TRF250-120-2 Frequently Asked Questions (FAQ)

  • The recommended PCB footprint for the TRF250-120-2 is a rectangular pad with dimensions of 0.25 inches (6.4 mm) x 0.15 inches (3.8 mm) with a 0.05 inches (1.3 mm) radius corner.

  • Yes, the TRF250-120-2 is rated for operation up to 150°C, making it suitable for high-temperature applications. However, the device's performance and reliability may degrade at extreme temperatures.

  • To ensure proper soldering, use a soldering iron with a temperature of 250°C to 270°C, and apply a small amount of solder paste to the PCB pads. Use a soldering technique that minimizes the risk of overheating the component.

  • The TRF250-120-2 has a maximum surge current rating of 200 A, which is the maximum current the device can withstand for a short duration (typically 10 ms) without damage.

  • Yes, multiple TRF250-120-2 devices can be connected in parallel to increase the current rating. However, it is essential to ensure that the devices are properly matched and that the PCB design takes into account the increased current capacity.
