Frequently Asked Questions

What tolerance and temperature coefficient does the RN73C2A20K5B provide for precision reference circuit designs?

The RN73C2A20K5B offers ±0.1% resistance tolerance and a low temperature coefficient of ±10 ppm/°C on its 20.5 kΩ value, ensuring stable and accurate resistance across a wide operating temperature range in precision instrumentation, measurement bridges, and voltage reference circuits.

How does the RN73C2A20K5B thin film construction outperform standard thick film resistors in precision analog designs?

Unlike standard thick film resistors with TCR values of ±100 ppm/°C or higher and 1% tolerances, the RN73C2A20K5B achieves ±10 ppm/°C TCR and ±0.1% tolerance, making it far more suitable for precision bridge networks, differential amplifier feedback, and ADC reference dividers within its 0.1 W power rating.

What is the maximum safe operating voltage for the RN73C2A20K5B at its rated power dissipation?

At its 0.1 W power rating and 20.5 kΩ resistance, the maximum operating voltage across the RN73C2A20K5B is approximately 45.3 V (derived from V = √(P × R)), a limit that must be respected to prevent self-heating and resistance drift in precision analog circuit designs.
