Resettable fuses - PolySwitch devices. A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits.
This is an accepted version of this page This is the latest accepted revision, reviewed on 2 December 2024. Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
Low-dropout (LDO) regulators operate similarly to all linear voltage regulators.The main difference between LDO and non-LDO regulators is their schematic topology.Instead of an emitter follower topology, low-dropout regulators consist of an open collector or open drain topology, where the transistor may be easily driven into saturation with the voltages available to the regulator.
To obtain better performance and lower costs, semiconductor manufacturers reduce the device geometries of integrated circuits. With each reduction the associated operating voltage must also be reduced in order to maintain the same basic operational characteristics of the transistors.
North-American built automobiles up to at least 1981 had electrical systems protected by cylindrical glass cartridge fuses rated 32 volts DC and current ratings from 4 amperes to 30 amperes. These are known as "SFE" fuses, as they were designed by the Society of Fuse Engineers to prevent the insertion of a grossly inadequate or unsafe fuse into ...
The first step (called SC-1, where SC stands for Standard Clean) is performed with a solution of (ratios may vary) [2] 5 parts of deionized water; 1 part of ammonia water, (29% by weight of NH 3) 1 part of aqueous H 2 O 2 (hydrogen peroxide, 30%) at 75 or 80 °C [1] typically for 10 minutes. This base-peroxide mixture removes organic residues.
3490E data cartridges are the same dimensions as 3480 cartridges and the tape media is the same, only longer. 3490E tape is optimized for 36-track recording heads, instead of 18-track recording heads. Nevertheless, some 3480 tape drives can record on 3490E media. Some 3490E tape drives are able to read tapes recorded by 3480 tape drives.
