Product Overview
The RN73H series are high-reliability metal film flat chip resistors designed for demanding applications. They offer high precision with tight resistance tolerances and excellent temperature coefficient of resistance (TCR). These resistors feature low current noise, a wide operating temperature range, and improved moisture resistance due to a special protective coating. They are suitable for various industrial control circuits and are compatible with both flow and reflow soldering processes. The series meets EU-RoHS requirements and is AEC-Q200 qualified.

Precautions for Use
Handle with care to avoid electrostatic discharge, especially in dry conditions or after prolonged vibration during packaging. Ionic impurities from flux, sweat, or saliva can cause electrical corrosion; thorough cleaning is recommended, especially when using RMA solder/flux or lead-free solder. Avoid direct contact of tape adhesive with the product during mounting. High-pressure shower cleaning may cause electrode exfoliation; evaluate before use if unavoidable.
