What are the key features of ERJP14J1R8U?
- Ultra-low 1.8Ω resistance in a 1210 SMD package enables high-current shunt sensing and inrush limiting with minimal voltage drop
- 0.5W continuous power rating allows reliable use in current-sense networks carrying up to 500mA at 1.8Ω without thermal derating
- RoHS/Pb-free compliant thick-film construction with JESD-609 e3 coding supports automated lead-free solder assembly
What is ERJP14J1R8U used for?
The ERJP14J1R8U is ideal for inrush current limiting, low-side current sensing, and source degeneration resistors in motor drivers and power converters where a low-value 1.8Ω resistor at 0.5W is required. Its 1210 package handles the thermal demands of circuits carrying several hundred milliamps on 5V to 24V rails without a heatsink. Industrial equipment designers also use this part in overcurrent protection snubber networks and LED dimming circuits requiring precise low-resistance ballasting.

Frequently Asked Questions
How much current can the ERJP14J1R8U safely carry in a low-side current-sensing application?
With a 0.5W power rating and 1.8Ω resistance, the ERJP14J1R8U can continuously carry up to approximately 527mA (√(0.5W ÷ 1.8Ω) ≈ 527mA) before exceeding its rated power. For reliable current sensing in motor drive or power supply circuits, keeping the operating current below 500mA provides adequate thermal headroom within the 1210 SMD package.
What does the asymmetric -100 to +600ppm/°C TCR specification mean for resistance drift in a high-temperature industrial environment?
The asymmetric TCR of -100 to +600ppm/°C means the 1.8Ω resistance can increase by up to 600ppm per degree Celsius above ambient. Over a 100°C temperature rise, this translates to a worst-case drift of up to +1.08Ω, shifting the resistance to as high as 2.88Ω. Engineers should factor this drift into the sensing circuit gain to avoid measurement errors in high-temperature industrial environments.
When would a designer choose ERJP14J1R8U over an 0805-footprint low-ohm resistor for a motor-drive current-limit circuit?
A designer selects the ERJP14J1R8U's 1210 case (3.2 mm × 2.5 mm, 0.5W) over an 0805 equivalent (typically 0.125W max) when the motor-drive sense current exceeds approximately 263mA through 1.8Ω, since the 0805 would exceed its power limit at that point. The ERJP14J1R8U's larger footprint provides 4× greater power dissipation, preventing thermal runaway in sustained-load motor control stages.
