Hertz (Hz)
The basic unit of measurement of frequency. It is a measurement used to denote one complete occurrence of an event in one second.
The frequency of a crystal is measured in megahertz (MHz) or kilohertz (kHz). In Kingtronics we usually usd KHz.

Frequency 
Measured in Hertz (Hz), it is a periodic repetition of an event within a unit of time. 
In an electrical circuit, it is the number of times a resonator plate oscillates or vibrates in one second. The most common herts for Kingtroncis QKT is 32.768KHz

Frequency Tolerance
Often called Calibration Accuracy, it is the amount of frequency deviation from the specified nominal frequency at room temperature (25°C). 

This term is expressed as a minimum and maximum percent (%) or parts per million (ppm). Kingtronics can provide -20~+70, -40~+85, -10~+60

Load Capacitance
A capacitance, specified in picofarads (pF), presented to the crystal. 

The parallel load resonant frequency (FL) is a function of the load capacitance.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
