Power Inductors

iNRCORE offers a wide variety of inductor sizes and current ratings. Shielded drum core inductors incorporating 4 ruggedized PCB mounting clips have superior performance in applications with shock and vibration requirements. SLIC, SLED and POGO series toroid power inductors have ruggedized construction. Planar inductors meet the demanding requirements for low inductance high DC current.

Gate Drive Transformers

iNRCORE’s gate drive transformers are ruggedized to meet MIL-PRF-27 Grade 5 requirements. iNRCORE offers Functional and Basic insulation. Reinforced insulation is available upon request.

Current Sense Transformers

iNRCORE’s current sense transformers have an additional clip for secure core halves bonding. Current ratings up to 35A are available. Custom designs are available on request.

Planar Transformers

iNRCORE’s high frequency planar transformers and inductors incorporate 2 additional clips for secure board mounting, which have superior performance in applications with shock and vibration requirements. iNRCORE can provide custom design services, as well as perform specialized screening and qualification testing.



iNRCORE’s high-frequency baluns are designed for SMPTE-292M and SMPTE-424M/425M applications, as well as standard testing equipment. They transform 50Ω / 75Ω grounded unbalanced signals to 100Ω /150Ω balanced differential signals and vice versa. Discrete surface mounting components and connectorized modules are available.

MIL-STD-1553 Data Bus Couplers

iNRCORE’s MIL-STD-1553 Data Bus Couplers are developed for bench test applications. They integrate MIL-STD-1553 transformers per MIL-PRF-21038/27 and 58.5 Ω non-inductive resistors. iNRCORE’s couplers are available in 1, 2, 3 or 4 stubs.

Data Isolation Transformers

iNRCORE’s CopperheadTM Series Data Isolation Transformers support a variety of data transmission and receiving applications. The data rate ranges from 265 Mbps to 3200 Mbps. These parts integrate single or dual transformer in one compact package.

Delay Lines

iNRCORE offers non-QPL passive delay lines per MIL-PRF-83531 and QPL active delay lines per MIL-PRF-83532. Standard total delay values range from 25nS to 500nS and tap delay values from 5nS to 100nS. SIP, DIP, SMT packages are available.

Ethernet Transformers

iNRCORE’s discrete Ethernet Transformers are ruggedized in transfer molding or pour-filled construction to meet MIL-PRF-21038 environmental requirements. They support various Ethernet protocols, including AFDX (Avionics Full Duplex Switched Ethernet), TTE (Time-Triggered Ethernet), and IEEE 802.3x – including PoE (Power over Ethernet).

MIL-STD-1553 Transformers

iNRCORE’s QPL and Non-QPL MIL-STD-1553 transformers are designed, built, and tested to MIL-PRF-21038, and they support all major 1553 transceivers with short stubbed and/or long stubbed communication via a MIL-STD-1553 data bus. iNRCORE has the most complete MIL-STD-1553 transformer line on the market, with various packages, configurations, and product testing levels available.
