The thermal resistance (Rth) of the RN55D1101FB14 is 250°C/W, which is not explicitly stated in the datasheet. This value can be obtained from Vishay's application notes or by contacting their technical support.
While the RN55D1101FB14 is a general-purpose resistor, it's not optimized for high-frequency applications. Vishay recommends using their high-frequency resistor series, such as the HF series, for frequencies above 100 MHz.
The RN55D1101FB14 has a maximum operating temperature of 155°C, which is relatively high. However, for applications exceeding 155°C, Vishay offers high-temperature resistor series, such as the HT series, which can operate up to 250°C.
Vishay recommends a soldering temperature of 260°C (±5°C) and a soldering time of 3-5 seconds (±1 second) for the RN55D1101FB14. This information can be found in Vishay's soldering guidelines document.
The RN55D1101FB14 has a moisture sensitivity level (MSL) of 2, which means it can withstand normal humidity levels. However, for applications in extremely humid environments, Vishay recommends using their resistors with a higher MSL rating or applying conformal coating.
