HIGH CURRENT CHOKES
TYPE 7200
10µH - 10mH 10% Tolerance
Recommended Mounting Pitch — 1.25″
NOTES:
1. INDUCTANCE measured on QuadTech/GenRad 1659 RLC Digibridge at
1.0 KHz.
2. THE CURRENT RATING (Rated IDC) is based on 0.5 watt power
dissipation (I
2
R) for an approximate 20°C temperature rise. Depending
on the application, these units may be operated at higher currents.
The core material for the 7200 series has been chosen for optimum
current handling capability. Because this material has a relatively low
volume resistivity, the core will appear as a shunt resistance on the order of
1 Kilohm, which may have to be taken into account when determining total
power dissipation; e.g., if the induced voltage across the coil is 10 volts,
there will be a V
2
/R loss on the order of 0.10 watt, in addition to the I
2
R
losses associated with the winding.

3. INCREMENTAL CURRENT (INCR I) is the approximate current at which the
inductance will be decreased by 5% from its initial (zero-DC) value because
of saturation. If the current is increased beyond INCR I, the inductance will
continue to decrease as shown by the saturation curve below.
4. DIELECTRIC WITHSTANDING VOLTAGE: 1000 VRMS.
5. OPERATING TEMPERATURE RANGE: -55° to +105°C.
