Description:Display Modules - LED Character and Numeric Blue 7-Segment 1 Character Common Anode 3.6V 10mA 0.512" H x 0.378" W x 0.276" D (13.00mm x 9.60mm x 7.00mm) 10-DIP (0.300", 7.62mm)
ROHM recommends a 4-layer PCB with a solid ground plane and a separate power plane for the LA-401BD. The input and output pins should be placed on the top layer, and the power supply pins should be placed on the bottom layer. Additionally, a 10uF capacitor should be placed between the VCC and GND pins to reduce noise and ensure stable operation.
To ensure proper biasing, the LA-401BD requires a voltage supply of 5V ± 10% and a current supply of 10mA ± 10%. The input voltage should be within the recommended range of 0.5V to 4.5V, and the output voltage should be within the recommended range of 0.5V to 4.5V. Additionally, the input and output impedance should be matched to minimize signal reflections and ensure optimal performance.
The LA-401BD has an operating temperature range of -40°C to +85°C. However, the device's performance may degrade at temperatures above 70°C, and it's recommended to operate the device within the range of 0°C to 70°C for optimal performance and reliability.
The LA-401BD has built-in ESD protection, but it's still recommended to take precautions during handling and assembly. Use an anti-static wrist strap or mat, and avoid touching the device's pins or exposed metal surfaces. Additionally, ensure that the PCB is designed with ESD protection in mind, such as using ESD-protection diodes or resistors on the input and output lines.
The LA-401BD should be stored in a dry, cool place with a temperature range of 5°C to 30°C and a relative humidity of 60% or less. Avoid storing the device in direct sunlight, high temperatures, or high humidity environments, as this can affect its performance and reliability.
