What are the key features of ERJP08F3003V?
- 300 kΩ ±1% precision high-resistance value for accurate high-impedance voltage sensing and feedback dividers
- 0.66 W power rating in 1206 (3.2 mm × 1.6 mm) SMD package, supporting up to 445 V continuous without exceeding power limits
- ±100 ppm/°C TCR for stable resistance over wide industrial temperature ranges from -55°C to +155°C
What is ERJP08F3003V used for?
The ERJP08F3003V high-resistance thick film resistor is ideal for high-voltage sensing dividers, isolation barrier bias networks, and op-amp input protection circuits where 300 kΩ limits input current without loading the signal source. Its 0.66 W power rating allows the resistor to withstand transient overvoltage events up to 445 V momentarily in protection circuit applications. The 1206 footprint is compatible with standard pick-and-place processes in power supply and energy management PCB designs.

Frequently Asked Questions
How does ERJP08F3003V perform in a high-voltage sensing divider on a 400 V DC bus?
In a resistor divider from a 400 V bus, placing ERJP08F3003V (300 kΩ) at the top of the divider limits power dissipation to P = V² / R = (400)² / 300,000 ≈ 0.53 W, just within the 0.66 W rating. The ±1% tolerance and ±100 ppm/°C TCR keep the divider ratio accurate to within ±1.1% over a 0°C to 70°C range, suitable for industrial power meter front ends.
For op-amp input protection on a precision 5 V ADC, why choose a 300 kΩ resistor like ERJP08F3003V over lower values?
A 300 kΩ series resistor at the ADC input limits fault current to a safe 17 µA when +5 V is applied to a grounded protection diode (5 V / 300,000 Ω ≈ 17 µA). Lower resistance values such as 10 kΩ would allow 500 µA through the protection diode, risking latch-up in CMOS inputs. The ±1% accuracy of ERJP08F3003V also ensures consistent bandwidth limiting without altering the input pole frequency by more than 2%.
What makes ERJP08F3003V suitable as an alternative to metal film 300 kΩ resistors in instrumentation amplifiers?
The ERJP08F3003V offers ±100 ppm/°C TCR and ±1% tolerance comparable to standard metal film resistors, while its 1206 SMD package enables automated assembly that through-hole metal film parts do not support. At 300 kΩ, noise contribution is approximately 70 nV/√Hz at 25°C (√(4kTR)), acceptable for audio and low-bandwidth instrumentation amplifiers operating at gains below 100 where the input-referred noise floor is set by the amplifier, not the feedback resistor.
