What are the key features of ERJT14J271U?
- 270 Ω resistance with ±5% tolerance for current-limiting and voltage divider circuit applications
- 0.5 W power rating in a 1210 SMD case (3.2 mm × 2.5 mm) for higher dissipation than 0805/1206 alternatives
- ±200 ppm/°C temperature coefficient ensuring resistance stability across wide operating temperature ranges
- RoHS compliant Pb-free construction with JESD-609 code e3 meeting REACH requirements
- 0.6 mm low-profile package height enabling dense, slim PCB assemblies
What is ERJT14J271U used for?
The ERJT14J271U is used in LED driver circuits on 5 V to 12 V supply rails where a 270 Ω series resistor provides controlled current, and in voltage divider networks feeding precision ADC inputs in industrial sensor conditioning boards. Its 0.5 W power rating in a 1210 package handles moderate heat dissipation without needing a larger component. It is also suitable for pull-up networks in open-drain communication buses on embedded control boards.

Frequently Asked Questions
How does the ERJT14J271U's 0.5 W rating benefit LED current-limiting circuits on 12 V rails?
At 270 Ω on a 12 V rail driving a 2 V LED, the ERJT14J271U carries approximately 37 mA and dissipates around 370 mW — within its 0.5 W limit. This makes it suitable for high-brightness LED indicator circuits where smaller 0805 or 1206 resistors rated at 0.25 W to 0.33 W would be pushed beyond their thermal limits.
When should a designer choose the 1210 ERJT14J271U over a smaller 0805 or 1206 resistor with the same 270 Ω value?
The 1210 package of the ERJT14J271U provides a 0.5 W power rating versus 0.25 W for 0805 and 0.33 W for 1206, making it the right choice when dissipation requirements exceed those limits. Its larger 3.2 mm × 2.5 mm pad area also improves solder joint reliability in automotive and industrial designs subject to thermal cycling.
What environmental certifications does the ERJT14J271U carry and how does it comply with global regulations?
The ERJT14J271U is fully RoHS compliant with a Pb-free code of Yes and JESD-609 code e3, and it meets REACH compliance requirements. These certifications make it suitable for consumer electronics, automotive, and industrial products destined for European, North American, and Asian markets with strict environmental regulations.
