Sound pressure level: 85DB 10cm The input voltage: 30vp-p max Operating Temperature: -20~70 Clear sound Ultra-thin and lightweight Low power consumption for voltage type
BC557 Transistor can be used as Amplifier BC557 Transistor can be used as a switch Responsive to current Output impedance is less Life span is good Noise operation is less Circuit design is simple Uses less power supply Quick action at the circuit
Low density: lightweight, low inertia. Uniformity of parts. Capability to absorb shock and vibration as a result of elastic compliance. Ability to operate with minimum or no lubrication, due to inherent lubricity. The relatively low coefficient of friction. Corrosion-resistance; elimination of plating, or protective coatings. The quietness of operation. Tolerances are often less critical than for metal gears, due in…
