Frequently Asked Questions

What are the key electrical specifications of the RN73C2A1K13B thin-film resistor?

The RN73C2A1K13B is a 1.13 kOhm thin-film precision resistor with ±0.1% tolerance, ±10 ppm/°C temperature coefficient, and 0.1 W power rating in a compact 0805 SMT package, providing stable and accurate resistance for voltage dividers, analog signal conditioning, and precision measurement bridge circuits.

How does the ±10 ppm/°C temperature coefficient of RN73C2A1K13B improve circuit accuracy across temperature?

The RN73C2A1K13B's ±10 ppm/°C temperature coefficient limits resistance drift to only 0.001% per degree Celsius, keeping the 1.13 kOhm value highly stable across varying ambient temperatures. This ensures accurate gain-setting, voltage division, and Wheatstone bridge performance in precision instrumentation and medical devices operating across wide environmental temperature ranges.

In which precision analog designs does the RN73C2A1K13B outperform standard thick-film chip resistors?

The RN73C2A1K13B outperforms thick-film alternatives in ADC reference networks, op-amp feedback dividers, and Wheatstone bridge arms where better than ±0.1% initial accuracy and ±10 ppm/°C drift control are required. Its thin-film construction also delivers lower noise and better long-term stability than thick-film counterparts across the full -55°C to +155°C operating range.
