adequate thermal derating to stay within the 0.25 W power rating.
Why is AEC-Q200 qualification important for using the ERJ-6DQF1R0V in automotive motor control designs?
AEC-Q200 qualification verifies that the ERJ-6DQF1R0V has passed the Automotive Electronics Council's stress test requirements for passive components, including thermal shock between -55°C and +155°C, humidity, vibration, and load life testing at elevated temperatures. This qualification provides confidence that the 1.0 Ω, 1% resistor will maintain its accuracy and reliability throughout the 10 to 15 year life of automotive motor control and battery management systems without drift beyond the ±100 ppm/°C temperature coefficient specification.
What measurement accuracy can a designer expect from the ERJ-6DQF1R0V across the automotive temperature range?
With a 1% initial tolerance and ±100 ppm/°C temperature coefficient, the ERJ-6DQF1R0V has a worst-case resistance deviation of ±1% at 25°C. Across a 130°C temperature range from -55°C to +125°C, the temperature coefficient adds ±1.3% additional drift, giving a total worst-case resistance error of approximately ±2.3%. For most automotive current sensing applications this accuracy is sufficient, but designers needing tighter current measurement accuracy should combine the resistor with a precision gain-trimmed current sense amplifier.
What is the rated power of the ERJ-6DQF1R0V and how should it be derated for reliable long-term use in industrial environments?
The ERJ-6DQF1R0V is rated at 0.25 W at 70°C ambient, with power derating required above 70°C. Per standard passive component derating practices, a 50% derating factor is recommended for high-reliability industrial or automotive applications, limiting continuous power dissipation to 0.125 W. This means the maximum continuous current in a 50%-derated application is approximately 0.35 A through the 1.0 Ω resistor, which should be verified against the actual circuit operating conditions.
