What are the key features of ERJT14J112U?
- 1.1 kΩ resistance for LED driving, biasing, and current-limiting at standard logic voltages
- 0.5 W power rating in a 1210 package enabling higher continuous current dissipation
- ±5% tolerance for general-purpose analog and digital circuit applications
- ±200 ppm/°C temperature coefficient maintaining stable resistance across operating temperatures
- 3.2 mm × 2.6 mm 1210 footprint compatible with automated pick-and-place manufacturing
- Pb-free and REACH compliant construction with JESD-609 e3 code for regulatory compliance
What is ERJT14J112U used for?
The ERJT14J112U is used in LED current-limiting circuits where a 1.1 kΩ resistor sets the forward current at 3.3 V or 5 V rails in indicator and display designs. Its 0.5 W power rating supports bias and feedback resistor roles in power management ICs and DC-DC converter circuits. The robust 1210 package also makes it a preferred choice for industrial and automotive boards requiring reliable SMD resistors with higher power handling than standard 0805 components.

Frequently Asked Questions
What forward current does the ERJT14J112U set for an LED on a 5 V rail with 2 V LED drop?
With 5 V supply and a 2 V LED forward voltage, the ERJT14J112U at 1.1 kΩ limits LED current to approximately 2.7 mA. This is suitable for low-brightness indicator LEDs, keeping power dissipation at around 7 mW, well within the 0.5 W rated limit.
When is the 1210 package of the ERJT14J112U preferred over an 0805 resistor of the same resistance?
The 1210 package of the ERJT14J112U offers a 0.5 W power rating versus the 0.25 W typical for 0805 resistors. Designers choose the 1210 when higher sustained current flows through the resistor, such as in power supply feedback networks or when operating in elevated ambient temperatures above 70 °C.
How does the ±200 ppm/°C temperature coefficient of the ERJT14J112U affect bias resistor accuracy?
At ±200 ppm/°C, the 1.1 kΩ resistance of the ERJT14J112U shifts by approximately 22 Ω over a 100 °C temperature span. For most bias and pull-up applications this 2% drift is acceptable, though precision feedback or gain-setting networks may require a ±100 ppm/°C or ±50 ppm/°C resistor.
