Mouser is now stocking the CoolZorb 400 Series Thermal and EMI absorbent
material from Laird Technologies. The CoolZorb 400 is a sponge-like material
applied to electronic components that is effective in both dissipating heat
and absorbing electromagnetic interference (EMI). The CoolZorb 400 is used
like traditional heat sink compounds and is applied between an IC and a heat
sink, while demonstrating significant advantages over traditional heat sink
compounds including improved heat transfer and EMI suppression.
The new material is designed for IC thermal management and EMI mitigation
for electronics equipment. Electromagnetic interference is a significant
problem with modern high-speed electronics equipment. EMI can interfere with
the proper operation of many electronic systems by inducing unwanted
electric currents into wiring and PC board traces, as well as causing
self-heating in magnetically conductive metals. Another problem with
high-speed electronics is the heat generated by ICs running at high clock
speeds. All high speed ICs must dissipate heat or equipment may malfunction
or even become permanently destroyed.
The Laird CoolZorb 400 series is a hybrid EMI absorbent and thermal
management material that is used like traditional heat absorbent compounds.
The CoolZorb is composed of a silicone gel binder that gives the material a
tackiness typical of standard thermal gap filler materials. The CoolZorb's
material demonstrates thermal conductivity rated at 2.0W/mK, and EMI
suppression starting at the microwave frequency range with high EMI
suppression at and above 5GHz.
CoolZorb suppressors are ideal for compact electronic devices such as
medical equipment, Wi-Fi and other RF modules, power supplies, and low power
consumer electronics, says the company.
