Introduction Electric Specifications Table 1-3: Electrical Specifications Specification Description Supply Voltage 1.8V to 3.6V DC (Supports Lithium battery voltage range)a Typical Current Tx 16mA (Only on Tx/Rx) Typical Deep Sleep <8µA (Connected) Typical Hibernate <1.9µA (Not Connected) Typical Dormant <900nA Operating Temperature -40°C to 85°C Storage Temperature -40°C to 105°C a. For using SLEEP MODE (for low power consumption), the maximum voltage is 3.8V. Rev 1 Apr.
2: Power Measurements with Melody All measurements made with Melody Smart configured to: SLEEP=ON, TRSE=ON, TRSM=1, WAKE=OFF. Please refer to Melody Smart UART manual for more details. UART disconnected to remove leakage, RX pin pulled high via a 5k6 resistor (resistor leakage current included in current measurement values). For Send/Receive tests wired loopback used on UART interface connecting TX to RX pins on device measured.

5: Solder Reflow Profile The solder profile is described below. Figure 5-1: Solder Profile Zone A: Preheat: This raises the temperature at a controlled rate, typically 0.5 - 2C/s. This will preheat the component to 120°C to 150°C to distribute the heat uniformly to the PCB. Zone B: Equilibrium1: In this zone, the flux becomes soft and uniformly spreads solder particles over the PCB board, preventing re-oxidisation. The recommended temperature for this zone is 150°C to 200°C for 60s to 120s.
A: Regulatory Certifications Caution: Unauthorized modifications or changes not expressly approved by Sierra Wireless could void compliance with regulatory rules, and thereby your authority to use this equipment.
Product Technical Specification Canada IC The BC118 module, upon commercial release, will have been granted modular approval by IC. Integrators may use the BC118 module in their end products without additional IC certification if the following conditions are met. • At least 20 cm separation distance between the antenna and the user’s body must be maintained at all times. • The BC118 module must not be collocated with any other transmitter within a host device.
