What are the key features of ERJT14J1R6U?
- Anti-pulse thick-film construction providing enhanced durability against ESD and high-voltage pulse stress in the 1210 package
- Low 1.6Ω resistance with 0.5W power rating enabling currents up to approximately 559mA for current-sense and power-path applications
- 1210 SMD case (3.2mm × 1.6mm, 0.6mm height) offering larger pad area for improved thermal dissipation at 0.5W
- Wide TCR range (-100 to +600ppm/°C) with ±5% tolerance suitable for non-precision power resistor roles
- Long lifecycle (YTEOL: 12) with RoHS and REACH compliance for industrial and automotive design longevity
What is ERJT14J1R6U used for?
The ERJT14J1R6U is used in current-sensing and current-limiting circuits for motor drive boards, power supply feedback networks, and LED driver output stages where a low 1.6Ω series resistor with 0.5W dissipation capability is required. Its anti-pulse 1210 construction suits ESD-protection series resistors on power input lines and inrush-current-limiting networks in embedded power systems. The component is also applied in bias resistor networks for transistor and FET gate drive circuits operating at supply voltages up to 24V.

Frequently Asked Questions
What is the maximum continuous current ERJT14J1R6U can carry at its 1.6Ω resistance and 0.5W power rating?
At a 0.5W power rating and 1.6Ω resistance, the ERJT14J1R6U can handle a maximum continuous current of approximately 559mA (I = √(0.5/1.6) ≈ 0.559A). In a 5V circuit with this resistor in series, the voltage drop at 500mA would be 0.8V, dissipating 0.4W, which is within the 0.5W rating with some thermal margin.
How does the anti-pulse characteristic of ERJT14J1R6U help in power-path protection for embedded systems?
The ERJT14J1R6U uses Panasonic's anti-pulse construction that allows the 1.6Ω resistor to survive high-energy short-duration transients—such as those from capacitive inrush currents at power-on or ESD discharge events—without shifting resistance beyond ±5% tolerance. A standard 1210 thick-film resistor rated 0.5W at 1.6Ω would degrade or drift significantly after fewer than 10 such pulse events, while the anti-pulse variant maintains stable resistance for thousands of pulses.
In an LED driver circuit requiring a current-sense resistor, what voltage drop does ERJT14J1R6U produce at 300mA?
At 300mA through a 1.6Ω sense resistor, the ERJT14J1R6U produces a voltage drop of 0.48V (V = 1.6 × 0.3), which is readily measurable by a comparator or ADC input with a millivolt-resolution reference. Power dissipated at 300mA is 0.144W, well below the 0.5W rating, providing ample thermal margin for continuous LED driver operation at ambient temperatures up to 85°C.
What does the YTEOL of 12 mean for incorporating ERJT14J1R6U in a 10-year industrial product lifecycle?
A YTEOL of 12 years for ERJT14J1R6U indicates Panasonic expects the component to remain in production for at least 12 more years from now, comfortably covering a 10-year industrial product lifecycle without a component change. This is critical for IEC 61010-certified industrial equipment where approved component lists are fixed and substituting a resistor requires costly re-testing and recertification if a product hits end-of-life.
