THICK FILM
SMD
hVc Series
Precision High-Value High-voltage Wraparound Chip
• High value chip resistors in thick film technology
• Low temperature and voltage dependency (low TCR and VCR)
• High working voltage up to 3000V
• Suitable for high vacuum applications—no organics
• Contact areas: Nickel-barrier/matte tin
• Wraparound terminals
