What are the key features of ERJP08J1R5V?
- 1.5Ω ±5% low-resistance value with 0.66W power rating in 1206 SMD package for current sensing, inrush limiting, and power rail damping applications
- -100 to +600ppm/°C temperature coefficient providing cost-effective general-purpose performance in non-precision switching and power management circuits
- RoHS Pb-free with JESD-609 e3 and REACH Compliant construction supporting halogen-free assembly lines for EU, Japanese, and North American market products
What is ERJP08J1R5V used for?
The ERJP08J1R5V is used in current sensing and inrush current limiting circuits within DC-DC converters, battery chargers, and motor control boards where a cost-effective 1.5Ω resistance and 0.66W power dissipation capability are required. Its low resistance value and 1206 footprint make it suitable for LED driver current setting resistors and power supply soft-start networks operating at moderate current levels. Industrial control systems and consumer power adapters also use this resistor for EMI damping, gate charge limiting in MOSFET drivers, and overcurrent protection sense paths.

Frequently Asked Questions
What maximum continuous current can ERJP08J1R5V safely carry at its 0.66W power rating?
At the 0.66W power rating with 1.5Ω resistance, the ERJP08J1R5V can safely carry approximately 663mA continuous current, derived from the square root of (0.66W / 1.5Ω). In thermally derated designs at 50% of rated power, the practical current limit is around 469mA. This makes the resistor suitable for low-side current sensing in battery chargers and motor controllers handling currents in the 200mA to 500mA range.
How much voltage drop does ERJP08J1R5V produce at 400mA, and is this acceptable for a current sense application?
At 400mA, the ERJP08J1R5V with 1.5Ω resistance produces a voltage drop of 0.6V (V = 400mA × 1.5Ω), dissipating 0.24W of power — well within the 0.66W rated limit. A 0.6V sense voltage is measurable by most analog front-end ICs and microcontroller ADCs without additional amplification, making this resistor practical for direct current sensing in applications where a sub-1Ω shunt would produce too small a signal to measure accurately.
How does the -100 to +600ppm/°C TCR of ERJP08J1R5V affect a current sense circuit over temperature?
The asymmetric -100 to +600ppm/°C temperature coefficient means the ERJP08J1R5V resistance can rise by up to 600ppm per degree Celsius at elevated temperatures. Over a 100°C operating range, this could cause the 1.5Ω resistance to increase by up to 6%, shifting the current sense voltage by up to 6% from the calibrated value. For precision current measurement requiring better than 1% accuracy over temperature, a metal film or wirewound resistor with ±50ppm/°C or better TCR should be substituted for this general-purpose thick film device.
When is ERJP08J1R5V preferred over a 0.5W rated 1206 resistor at 1.5Ω for a power converter design?
The ERJP08J1R5V with 0.66W rating is preferred over a standard 0.5W 1206 resistor when the circuit operates at power levels between 0.25W and 0.66W continuously. In a 5V converter with 400mA current, the 1.5Ω sense resistor dissipates approximately 0.24W, but transient spikes or startup surges may briefly push power above 0.5W. The 0.66W ERJP08J1R5V provides a 32% power headroom advantage over standard 0.5W counterparts, reducing the risk of thermal degradation and extending component service life in the same 1206 footprint.
