LOW CUT CORE (High μ type) TRMH

Non-split type


Since the core also provides high impedance at frequencies 1 MHz or less, it is useful to suppress conducted noise at around 150kHz.
As the number of cable turns increases, the impedance improves, and higher noise suppression can be obtained.
Resin coated core protects cables from damage caused by core edges. (Products whose Part No. has “E” as the last digit)
A wide variety of sizes are available. (Inner dia. 7.2–87.9mm)
