Make A Wish for Electronic Component Market's 2011

This January, like last, as forecasters see that the economy grows at a rate that is neither too hot nor too cold. However, as for electronic components industry, analysts expect the sales seems quite optimistic,.

When looking back to 2010, what is your most benefits after a year's hard working in electronic market. whatever it was, it was now a page of history in our fighting experience.

In 2010, we see so many upgrading electronic devices like iphone and ipad became the doubtless leaders on market, which drove worldwide fans almost crazy in the past several months and give global electronic suppliers a good harvest year in 2010.

As for 2011, we should also bear a good wish in mind that the 2011 is another harvest year ahead.

Detailed informations of SD1209T3-A1

SD1209T3-A1 is a product of electromagnetic buzzers, which can be seen everywhere.

Below are 3 main features for such electronic components:

1. These high reliability electromagnetic buzzers are applicable to automobile equipment.

2. Compact, pin terminal type electromagnetic buzzer with 2048Hz output.

3. Pin type terminal construction enables direct mounting onto printed circuit boards.

SAFETY PRECAUTIONS FOR USING TDK Electromagnetic Buzzer——SD1209T3-A1

Please be sure to read the specifications of TDK Electromagnetic Buzzer before use.

1.       Please pay sufficient attentions to the warnings for safe. designing when using the buzzer. Incorrect usage may cause smoke or fire.

2.       Do not make sound on the buzzer when it is close to ears. Listening to the buzzer when it is close to ears, or continuant lis tening to it for an extended period, may result in hearing disor ders. Thoroughly warn consumers not to turn on the sound when the buzzer is close to ears.

3.       Do not exceed the rated operation voltage range when using the buzzer. If it is exceeded beyond the rated operation voltage, a built-in coil may generate heat, resulting in deterioration of the coil, which may cause a drop in sound pressure or a change in the terminal resistance value. If a rare short circuit occurs due to heat generated in the built-in coil, a large electrical current flows to the equipment used, possibly causing it to emit smoke or fire.

4.       The buzzer is a magnetic type sounder. Do not use it for any other purpose than a sound generation.

5.       Do not use the buzzer in other than atmospheric air.

6.       Do not use the buzzer in the following environments (excluding cases in which countermeasures are taken).

7.       After installing the buzzer when designing an apparatus, confirm that there are no abnormalities by performing a reliability evaluation test.

APPLICATIONS of SD1209T3-A1

SD1209T3-A1 can be seen in many electronic products such as: Clocks, travel watches, keyboards, toys, various alarms of automobile equipment.
