👇 Assembly Guidance:
- Use the recommended Pb-Free reflow temperature profile to prevent thermal shock.
- Avoid mechanical stress on the LED during the heating process.
- Allow the PCB to cool to room temperature immediately post-soldering before subsequent handling.
📈 Sourcing & Supply Considerations
When integrating the XL-IRM0038C-38X into your supply chain, consider the following factors to ensure continuity and quality:
- Compliance: The product is REACH and ROHS certified, meeting standard environmental requirements for global markets.
- ** counterfeit Risk:** Source components through authorized XINGLIGHT distributors or verified channels to guarantee specification adherence.
- MSL Management: Adhere to Level 3 moisture sensitivity handling during storage to prevent popcorn cracking during reflow.
❓ FAQ
Q: What is the recommended carrier frequency for this infrared receiver?
A: The XL-IRM0038C-38X is optimized for a carrier frequency of 37.9 kHz. While it has a bandwidth (fBW) of approximately 6 kHz, deviation from the center frequency may reduce sensitivity and range.
Q: Can this receiver be used directly with a 3.3V microcontroller?
A: Yes. The device supports a wide operating voltage range of 2.7V to 5.5V. Its output matches TTL and CMOS logic levels, making it compatible with standard 3.3V or 5V logic without the need for level shifters.
Q: What are the cleaning and storage requirements prior to assembly?
A: This component has a Moisture Sensitivity Level (MSL) of 3. If the packaging is opened, components must be soldered within a specified timeframe (usually 168 hours) or baked according to IPC/JEDEC standards to remove absorbed moisture.
Q: How does the reception distance vary with angle?
A: The maximum reception distance is approximately 12 meters at 0 degrees (head-on). At an angle of ±75 degrees, the effective distance reduces to approximately 5 meters, though it remains functional for most remote control use cases.
Q: What is the output logic state when no signal is received?
A: The output form is Active Low. This means the output pin remains at a logic HIGH level when no infrared signal is detected and pulls to logic LOW when a valid signal is received.
