UNR521000L分立半导体产品的晶体管-双极（BJT）-单预偏置规格书PDF中文资料

UNR521000L属于分立半导体产品的晶体管-双极（BJT）-单预偏置。由松下电器制造生产的UNR521000L晶体管 - 双极（BJT）- 单，预偏置预偏置双极晶体管具有内部电阻器，设计用于在未施加输入信号的情况下将器件保持在偏置或工作点附近。晶体管偏置可使晶体管更有效地工作，并产生稳定、无失真的输出信号。预偏置晶体管减少了所需的外部电路元器件数量，从而可降低项目成本。

Feature

General

A few seconds after tuning on the unit,you can start recording to DVD-RAM,HDD.

You can switch the operation of this function (ON/OFF) on the menu screen. .

Quick start(REC) principle

In the power-off at Quick start, only power supplies for video IC,tuner and storage media are cut off.

When the REC button is pushed a few second after the power button is pushed, Audio and Video data are stored in

DDR SDRAM before a storage media(DVD-RAM or HDD) preparation.

*Preparation time → DVD-RAM: Fabout 8seconds

After a storage media(DVD-RAM or HDD) preparation,A udio and Video data are transfer from DDR SDRAM to the

storage media.
