- Operation -55 to +125°C
DESIGN NOTES
Toroidal inductors described in this brochure are manufactured of the highest quality raw materials utilizing gapped ferrite cores; they are provided as semi-encapsulated units with thru-hole mount leads to realize maximum inductance per unit volume.
These toroidal inductors are designed to provide the utmost in versatility for power applications in computers, filters, instruments, missiles, aircraft, business machines, communications equipment and similar type applications. They are designed for printed circuit board applications; package design provides positive standoff to allow solder fillet formation and flush cleaning of solder-flux residue from under the component after the soldering operation.
The toroid mounts are molded from a liquid crystal polymer, (LCP) plastic. LCP can be used continuously at 280°C (536°F), has a melt point of 335°C (635°F), is inherently flame retardant and meets the flammability requirements of UL 94V-0. Leads are of copper; finish is hot 60/40 solder dipped. Inserts are manufactured from brass in accordance with specification QQ-B-626. Toroids are secured to the housing with epoxy resin.
These toroidal inductors are
designed to meet the applicable portions of Specification
MIL-PRF-15305, Grade I, Class B; they are designed for -55
to +125°C operation. Inductors are capable of withstanding
500 V DC @ 50 microamps applied between inductor to case.
Standard inductance tolerance
is ±10%,
however, units can be supplied to closer tolerances on special
order. All measurements of inductance are obtained at frequencies
as specified in Specification MIL-PRF-15305. Standard inductance
values are shown in the following table. Since inductance
varies with AC/DC current values, each end application should
be evaluated to ensure proper specification of inductance
value. Inductance is measured on HP 4262A and 4284A/42841A
LCR Meters.
Marking consists of manufacturer's logo (EC²), part number, terminal identification and date code of manufacture. All marking is applied by Laser label. Coil termination occurs at lead centered under label and at Pin 1 locator, all other leads are no-connection mounting leads.
