Recommended Land Pattern
For flow soldering, land width should be 0.7 to 0.8 times the resistor width (W). For reflow soldering, land width can be set to 1.0 to 1.3 times the resistor width.
Soldering Conditions
Temperature: 140°C to 180°C for 60-120 seconds
Soldering Peak Temperature: 245°C ± 5°C for 20-30 seconds
Safety Precautions
Adhere to rated power and temperature derating curves.
Evaluate resistor performance under transient loads before use.
Avoid using halogen-based flux to prevent performance impairment.
Minimize soldering time and temperature to prevent damage.
Handle with care to avoid mechanical damage or coating removal.
Prevent excessive bending of the PCB to avoid stress on the resistor.
Do not immerse in solvents for prolonged periods.
Note: Datasheet was not processed please search the internet for the part number ERA-3EEB2491V for more details.
I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
