The MCSO1EL is available supplied either on tape and reel or packaged within trays. T&R standard pack size is 250~1000pcs and standard tray size is 91pcs per tray. Partial quantities may be supplied on tape (no reel), partial trays, or in bulk.

Product Description

The 2.5V MCSO1ELW oscillator is available over low frequency range of 10.0~50.0kHz. Specially developed for extreme environments the MCSO1ELW has optional -55 to +200°C operating temperature range, ideal for applications such as down-hole, avionics and geothermal. This oscillator also features excellent shock and vibration resistance.

The MCSO1ELW produces CMOS output and has very low ageing under extreme conditions. It is also available with SAC (Sn/Ag/Cu) tinned pad terminations, ideal for material-sensitive applications and manufacturing processes.
