What are the key features of ERJP14J7R5V?
- 7.5Ω ±5% low-resistance value in 1210 SMD package (3.2mm × 1.6mm) ideal for current sensing, inrush limiting, and power rail decoupling
- 0.5W continuous power rating with -100 to +600ppm/°C TCR suitable for cost-optimized general-purpose resistor networks
- Thick film rectangular construction in a 1210 surface mount footprint enabling efficient pick-and-place assembly in high-volume PCB production
What is ERJP14J7R5V used for?
The ERJP14J7R5V is well-suited for current sensing and inrush current limiting applications in power supply circuits and battery charger designs, where a low 7.5Ω resistance in a 0.5W package provides adequate voltage drop for feedback measurement. It also serves as a gate resistor or damping element in switching converter designs to reduce ringing and EMI on MOSFET drive signals. Industrial motor control, LED driver circuits, and consumer power adapters benefit from its robust 1210 footprint and general-purpose ±5% tolerance specification.

Frequently Asked Questions
What current can flow through ERJP14J7R5V at its rated 0.5W power dissipation limit?
At the 0.5W continuous power rating of the ERJP14J7R5V with 7.5Ω resistance, the maximum safe current is approximately 258mA, calculated as the square root of (0.5W / 7.5Ω). In practical designs with derating to 70% of rated power, the operating current should be limited to around 180mA to ensure long-term reliability and avoid thermal stress on the resistive element.
How does the -100 to +600ppm/°C temperature coefficient of ERJP14J7R5V affect precision in current sense applications?
The asymmetric -100 to +600ppm/°C temperature coefficient of the ERJP14J7R5V means resistance can increase by up to 600ppm per degree Celsius at elevated temperatures. Over a 100°C operating range, this results in up to 6% resistance shift, which is significant in precision current sensing. For applications requiring better than 1% accuracy over temperature, a thin film resistor with ±50ppm/°C or better TCR would be more appropriate than this general-purpose thick film device.
When is a 1210 package like ERJP14J7R5V preferable to a 0805 package for a 7.5Ω low-resistance circuit element?
The 1210 package of the ERJP14J7R5V, measuring 3.2mm × 1.6mm, is preferable to an 0805 package when power dissipation exceeds 0.25W. For a 7.5Ω resistor carrying 180mA, the power dissipated is approximately 0.243W, which approaches the 0.25W limit of an 0805 device. The 1210 package with 0.5W rating provides a comfortable 100% headroom at that current, improving thermal reliability and component longevity.
Can ERJP14J7R5V be used as a gate damping resistor in a 12V MOSFET switching circuit?
Yes, the ERJP14J7R5V with 7.5Ω resistance is a practical gate damping resistor for 12V MOSFET switching circuits. Gate resistors in the 4.7Ω to 22Ω range are commonly used to slow gate drive transitions, reducing dV/dt-induced EMI and ringing on the switching node. At typical gate charge currents under 1A peak and average power well below 0.5W, the ERJP14J7R5V's ratings are more than sufficient for this application in DC-DC converters and motor drivers.
