CTune1 1200pF ceramic capacitor (can be 1206, 0805 or 0603 size)
RTune1 300 ohms SMT resistor (can be 1206, 0805 or 0603 size)
RTrim1 10kΩ SMT resistor (can be 1206, 0805 or 0603 size, recommended tolerance of 0.1%)
CTune2 1200pF ceramic capacitor (can be 1206, 0805 or 0603 size)
RTune2 300 ohms SMT resistor (can be 1206, 0805 or 0603 size)
RTrim2 10kΩ SMT resistor (can be 1206, 0805 or 0603 size, recommended tolerance of 0.1%)
Note: The DATA, CLK and SMBALRT pins do not have any pull-up resistors inside the module. Typically, the SMBus master
controller will have the pull-up resistors as well as provide the driving source for these signals.
