The application determines the cost-efficiency. For Consumer Electronics (TVs, Air Conditioners), standard molded plastic packages are sufficient. However, for Outdoor Applications or Industrial Equipment, you must source receivers with high ambient light rejection and UV-stabilized epoxy resin to prevent degradation from sunlight. For Smart Home/IoT devices, look for ultra-low power consumption (standby current <0.5mA) to extend battery life, which is a key selling point for premium end-products.
