The recommended land pattern for WSL25121L000FTA18 can be found in the Vishay Intertechnologies' application note AN42171, which provides guidelines for surface-mount resistors.
Yes, WSL25121L000FTA18 is compatible with lead-free soldering. Vishay Intertechnologies ensures that their resistors meet the requirements for lead-free soldering as per the RoHS directive.
The moisture sensitivity level (MSL) of WSL25121L000FTA18 is MSL 1, which means it can withstand a maximum of 30°C/60% RH for 168 hours.
While WSL25121L000FTA18 is a general-purpose resistor, it may not be the best choice for high-frequency applications due to its construction and materials. For high-frequency applications, consider using specialized resistors designed for high-frequency use, such as those from Vishay's HF series.
The thermal resistance of WSL25121L000FTA18 is not explicitly stated in the datasheet. However, it can be estimated based on the package size and material. A typical thermal resistance for a 2512 package is around 200-250°C/W.
