The components are laser trimmed to achieve the required resistance tolerance. Terminations The wrap-around terminations have an electroplated nickel barrier and matte tin finish, this ensures excellent ‘leach’ resistance properties and solderability. Chips can withstand immersion in solder at 250°C for 90 seconds and are suitable for reflow or wave soldering mounting applications. Marking The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits. Chips are packed and mounted with marking side up. The LRF3W Chips are mounted with the actual resistor element mounted face down on its termination pads. Packaging LRF3W Resistors are supplied taped and reeled as per IEC 286-3. The standard quantity per reel is 1800 parts. Notes: 1. Full AEC-Q200 qualification applies to ohmic values ≥R02.
