What are the key features of ERJP08F3901V?
- 3.9 kΩ precision thick film resistor with ±1% tolerance for accurate gain-setting and voltage-divider circuits in 1206 SMD footprint
- 0.66W continuous power rating—33% higher than standard 0.5W 1206 resistors—enabling use in higher-current signal paths without package upgrade
- Low ±100 ppm/°C TCR limits resistance drift to ±0.5% across a 0°C to 70°C operating range for stable analog circuit performance
What is ERJP08F3901V used for?
The ERJP08F3901V 3.9 kOhm resistor is used in current-limiting circuits for LED arrays, base resistors in bipolar transistor driver stages, and precision voltage divider networks in 5 V and 12 V power management systems. Its 0.66W power rating and ±1% tolerance make it suitable for feedback resistor networks in DC-DC converter controllers and bias resistors in operational amplifier circuits requiring low temperature drift. The 1206 SMD package supports automated high-volume SMT assembly in telecommunications equipment, industrial automation boards, and consumer electronics.

Frequently Asked Questions
What is the maximum current the ERJP08F3901V can handle continuously at 25°C ambient?
At 25°C the maximum current is I = sqrt(P/R) = sqrt(0.66 / 3900) ≈ 13 mA. The 0.66W rating must be derated above 70°C ambient; at 100°C ambient the allowable power drops proportionally per the Panasonic ERJP08 derating curve. For circuits where current exceeds 10 mA at elevated temperatures, verify the dissipation against the derated power limit before finalizing the design.
How does the 0.66W rating of ERJP08F3901V compare to standard 1206 resistors, and when does the extra headroom matter?
Standard 1206 resistors are typically rated at 0.25W to 0.5W, while the ERJP08F3901V delivers 0.66W—roughly 32% more than a 0.5W part in the same footprint. This headroom is valuable in LED driver circuits where transient surge currents can briefly exceed steady-state levels, and in motor driver bias networks where PWM switching adds RMS dissipation beyond DC calculations. The extra power margin also provides a safety buffer in designs where PCB thermal resistance is higher than expected.
For a 12 V to 5 V resistive voltage divider with low-current ADC input, how accurate is the output voltage using two ERJP08F3901V resistors?
A two-resistor divider using a 3.9 kOhm ERJP08F3901V pair (one top, one bottom, giving a ratio of 0.5) yields 6 V on a 12 V rail at DC. With ±1% tolerance on each resistor and ±100 ppm/°C TCR, the worst-case divider ratio error is approximately ±2% at 25°C and up to ±2.5% over a 0°C to 70°C range, corresponding to ±120 mV to ±150 mV error at the ADC input. For measurements requiring better than 1% accuracy, a matched resistor pair or a trimming scheme is recommended.
