Low TCR Resistors Offer Tight Tolerances

Using precision metal film chip resistors in hard-to-find tight tolerances, these new resistors come in three popular chip sizes of 1206, 0805 and 0603. Resistance values are 10 ohms to 1 Megaohm with tolerance of ±0.05% for 1206 chips, 10 ohms to 511 kiloohms with tolerance of ±0.1% for 0805 chips, and 10 ohms to 332 kiloohms with tolerance of ±0.1% chips. Standard TCR is ±50 ppm/°C with some values available to ±15 ppm/°C. Terminations have a nickel diffusion barrier.
