What are the key features of ERJB1BFR47U?
- Three independent 1-watt elements for flexible load distribution and parallel redundancy
- ±1% tolerance with ±100 ppm/°C stability across -55°C to +155°C temperature range
- Low 0.47 ohm resistance minimizes power loss in high-current switching and converter circuits
What is ERJB1BFR47U used for?
The ERJB1BFR47U excels in power supply circuits requiring multi-channel current sharing, such as parallel diode or transistor base networks where three identical 1 watt resistors prevent thermal runaway. Its isolated element design enables independent use or parallel connection to achieve higher power ratings up to 3 watts total dissipation. Ideal for motor drive circuits, LED drivers, and battery charging systems where balanced current distribution is critical.

Frequently Asked Questions
What is the maximum continuous power dissipation for each individual element in the ERJB1BFR47U at 85°C ambient temperature?
Each of the three isolated elements in the ERJB1BFR47U is rated for 1 watt continuous power dissipation at 70°C ambient. At 85°C ambient, deration applies reducing the rating to approximately 0.85-0.9 watts per element. The three-element configuration allows up to 3 watts total dissipation when operating in parallel, making this network suitable for high-current applications requiring robust current limiting across multiple signal paths.
How does the ERJB1BFR47U 2010 package compare to discrete 0603 or 1206 resistor arrays for space-constrained PCB design?
The ERJB1BFR47U 2010 package measures 5.0 x 2.5 x 0.75 mm and contains three 1-watt elements in a single integrated unit. Compared to using three individual 0603 resistors (1.6 x 0.8 mm each) rated at 100 mW, the network saves approximately 35-40% board footprint while handling 10x the power per element. Three 1206 resistors would exceed the 2010 footprint, confirming the ERJB1BFR47U as the superior integration choice for dense power circuits.
What applications benefit most from the three isolated 0.47 ohm elements of the ERJB1BFR47U?
The three isolated 0.47 ohm, 1-watt elements excel in balanced-load applications such as: parallel MOSFET gate resistor networks (three gate resistors for three power switches), LED current-balancing circuits across multiple strings, and three-phase rectifier diode cathode resistors. The ±100 ppm/°C temperature coefficient ensures predictable behavior from -55°C to +155°C in automotive and industrial environments where thermal drift compensation is essential.
