Military QPL Approval
M27/368 T Level, Grade 5, encapsulted
Level T Magnetics are 100% Tested per MIL-PRF-27
Group A Subgroup I which includes:
1) Thermal Shock, 25 cycles
2) Burn In, 96 hours
3) Radiographic (X-Ray) Inspection
Operating Temperature Range –55°C to +130°C
Current Rating at 90°C Ambient 40°C Rise
Maximum Power Dissipation at 90°C 0.278 W
Inductance Measured at 1VAC with no DC current
Incremental Current The current at which the
inductance will decrease by a maximum of 5% from
its inductance at zero DC current.
Lead Finish
Sn63 Pb37 (Tin-Lead)
Hot Solder Dipped
Weight
0.1 grams MAX
Mechanical Configuration Inductors are encapsulated in a Surface Mount
package, using an epoxy molded case. Leads are pretinned. A high resistivity
ferrite core allows for high inductance with low DC resistance.
