Ultra-low TC 2ppm/°C, tolerance 0.01%! Thin film resistor 'USF'

Precision with a practical TC of zero! A resistor with an alumina ceramic structure that minimizes power coefficient drift due to self-heating to the utmost limit.

"Ultra-precise and ultra-low TC resistors that push the limits of analog circuit accuracy" The 'Type USF' from Cadock, USA, is an ultra-precise film resistor boasting top-class absolute temperature coefficient (up to 2 ppm/°C) and tolerance (±0.01%). **Main Features** - Overwhelmingly low TC: In addition to the 300 series (5-10 ppm/°C), the lineup includes the 200 series (2 ppm/°C) with two elements coupled back-to-back. - Excellent thermal dissipation package: The structure sandwiched with alumina ceramic substrate enhances thermal conductivity and prevents self-heating (power coefficient) drift during operation. - Maximum 2,500V compatibility: Despite being a thin-film resistor, it supports a continuous operating voltage of up to 2,500V. - Applications: Gain setting for ultra-high precision amplifiers, precision bridge circuits, high-accuracy reference voltage dividers. **Main Specifications** - Rated voltage: 300V to 2,500VDC - Resistance value range: 50Ω to 25MΩ - Absolute tolerance: ±0.01% / ±0.1% - Absolute temperature coefficient: 2 ppm/°C (200 series) / 5・10 ppm/°C (300 series) - Operating temperature range: -40℃ to +85℃
