What are the key features of ERJP14F1200U?
- 120Ω at ±1% tolerance for precision termination and current-sensing applications
- Low TCR of ±100ppm/°C ensures stable 120Ω value across -55°C to +155°C temperature range
- 0.5W power rating in 1210 case supports designs requiring higher dissipation than 0805 resistors
- Pb-free and RoHS-compliant with JESD-609 e3 coding for global regulatory acceptance
What is ERJP14F1200U used for?
The ERJP14F1200U is commonly used as a CAN bus or RS-485 line termination resistor at 120Ω, providing matched impedance to reduce reflections in industrial field-bus networks. Its 0.5W 1210 package also suits current-sensing shunt circuits in motor control and battery management systems where stable resistance is critical. The ±100ppm/°C TCR maintains impedance accuracy in automotive and outdoor equipment across a wide temperature range.

Frequently Asked Questions
Why is 120Ω the standard termination value for CAN bus, and how does ERJP14F1200U meet that requirement?
CAN bus uses 120Ω termination at each cable end to match the differential characteristic impedance of twisted-pair wiring and suppress reflections at data rates up to 1 Mbit/s. The ERJP14F1200U provides 120Ω at ±1% tolerance, ensuring each node stays within the ISO 11898 allowed 108Ω to 132Ω termination window even after aging and temperature drift.
How much power does ERJP14F1200U dissipate in a 24V CAN termination circuit?
A single 120Ω terminator across a 24V common-mode bus sees at most the differential voltage, typically 1V to 3V. At 3V differential, dissipation is 3²/120 = 75mW — well below the 0.5W rating. Even in fault conditions where the bus reaches 7V, dissipation is 0.41W, still within the rated limit with a proper pad thermal design.
Can the tight TCR of ERJP14F1200U benefit an RS-485 termination used in outdoor industrial enclosures at -40°C to +85°C?
Yes, the ERJP14F1200U's ±100ppm/°C TCR limits the 120Ω value shift to ±1.25% over a 125°C span from -40°C to +85°C. This keeps termination impedance between 118.5Ω and 121.5Ω, satisfying TIA-485-A recommended termination tolerance and maintaining reliable data transmission at 10 Mbit/s even in outdoor industrial environments.
How does ERJP14F1200U compare to ERJP08F1200V for board space and power handling?
The ERJP14F1200U in 1210 case measures 3.2 mm × 2.5 mm and is rated 0.5W, while the ERJP08F1200V in 1206 case measures 3.2 mm × 1.6 mm and is rated 0.66W. For termination applications under 0.5W, ERJP14F1200U fits comfortably; for tighter layouts needing more headroom above 0.5W, the ERJP08 1206 package provides 32% more dissipation in a narrower footprint.
