Control Line HEMP/TEMPEST Filter

At Captor Corporation, we developed a custom Control Line HEMP/TEMPEST Filter to protect control lines within a hardened system against electromagnetic pulse (HEMP) and compromising emissions (TEMPEST).

The OEM needed a solution that would:

Provide attenuation levels required to meet HEMP protection criteria

Satisfy TEMPEST emission control standards

Integrate into a defined enclosure and connector configuration

Maintain structural and electrical integrity in a high-reliability environment

We collaborated with the customer to translate compliance requirements into electrical filter design, mechanical packaging, and manufacturable assembly processes. Our engineering team assessed electrical performance, mechanical packaging, and environmental factors early in development to minimize qualification risk. The filter was designed specifically for the control line application, not adapted from a standard product.

This project demonstrates Captor’s disciplined approach to EMI filter fabrication for secure platforms. We integrate electrical design, mechanical engineering, and production control to ensure compliance from concept to manufacturing.

FT-8367 Feed Thru Capacitor

At Captor Corporation, we worked with a customer who required a custom feed-through capacitor that provided consistent attenuation and fit within a sealed, mechanically constrained system. The OEM needed a compact, high-reliability component that maintained EMI attenuation under operational stress.

We designed and manufactured the FT-8367 Feed Thru Capacitor to:

Maintain consistent attenuation across specified frequency ranges

Withstand mechanical and environmental stressors

Maintain long-term electrical stability

Integrate into a shielded housing without compromising performance

Our engineering team worked closely with the customer to align electrical specifications with packaging constraints. We validated through environmental and electrical testing aligned with application requirements.

This project highlights Captor’s expertise in precision EMI filter fabrication and component-level performance control.

Circuit Protection Device

At Captor Corporation, we developed a custom Circuit Protection Device to protect sensitive electronic systems from overcurrent and transient conditions within a constrained mechanical footprint. The application required precise electrical protection while integrating with the customer’s broader assembly.

The OEM needed a device that would:

Protect critical components from overcurrent and transient electrical events

Integrate into an existing system architecture without redesigning surrounding hardware

Maintain performance in a high-reliability operating environment

Support validation, qualification, and repeatable production

Our engineering team collaborated with the customer to define electrical thresholds and mechanical requirements early in development. We evaluate protection thresholds, response characteristics, integration constraints, and packaging constraints to ensure the device will function as intended in the field.

Instead of providing a standard solution, we engineered a circuit protection device tailored to the application. This project demonstrates our ability to combine electrical protection expertise with mechanical integration and production control. When OEMs need a solution engineered for their platform, we deliver both technical depth and manufacturing reliability.

Electromechanical DC Booster Assembly

At Captor Corporation, we developed a custom Electromechanical DC Booster Assembly to deliver a stable DC voltage output under defined load and environmental conditions within defined mechanical and environmental parameters. The project required precise electrical integration and disciplined mechanical assembly for long-term reliability.

The OEM required an assembly that would:

Deliver consistent DC voltage performance under specified load conditions

Integrate into an existing system architecture without expanding the footprint

Maintain stability across environmental and operational demands

Support validation, testing, and production scalability

We approached the project as a fully integrated build. Our engineering team aligned electrical circuitry, mechanical housing, and internal interconnects to ensure stable performance in the field. Early collaboration with the customer reduced design risk and ensured the booster assembly met performance and manufacturability goals.

The final product delivered consistent output performance while fitting within the system’s dimensional and structural constraints.

Custom Electromechanical Assemblies

At Captor Corporation, we design and manufacture custom electromechanical assemblies for OEMs requiring tightly integrated electrical and mechanical solutions. These projects often involve complex builds where filtering, power management, circuit protection, and mechanical packaging operate together within a defined system architecture.

In these applications, customers typically require:

Integrated electrical and mechanical functionality within strict dimensional constraints

Reliable performance in demanding operational environments

Controlled assembly processes to ensure repeatability

Documentation and traceability aligned with high-reliability standards

We begin each project with collaborative engineering discussions to fully understand system-level requirements. We evaluate how electrical components, housings, interconnects, and shielding work together to achieve the required performance, engineering the assembly as a unified system.

These custom electromechanical assemblies often incorporate EMI filter fabrication, circuit protection devices, feed-through capacitors, and other specialized in-house components. By managing both engineering and manufacturing, Captor ensures each assembly meets performance and reliability expectations.

These projects demonstrate Captor’s role as a design and manufacturing partner for complex, high-reliability systems. We serve as a technical partner to OEMs developing platforms that require precision, compliance, and long-term dependability.
