What is ERJT08J301V used for?
The ERJT08J301V 300Ω resistor is commonly used in current-limiting circuits for LEDs and opto-isolators, signal conditioning networks, and pull-up/pull-down configurations in digital logic and microcontroller systems. Its 0.33W power rating in the 1206 package supports moderate current handling suitable for RS-485 bus termination networks, UART interface bias, and sensor front-end circuits. The component is equally applicable in industrial control panels, consumer electronics, and test equipment where space and power balance are important design considerations.

Frequently Asked Questions
What resistance and power rating does the ERJT08J301V provide for LED current limiting?
The ERJT08J301V offers 300Ω resistance at ±5% tolerance with a 0.33W power rating. For a standard 5V supply driving a 20mA LED with a 2V forward voltage, this resistor limits current to approximately (5V - 2V) / 300Ω = 10mA, operating well within its power budget of 0.03W versus the 0.33W rated limit.
How does the ±200ppm/°C TCR of ERJT08J301V affect resistance stability over an industrial temperature range?
Over a typical industrial range of -40°C to +85°C, representing a 125°C span, the ±200ppm/°C TCR causes the resistance to drift by up to ±2.5% from its nominal 300Ω value. This results in a resistance window of approximately 292.5Ω to 307.5Ω, adequate for non-precision biasing, filtering, and current-limiting roles but insufficient for precision measurement applications.
Can the 1206 footprint of the ERJT08J301V be substituted with a smaller 0805 resistor of the same value?
A 300Ω 0805 resistor is physically interchangeable in terms of resistance value but is typically rated for 0.125W versus the ERJT08J301V 0.33W rating. If the application requires more than 0.125W power dissipation — for example in RS-485 termination with higher bus voltages — the larger 1206 package is necessary to avoid thermal overstress on the smaller component.
Is ERJT08J301V suitable for RS-485 bus termination and what configuration would be used?
For standard RS-485 bus termination, a 120Ω resistor is the recommended value across the differential pair. The ERJT08J301V at 300Ω is not a match for classic single-resistor termination, but two 300Ω units placed in parallel yield 150Ω, close to the characteristic impedance. Alternatively, it suits bias resistor networks where 300Ω pull-up and pull-down resistors set the bus idle state to a defined logic level.
