XL-IRM0038C-38A Infrared Receiver: SMD Integration & Signal Stability

📌 Product Overview

The XL-IRM0038C-38A is a miniaturized infrared receiver module designed for surface-mount technology (SMT) assembly. It integrates a high-sensitivity PIN photodiode and a low-power preamplifier IC into a compact, epoxy-molded package with dual shielding to minimize electromagnetic interference. 💡 With a carrier frequency of 37.9 kHz, this component is engineered to provide stable signal decoding in space-constrained designs like set-top boxes and air conditioners. The device supports a wide operating voltage range (2.5V to 5.5V) and features TTL/CMOS compatible output, making it a versatile choice for low-power remote control applications.

🎯 Typical Applications

This component is optimized for short-to-medium-range infrared data reception in consumer and industrial sectors. Common implementation scenarios include:

  • Consumer Appliances: Remote control interfaces for air conditioners, fans, heaters, and humidifiers.
  • Multimedia Systems: Signal reception for TVs, DVD players, set-top boxes, and vehicle-mounted entertainment units.
  • Industrial & Peripherals: Sensor inputs for industrial automation instruments, computer peripherals, and induction sanitaryware.
  • Automotive & Lighting: Integration into automotive electronics and lighting control systems requiring remote activation.

📊 Key Technical Specifications
