MINIATURE HIGH CURRENT CHOKES
TYPE 7070
1.0 µH-100 mH. 10% Tolerance
Recommended Mounting Pitch—.80″
TYPE 7080
(EPOXY ENCAPSULATED VERSION)
NOTES:
(for both types)
1. INDUCTANCE measured on QuadTech/GenRad 1659 RLC Digibridge at
1.0 KHz. (Value less than 10 µH are measured at 10 KHz).
2. CURRENT RATING (Rated IDC) is based on 0.25 watt power dissipation
for approximately 20°C temperature rise. Depending on the application,
these units may be operated at up to twice the rated current.
3. INCREMENTAL CURRENT (INCR I) is the minimum current at which the
inductance will be decreased by 5% from its initial (zero-DC) value.
4. DIELECTRIC WITHSTANDING VOLTAGE: 1000 VRMS
5. OPERATING TEMPERATURE RANGE: -55° to +105°C.
6. Materials:
Coil Form: Ferrite
Cover: TYPE 7070 - Per MIL-I-23053/5, Class 1.
Flame Retardant IAW UL 224, Class 1.
TYPE 7080 - Epoxy encapsulated.
Magnet Wire: Per FED SPEC J-W-001177/9
