SMD film resistor has S level failure rate

The E/H series of MIL-PRF-55342-qualified high-reliability thin film surface-mount resistor chips offer an “S” level failure rate of 0.001% per 1,000 hours. They come in 12 case sizes and feature 25 ppm TCR and 0.1% tolerance.

The series handles 50 to 1,000 mw in case sizes from 0402 to 2512 with 10 ohm to 6.19 Mohm resistance. Their operating temperature range is – 55° to + 125°C, noise is less than – 25 dB, and voltage coefficient is
