API Delevan RF inductors are designed to provide optimal performance in high frequency analog circuits and signal processing in applications such as RFID, test equipment, GPS’s, radar, Wi-Fi, and satellite radios. Rugged, epoxy molded construction offers durability and moisture resistance in harsh environments. Tolerances down to +/-1% of nominal inductance, and shielded offerings (minimizing coupling to less than 2%) allow tighter assembly on valuable circuit board real estate. Standard operating temperature ranges are per MIL specs, -55°C to +125°C. Custom designs to meet any application specific requirements, and space level up-screening to MIL-STD-981C Group A and B are always available.

All API Delevan inductors are offered with termination options in RoHS compliant Tin-Silver-Copper (Sn96.5Ag3.0Cu0.5) over Copper (Cu), or Tin-Lead (Sn63/Pb37) over Copper (Cu) to support military applications.
