SNAPHAT M4T28-BR12SH1 48 mAh Lithium Coin Cell Battery With Crystal – 5 PACK

SNAPHAT M4T28-BR12SH1 48 mAh Lithium Coin Cell Battery With Crystal - 5 PACK FREE SHIPPING The M4Txx-BR12SH SNAPHAT®top is a detachable lithium power source for ST’s serial real-time clock and non-volatile TIMEKEEPER®surface-mount SOIC package The SNAPHAT top contains both the battery and crystal and is designed to be “snapped on” after the SOIC is surface mounted on the PC board. Thus the two-piece solution prevents the battery and crystal from being exposed to the high temperatures of the surface-mount process. All features: Provides battery backup power for serial real-time clock, non-volatile TIMEKEEPER® and supervisor devices in the 28- or 44-pin SNAPHAT®SOIC packageRemovable battery avoids heat associated with surface-mount processSnaps directly onto surface-mounted SNAPHAT SOIC

5PCS STMicroelectronics L7812CV Voltage Regulator IC REG LINEAR 12V 1.5A TO220

Lot of 5. ParametersOperating Temp Min Celsius0.0Operating Temp Max Celsius125.0ECCN USEAR99ECCN EUNECPacking TypeTubeRoHs compliantEcopack2GradeIndustrialPackage NameTO-220DescriptionThe L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. Key featuresKey featuresOutput current up to 1.5 AOutput voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 VThermal overload protectionShort circuit protectionOutput transition SOA protection2 % output voltage tolerance (A version)Guaranteed in extended temperature range (A version)
