Precision-grade thin-film chip resistors "RNCF"
Precision-grade thin-film chip resistors
【Ultra-high precision ±0.01%・Ultra-low TCR ±2ppm/℃】Precision-grade thin-film chip resistors｜Dramatically improving the accuracy of precision measurement and power control.
The "RNCF series" is a precision thin-film chip resistor that achieves an astonishing ultra-high precision specification with a resistance value tolerance of ±0.01% and a maximum temperature coefficient of resistance (TCR) of ±2 ppm/°C. It suppresses resistance value changes due to temperature variations (thermal drift) and aging to the extreme, dramatically reducing measurement and control errors in circuits. 【Features of RNCF】 【Industry-leading ultra-high precision】 Supports a resistance value tolerance of ±0.01% (maximum), significantly enhancing the accuracy of precision voltage divider and gain setting circuits. 【Remarkable low temperature coefficient (low TCR)】 Accommodates a wide range of TCR from ±2 ppm/°C to ±50 ppm/°C, reducing circuit drift caused by thermal environmental fluctuations. 【Rich lineup of 8 shapes】 Complete range from ultra-small 0201 (0603 mm) to 2512 (6332 mm), achieving both high-density mounting on boards and power supply. 【Excellent long-term reliability and environmental resistance】 Boasts outstanding aging stability with a resistance change rate of ≤ ±0.5% in durability tests (1000 hours) and high-temperature high-humidity load tests. 【Environmental consideration and design support】 Complies with RoHS directives. Immediate access to datasheets, provision of evaluation samples, and consultation for custom precision are available. *Requests for catalogs and specifications can be accessed via the URL below.
