Technical specifications, handling precautions, and soldering guidelines for the Stanley 1111C Series Ultra Compact SMT LED.
Table of contents
Product Overview
The Stanley 1111C Series is an ultra-compact SMT LED designed for high-density applications. It meets industry standards for the 1608 (0603) footprint and provides a bright, wide, and uniform spatial distribution. These LEDs are ideal for mobile devices such as cellular telephones, PDAs, and pagers, as well as industrial and medical instrumentation.
Electro-Optical Characteristics
The series is available in various colors including Red, Orange, Yellow, Yellow Green, Green, and Pure Green. Key performance metrics such as luminous intensity, peak and dominant wavelengths, forward voltage, and viewing angles are provided for each specific model (BR1111C through BG1111C). All characteristics are measured at an ambient temperature of 25°C.
Absolute Maximum Ratings
To ensure reliability, users must adhere to the specified maximum ratings. The operating temperature range is -30°C to +85°C, with a storage temperature range of -40°C to +100°C. Power dissipation is limited to 57.5mW for the Red model and 70mW for all other colors. Forward current should not exceed 25mA under standard conditions.
Handling and Soldering
Proper handling is critical to prevent damage to the chip. Soldering conditions must be strictly controlled: when using a soldering iron, the tip temperature should not exceed 280°C for a maximum of 3 seconds. For dip soldering, preheating should be between 120°C and 150°C, with a bath temperature of 260°C for a maximum of 5 seconds. Reflow soldering profiles are also provided to ensure component integrity.
Cleaning
If cleaning is necessary, use ethyl or isopropyl alcohol for less than 1 minute at temperatures below 40°C. If ultrasonic cleaning is used, it must be performed at an appropriate output level after confirming that it does not damage the LED resin body or mounting.

Practical help
Common problems
LED damage during soldering
Ensure soldering iron tip temperature does not exceed 280°C and contact time is under 3 seconds.
Resin body damage during cleaning
Use only ethyl or isopropyl alcohol; limit cleaning time to under 1 minute and temperature below 40°C. Use ultrasonic cleaning with caution.
Before use
- Verify the specific model number (BR1111C to BG1111C) for correct wavelength and intensity requirements.
- Ensure the PCB design matches the 1608 (0603) footprint dimensions.
- Check that the ambient temperature is within the -30°C to +85°C operating range.
- Confirm the forward current (IF) does not exceed 25mA.
- Ensure the reverse voltage (VR) does not exceed 4V.
Specs in practice
- Forward Voltage (VF)
- The voltage drop across the LED when conducting current; typically 1.7V to 2.2V depending on the color.
- Luminous Intensity (IV)
- The brightness of the LED measured in millicandelas (mcd) at a forward current of 20mA.
- Viewing Angle
- The angle at which the luminous intensity is half of the peak value; 140° or 150° for this series.
Model compatibility
- Designed for 1608 (0603) standard footprints.
- Not suitable for environments exceeding 85°C operating temperature.
- Requires specific pulse width and duty cycle (≤1msec, ≤1/20) for peak forward current ratings.
