What are the key features of ERJT14J47RU?
- 47Ω thick film resistor in 1210 SMT package with ±5% tolerance
- 0.5W power rating enabling higher current handling than smaller 0805 or 1206 packages
- ±200ppm/°C temperature coefficient for stable resistance across industrial temperature ranges
- 1210 rectangular SMT body (3.2mm x 2.5mm x 0.6mm) suitable for high-density automated assembly
- Broad application range from current-limiting to termination resistors in power circuits
What is ERJT14J47RU used for?
The ERJT14J47RU is suited for current-limiting, termination, and damping resistor applications in power supply circuits, motor control interfaces, and high-speed digital signal termination networks. Its 47Ω value is a standard impedance-matching resistor for RS-485 bus termination, CAN bus termination, and coaxial cable line-end termination in industrial communication systems. The 0.5W rating and 1210 package provide enhanced power headroom compared to smaller SMT sizes, making it reliable in applications with moderate heat dissipation requirements.

Frequently Asked Questions
Can the ERJT14J47RU terminate a 100 Mbps Ethernet or RS-485 bus at 47Ω?
The ERJT14J47RU can serve as a termination resistor for RS-485 and similar differential bus interfaces that specify termination values between 47Ω and 120Ω. For RS-485 at 100 kbps to 10 Mbps, a 47Ω termination absorbs signal reflections effectively, and the 0.5W power rating comfortably handles continuous bus loading at 5V across 47Ω, which dissipates approximately 531mW peak.
How does the 0.5W rating of ERJT14J47RU benefit designs compared to a 0.25W 0805-packaged 47Ω resistor?
The 0.5W power rating of the 1210-packaged ERJT14J47RU doubles the power handling capacity of a typical 0.25W 0805 resistor, allowing operation at up to 153mA continuous current through 47Ω before derating. This extra headroom is important in motor control snubber networks, power supply output damping, and bus termination circuits where transient currents can momentarily exceed the steady-state limit.
How does the ±200ppm/°C TCR of ERJT14J47RU affect bus termination accuracy over a wide industrial temperature range?
With a ±200ppm/°C TCR, the 47Ω resistance of the ERJT14J47RU shifts by up to 200 parts per million per degree Celsius. Over a temperature range from -40°C to 125°C (165°C span), total resistance drift can reach ±3.3%, so the effective termination impedance varies between 45.4Ω and 48.6Ω. For most RS-485 and CAN bus terminations this drift is well within acceptable tolerance limits.
