POWER New technology ups Li-ion capacity
For use in portable equipment of all kinds, Rutronik provides Panasonic's 3.6V lithium- ion batteries in accordance with the 18650 standard. Thanks to nickel oxide based new platform(NNP) technology, the NCR18650 and NCR18650A achieve capacities of 2.9 and 3.1Ah respectively. Heat resistant layer (HRL) technology also optimises safety.
The heart of the battery is a new nickel-
based positive electrode, which enables high capacities. Thematerial and process technology also prevent an alloy negative

voltage tracking for systems that need to sequencemultiple rails for proper power up and down and 250 to 780kHz fixed frequency PLL capability for noise-sensitive applications that require the switching frequency of the regulator to be a set value. For low voltage loads such as Vcore of FPGAs and processors, the LTM4618 includes safety features such as output overvoltage and short- circuit protection.

This means that as shortage issues increase and lead times are pushed further and further out, our market knowledge helps our customers breathe easy knowing that their dedicated account team will find the parts they need to get the job done!
If you’re having problems managing inventories, lead times or just staying on track give us a call: +44 (0) 1635 555 999
topology and its high switching frequency operation are said to deliver fast transient response to line and load changes without sacrificing stability. The device operates from4.5 to 26.5V input supplies and regulates an output voltage from0.8 to 5.0V. Pricing starts at $11.30 each for 1,000- piece quantities.
