Piezoceramic filters. Reference data

Imported (non-CIS countries) piezoelectric ceramic filters are marked with three elements:

FIRST ELEMENT - letters defining the functional designation: CFW, SFE, E (three-pin) - band-pass filters, T (four-pin) - band-pass (pass) filters, L, T, W, S (three-pin) - notch filters, J, D ( two-output) - reference (discriminator) filters;

SECOND ELEMENT - numbers indicating the average carrier frequency.

THIRD ELEMENT - a letter that can mean design, bandwidth, operating conditions, etc.

In some cases, the functional notation for bandpass filters is omitted, indicating only the resonant frequency and bandwidth.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

MPLAB PM3 universal programmer 19.02.2004

MICROCHIP Corporation announced the creation of a universal programmer MPLAB PM3, which can serve all microcontrollers of the PIC series released by the corporation and digital signal processors of the dsPIC series.

The device can be connected to a personal computer via a serial or parallel interface and allows programming directly from a computer. For example, programming a PIC18F8720 microcontroller with 128KB flash memory takes 20 seconds.
