Current
compensated EMI noise suppression chokes for data and signal
line filtering
Current compensated EMI noise suppression chokes are designed for interfacing
and virtual elimination of electromagnetic interference(EMI) in integrated
services digital network (ISDN) systems. These chokes provide both differential
and common noise attenuation while allowing the differential signal to pass
through virtually undistorted.
Features
 |
high
attenuation over a wide frequency range
|
|
frequency
range to 2OOkHz
|
|
compact
and miniature sizes for high density packaging
|
|
excellent
quality at extremely competitive price due to high volume
production
|
|
complies
with CCITT.I.430 and corresponding national standards
|
|
Manufactured
in ISO-9000 approved facility.

Electrical Specifications
- Ln: Inductance of each winding measured at 16 kHz/5OmV
Tolerance: ±20%.
- In: Current rating per winding at 6O°C ambient*
- Ls: Leakage inductance of an individual winding when
all other windings are short circuited(f=lOOkHz/5OmV)
- Rcu: Nominal DC resistance of a winding
- Up: Test Voltage of 1,000 Vrms at 5OHz for 2 seconds,
winding to winding
Nominal Current: per winding, 5OHz, 40°C Ambient
DC Resistance: per winding
Nominal Voltage: 80 V -/ 42 V
* It is allowable to use higher current at lower ambient
temperature or lower current at higher ambient temperature as long as the
surface temperature of the choke does not exceed 85°C.
