- 390 kΩ resistance in 1210 SMD package (3.2 mm × 2.5 mm × 0.6 mm)
- 0.5 W power rating for mid-power resistive applications
- ±5% tolerance suitable for general voltage-divider and biasing circuits
- ±200 ppm/°C temperature coefficient for stable operation across temperature ranges
- RoHS compliant (JESD-609 e3) and REACH compliant, lead-free
- Rectangular thick film construction for consistent performance and long-term reliability
What is ERJT14J394U used for?
The ERJT14J394U is used in voltage divider networks, feedback loops, and high-impedance biasing circuits in industrial sensors, measurement equipment, and consumer electronics where a stable 390 kΩ value at moderate power is required. Its 1210 footprint provides sufficient pad area for robust solder joints in demanding thermal cycling environments. The ±200 ppm/°C coefficient ensures resistance stability across commercial and industrial temperature ranges.

Frequently Asked Questions
What power can ERJT14J394U dissipate and how does this influence resistor selection for high-impedance circuits?
The ERJT14J394U is rated at 0.5 W continuous power dissipation. At 390 kΩ, the maximum RMS voltage across the resistor is approximately 442 V before reaching the 0.5 W limit, making it well-suited for high-voltage, low-current signal conditioning circuits.
How does the ±200 ppm/°C temperature coefficient of ERJT14J394U affect measurement accuracy over temperature?
With a ±200 ppm/°C coefficient, the resistance of ERJT14J394U can shift by up to 200 Ω per degree Celsius per 1 MΩ, or about 78 Ω per °C at 390 kΩ. This is acceptable for general-purpose designs but may require compensation in precision measurement applications.
Can the 1210 package of ERJT14J394U be substituted with a 0805 or 1206 package in an existing layout?
The 1210 package has a 3.2 mm × 2.5 mm footprint with 0.6 mm height, which is wider than a 1206 (3.2 mm × 1.6 mm) or 0805 (2 mm × 1.25 mm). Substituting requires PCB pad modification; however, the 1210 size supports the higher 0.5 W rating that smaller packages cannot achieve.
