Ceramic Resonators - Ideal low cost Microcontroller Clock Oscillator

Ceramic Resonators with integrated capacitors are ideal accurate low cost oscillators for Microcontrollers in frequency from 1.79 to 50MHz. We offer not only industry standard frequencies, but specifically designed useful frequencies for MCU without floating point programming. Baud rate frequencies offer popular RS232 serial port communication, such as 9600 bps, without the requirement of an UART port. Bit rate frequencies are hexadecimal value timings great for precise I/O port pulse periods outputs or inputs.

ZTS Ceramic Resonator® 3 leads through hole and ZTSC surface mount, integrated with 30pF load capacitors are great oscillators for MCU, such as 8051/48/31, PIC16/17, 68HC05/08/11, Z8, SMC62, COP8, MSM64/65, H8, ...etc.
These ceramic resonators have fast start up rise time typically at 50µsec. Frequency accuracy is ± 0.005 fosc, (±0.5% frequency tolerance). Operating temperature range is from -20C to +80C. Volume price of popular frequency such as ZTS 4.00MHz is below 20¢ each. Average production lead time is 2 to 4 weeks.

Ceramic resonators are well suited for low power battery applications on Vcc as low as 1.8 Volt to and minimal current to below 1 mWatt power. Advantages of ceramic resonators compare with quartz crystals are ¼ in cost, ease of PCB auto insertion, reflow soldering & washable, excellent temperature range, and small physically size similar to ceramic capacitors.

Integrity Technology Corporation also produces industry standard ZTA Ceramic Resonators® and ZTB Ceramic Resonators® without capacitor for frequency from 400KHz to 50MHz. Please factory for ZTS through hole in bulk and ZTSC and ZTBF Surface Mounted in Tape and Reel options.
