Surface Mount Pot Core Inductor
The Surface Mount Pot Core Inductors manufactured by Engineered Components Company are designed for RF/low power applications
utilizing low-loss ferrite core material. The pot core inductor design shields and isolates the winding from stray magnetic fields and
effects from the surrounding circuit elements.
The standard inductance value tolerance is +/-10% when measured at the frequencies listed (see Table 1). Inductance values and
Q values are measured on an HP 4284A LCR meter. Since inductance values vary with AC/DC current values, each end application should
be evaluated to ensure proper readings. The tabulated current ratings are those calculated to cause a 25 deg. C rise in case
temperature. These pot core inductors are designed to meet the applicable portions of MIL-C-15305, Grade 1, Class B. Temperature
coefficient of inductance is less than 400ppm/deg. C over the operating temperature range of -30 to +70 deg. C. Inductors are capable
of withstanding 500Vdc @ 50 uA applied between the coil and the case.
The inductor and the four phosphor-bronze leads (tin-lead plated) are mounted on a Liquid Crystal Polymer platform, off-white in color,
and secured in epoxy resin by utilizing a black Diallyl Phthalate case. Finished inductor sizes are shown in Table 2. Any exposed pot core
is coated with a conformal coating. Marking, applied by Laser Label, designates one coil termination lead with an indicator dot (see
Figure 1). The opposite lead is also a coil temination lead, while the leads at 90 deg. locations are no-connection mounting leads.
