Note
(1) Rated DC current based on the maximum temperature rise, not
to exceed 40 °C at + 85 °C ambient
FEATURES
• Molded construction provides superior strength
and moisture resistance
• Tape and reel packaging for automatic handling,
2000/reel, EIA-481
• Compatible with vapor phase and infrared reflow
soldering
• Shielded construction minimizes coupling to other
components
• Material categorization: For definitions of compliance
