SCM2012FH-xxx_-I, “SCM2012FH” = P/N, “xxx” = Impedance, “_” = Tolerance, “-I” = Internal code.
Tolerance “_”: M: ± 20%
Small size & low profile
Maximum Temperature Rise: 15°C (when measured at 25°C ambient).
Impedance measured with HP4291B RF Impedance Analyzer
DCR measured using the 16502 milliohm meter.
Operating temperature: -40°C to +125ºC
Storage temperature: -40°C to +125ºC
Impedance and Current Range: From 67 Ohms (400 mA) to 120 Ohms (250 mA)
Unspecified values available on request.
MSL: Level 1.
E. Applications:
1.
2.
Common mode noise suppression of signal lines in high speed and high-density digital equipment, such as personal
computers and peripherals.
The cut-off frequency of HDMI for differential mode is 3.5 GHz and 6GHz respectively, so they don’t interfere
with higher-speed differential signals such as DVI, HDMI. The product is suited for use on the transmission side of
digital TVs, DVD recorders and liquid crystal projectors.
