Kingtronics 5V-7.5V Combined Type Ultra Capacitor, also called Double Layer Capacitors – DKT-DY

Famous brand of switch like Digi-Key, Avnet, RS Components, Galco, Sager Electronics,Kingtronics, they are with nice rebound effect. Tact switches are designed with a small footprint suited for mounting onto the surface of printed circuit boards (PCB).

How does a tactile switch work? They are on/off electronic switches that are turn on only when a certain amount of pressure is applied. The circuit is broken when tactile switch button is released and the pressure has been taken off.

What are Small Signal Transistors? Small Signal Transistors are transistors that are mainly used to amplify low-level signals but also can be used in On/off switches for general use; Bias supply circuits; LED diode driver; Infrared diode amplifier; Relay driver; Timer circuits; Audio mute function; High voltage ‘A’ class preamplifier; Telecom wireline interface circuits; AM/FM amplifier and local oscillator of FM/VHF tuner.

Typical hFE values for small signal transistors range from 10 to 500, with maximum Ic ratings from about 80 to 600mA.Maximum operating frequencies range from about 1 to 300 MHz. They come in NPN and PNP forms and are being introduced in the small SMD plastic packages such as SOT-23.

Kingtronics small signal transistors are offered with the latest silicon planar technology that ensures high reliability and fast switching performance. We carry below small signal transistors, which meet that features.
