What are the key features of ERJT08J51RV?
- 51 Ω resistance at ±5% tolerance for termination, current limiting, and damping applications
- 0.33 W power dissipation in a standard 1206 SMD package for moderate-load circuits
- ±200 ppm/°C TCR provides stable resistance across wide industrial temperature ranges
- Thick-film rectangular construction with consistent lot-to-lot resistance uniformity
- Panasonic ERJT08 series reliability for long service life in demanding environments
What is ERJT08J51RV used for?
The ERJT08J51RV is commonly used as a series termination resistor on high-speed signal lines, a current-limiting resistor for LED indicators at 3.3 V or 5 V, and a damping resistor in RF and switching converter circuits. The 51 Ω value closely matches standard 50 Ω impedance environments, making it suitable for transmission-line termination in digital or RF signal paths. Its 0.33 W rating in the 1206 package supports operation at moderate current levels without heatsinking.

Frequently Asked Questions
What resistance value and power rating does the ERJT08J51RV provide?
The ERJT08J51RV offers 51 Ω resistance with ±5% tolerance and a 0.33 W continuous power rating in the 1206 SMD package. At its rated power, the resistor can handle up to approximately 130 mA, making it well suited for signal line termination and LED current limiting at standard logic voltages.
Why is the 51 Ω value of the ERJT08J51RV particularly useful in digital and RF circuit designs?
The 51 Ω value is very close to the standard 50 Ω characteristic impedance used in RF and high-speed digital transmission lines. Placing the ERJT08J51RV as a series or shunt terminator minimizes signal reflections on controlled-impedance traces, reducing ringing and EMI in circuits operating above 10 MHz.
How does the ERJT08J51RV's temperature coefficient affect its use in outdoor or industrial equipment?
With a ±200 ppm/°C temperature coefficient, the 51 Ω resistance value changes by at most 10.2 Ω across a 100°C span, staying well within the ±5% tolerance band. This stability makes the ERJT08J51RV reliable for termination resistors in industrial and outdoor electronics exposed to -40°C to +85°C environments.
Can the ERJT08J51RV serve as a current-sense element in a low-power LED driver?
Yes. At 51 Ω, a forward current of 20 mA through an LED drops 1.02 V across the resistor, providing a measurable voltage for current sensing or PWM control feedback. The 0.33 W rating handles 20 mA continuously with only about 0.02 W dissipation, leaving substantial thermal margin in a compact 1206 footprint.
