Chip resistors operate up to 240°C

Chip resistors operate up to 240°C

The HTH series of ultra-high-precision Bulk Metal Z1-Foil hybrid surface-mount chip resistors connected using gold wire bonding targets high-temperature applications to 240°C. The series also offers improved heat dissipation, providing nearly a 100°C extension in operating temperature range over precision thin-film chip resistors.

The devices provide an order of magnitude reduction in bulk metal foil element’s sensitivity to external and internal temperature changes, while providing long-term stability in high-temperature environments. HTH devices offer TCR of ±1 ppm/°C from –55° to 125°C and ±2.5 ppm/°C from–-55° to 220°C, 25°C ref. The resistors feature exceptional load-life stability to ±0.05% at 220°C for 2,000 hours at working power, long-term stability to ±0.05% at 240°C for 2,000 hours (no power), and tight tolerances to ±0.02%.
