What are the key features of ERJP08F1803V?
- 180 kΩ resistance with ±1% tolerance and ±100 ppm/°C TCR for precision feedback dividers and high-impedance bias networks
- Enhanced 0.66 W power rating in 1206 (3216 metric) package, exceeding the standard 0.25 W limit of conventional 1206 resistors
- Pb-free RoHS-compliant thick film construction with e3 moisture sensitivity classification for automotive and industrial applications
What is ERJP08F1803V used for?
ERJP08F1803V is used in high-voltage feedback dividers for switch-mode power supply controllers, where 180 kΩ upper-leg resistors set output voltage reference levels in buck and flyback converter designs. Its ±1% tolerance and ±100 ppm/°C coefficient maintain accurate voltage regulation across the -55°C to +155°C industrial temperature range. The enhanced 0.66 W rating accommodates transient power pulses in feedback and snubber networks without requiring a larger 1210 package.

Frequently Asked Questions
How does ERJP08F1803V enable high-voltage feedback sensing in a 400 V SMPS design?
In a 400 V flyback converter, ERJP08F1803V with 180 kΩ resistance can be stacked in series with a lower-leg resistor to create a voltage divider that scales 400 V down to a 2.5 V reference level. At a 400 V input, current through the divider chain is approximately 2.2 µA, with the 180 kΩ resistor dissipating 180 kΩ × (2.2 µA)² ≈ 0.87 mW, far below its 0.66 W rated limit. The ±1% tolerance ensures that output voltage set-point accuracy stays within ±10 mV at the reference node.
Why choose ERJP08F1803V over a standard 1206 0.25 W resistor for high-frequency pulse applications?
ERJP08F1803V is rated at 0.66 W versus 0.25 W for a standard 1206 resistor, providing 2.6 times more instantaneous power handling capacity. In high-frequency switching circuits with repetitive pulse loads, peak power during transient events can briefly exceed the average dissipation by a factor of 3 to 5 times. The 0.66 W rating ensures that these peak pulses remain within safe operating limits without requiring a larger 1210 package that would demand pad layout changes.
How does the ±100 ppm/°C TCR of ERJP08F1803V affect voltage divider ratio stability in an automotive ECU?
Over the automotive temperature range of -40°C to +125°C, a 165°C swing with ±100 ppm/°C TCR produces a maximum resistance change of ±1.65% in each leg of the divider. If both legs use ERJP08F1803V or a matched series from the same ERJP08 family, the ratio error partially cancels, limiting divider output variation to well under ±0.5% across the full range. This satisfies most 12-bit ADC accuracy requirements in battery voltage monitoring and temperature sensing applications.
Can ERJP08F1803V replace a 180 kΩ 0402 or 0603 resistor in a redesign requiring higher power handling?
ERJP08F1803V occupies a 1206 footprint (3.2 mm × 1.6 mm) versus 1.0 mm × 0.5 mm for 0402 or 1.6 mm × 0.8 mm for 0603, so it is not a mechanical drop-in replacement. However, the 0.66 W rating versus 0.063 W for 0402 or 0.1 W for 0603 provides 7 to 10 times more power headroom. A layout revision to accept the 1206 footprint is straightforward and justified when redesigns increase power dissipation requirements or when AEC-Q200 automotive-grade sourcing is needed.
