Series 12-32 Thread Hermetically Sealed Circuits Available
series offers effective filtering from GHz. Glass sealed both ends hermeticity, this series impervious high moisture, solvents, other severe environmental conditions commonly encountered military applications. designed bulkhead mounting with lockwasher supplied. feedthru designs yield constant filtering current level increased from no-load full rated load. They most effective when placed high impedance circuits. designs exhibit sharper roll-off filter characteristic perform effectively when used medium impedance circuits. Alternate lead configurations special capacitance values voltage ratings ordered.

Notes
NOTE CAPACITANCE CODE
Filters part numbers, with exception certain cylindrical styles, show total filter capacitance using 3-digit code. first digits significant: last digit multiplier. Example: 103=10000 picofarads 125=1200000 picofarads (1.2 microfarads) important note that filters multisection filters described using code from standpoint total capacitance. Capacitance understood specified "guaranteed minimum value" (GMV) unless otherwise specified. Filters supply ±20% other specified tolerances additional charge. Contact Filters Applications Engineering further information.
NOTE VOLTAGE CODES FILTER VOLTAGE RATINGS
IMPORTANT: please contact Filters Applications Engineering when considering DC-rated filter designs possible applications. general rule, designs derated applications. assist you. voltage code letters must selected consistent with capabilities outlined product selection tables given filter type. important note that same code letter signify different voltage rating depending upon filter type. example: code signifies VDC/125 rating bolt-style filter, describes VDC/125 design when applied JD-style filter.
NOTE RELIABILITY CODES
customer must select reliability code consistent with filter application. minimum, catalog filters available R-level designs. Options: signifies R-level filter design without optional R-level high-rel screening R-level design with optional R-level high-rel screening also specified Class design with Group screening M28861 Class filters Class design with Group screening M28861 Class (space grade) filters Please refer catalog section Reliability additional information select reliability codes.
NOTE TERMINAL LEADWIRE CODES
Non-standard terminal configurations including special materials finishes available. Please indicate description and/or outline drawing when requesting non-standard terminal (code "3").
NOTE SPECIAL INFORMATION CYLINDRICAL STYLE FILTERS
L-section filter designs must specified with regard "standard" "reverse" configuration. L-section filter normally utilized with capacitor high impedance side circuit inductor looking into impedance side. Compact filter types such button filters with ferrite bead inductors only supplied with bead assembled into threaded end. L-section filters normally supplied with schematic other marking indicate location inductor. AC-rated catalog designs incorporate reduced values capacitance limit reactive current heating (and subsequent filter temperature rise) safe levels. specify DC-rated filter with larger capacitance application without contacting Filters Applications Engineering.
NOTE SPECIAL DESIGN CODE (ASSIGNED FILTERS)
special suffix standard part number will added Filters Applications Engineering describe special designs designs that controlled customer specifications. important note that even those instances where customer drawing describes standard catalog design Filters policy assign special part number customer drawing configuration control.
