In some applications, uniform watt density is appropriate. In others, the heater may require multiple heat zones with variable power densities so that additional power is directed toward areas experiencing greater heat loss. hubs.li/Q04DkGnC0

To everyone who has worn the uniform of the U.S. Armed Forces, thank you for your service. We honor you today. #VeteransDay

If the materials within a flex or rigid-flex design expand at significantly different rates, stress begins to build at the interfaces between them. hubs.li/Q04DPkxv0

UN38.3 testing applies to all primary and secondary lithium batteries. hubs.li/Q04DkCk10

Learn how these elements work together to control battery operation and create a layered protection strategy within a custom battery management system. hubs.li/Q04DF4ns0

A flexible heater can be designed to generate relatively uniform heat across its active area, but that does not necessarily mean the complete system will reach a uniform temperature. hubs.li/Q04CPqL60

Higher-Tg FR-4 systems were developed to provide improved thermal performance and reliability under these conditions. hubs.li/Q04CPqlf0

Radiated emissions, radiated susceptibility, conducted emissions, conducted susceptibility, and ESD testing evaluate different ways electromagnetic interference can affect a system. hubs.li/Q04DkC6d0

Distinguish warm-up power from holding power. A heater sized to reach temperature quickly may require substantially less average power once the assembly reaches its setpoint. The control system must accommodate both conditions. hubs.li/Q04CPnrd0
