Battery Chargers IC - (47 companies)
Battery charger ICs are integrated circuits (IC) that are used to charge batteries. Search by Specification | Learn more about about Battery Chargers IC

Crystals - (278 companies)
Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted.

PIN Diodes - (40 companies)
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Oscillators - (439 companies)
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs. Search by Specification | Learn more about about Oscillators

Charge Pumps - (18 companies)
Charge pumps are circuits that generate higher voltages from low voltage inputs by using capacitors as storage elements. They are used in notebook computers and mobile phones. Learn more about about Charge Pumps
