📦 Package, Dimensions & Assembly Notes
- Package Type: Epoxy resin, semi-circular spherical top view.
- Dimensions (LxWxH): 5.0mm × 4.2mm × 4.5mm.
- Moisture Sensitivity: MSL 3. Baking is required if the floor life (168 hours) is exceeded prior to reflow.
- Soldering Guidelines:
- Reflow Soldering: Recommended for mass production. Max 2 cycles. Do not apply mechanical stress to the component during heating.
- Hand Soldering: Use for repair only. Use an iron < 30W with tip temperature < 300°C for max 3 seconds per pin.
- ESD Protection: Standard anti-static precautions should be observed during handling.
📈 Sourcing & Supply Considerations
- Compliance: Certified RoHS and REACH compliant, suitable for environmentally sensitive supply chains.
- Packaging: Supplied in tape and reel format compatible with standard automated pick-and-place machinery.
- Qualification: Verify carrier tape dimensions (EIA-481 standard) prior to volume feeder setup to prevent machine jams.
- Authenticity: Source through authorized channels to ensure MSL handling protocols have been met, preventing "popcorning" during reflow.
❓ Frequently Asked Questions
Q: What is the recommended operating voltage range for the XL-IRM0038C-38X?
A: The recommended operating voltage range is 2.7V to 5.5V, providing flexibility for both 3.3V and 5V MCU designs.
Q: Can this IR receiver be used in an environment with direct sunlight?
A: While the device has specific immunity to environmental interference (200LUX specified), direct sunlight can saturate the PIN diode. It is recommended to place the receiver behind a dark IR-transmissive cover or shield it from ambient light sources.
Q: What is the Moisture Sensitivity Level (MSL) and why is it important?
A: The XL-IRM0038C-38X is classified as MSL 3. This means it can be exposed to the factory floor for up to 168 hours before it must be soldered to prevent moisture-induced damage during high-temperature reflow.
Q: What data formats does this receiver support?
A: The datasheet indicates optimized decoding for continuous codes and support for common protocols including NEC, Toshiba, and RC5/RC6 formats.
Q: What are the constraints for hand soldering this component?
A: Hand soldering should only be performed for repairs. Use a soldering iron with power under 30W and a tip temperature below 300°C. The duration must not exceed 3 seconds per pin, and stress on the leads should be minimized.
