Quell product offering
Product offeringCore offering
Quell designs and manufactures custom EMI/RFI filter inserts and transient/ESD protection components built around its patented EESeal® silicone elastomer technology. The products retrofit into existing standard electrical connectors without requiring connector hardware changes, embedding passive filter and suppression components in a silicone substrate. These are sold to military, aerospace, space, and medical equipment manufacturers to resolve post-design EMI compliance and signal integrity issues.
Product overview
Quell Corporation offers the EESeal® product line, a family of EMI/RFI filter insert solutions that retrofit into existing electrical connectors without hardware or layout changes. The core product line consists of five distinct offerings: (1) EESeal® — the original EMI filter insert providing custom passive component filtering from 10kHz to 40GHz with 40–45dB attenuation; (2) EESeal+® — a high-frequency variant using high dielectric constant silicone achieving filtering up to 100GHz with 45–50dB attenuation; (3) ESDSeal™/TransSeal — transient voltage suppression and ESD protection inserts with TVS diode arrays and varistors; (4) EMI Gaskets — conductive/non-conductive elastomer gaskets for connector-level EMI shielding and grounding; and (5) Filtered Connector Solutions — behind-panel PCB-mounted filtering for standard connectors. Supporting these is the EESeal Design Tool, a web-based configuration platform for generating validated filter designs. All products share Quell's silicone elastomer technology platform and are designed, built, and shipped from the U.S. (Albuquerque, NM) with custom samples in 1–2 days.

Quell competitors and assessment
Company assessmentBroad incumbents
- Glenair:
- Amphenol (Filtered Connector / MIL-STD lines): Large incumbent connector manufacturer offering integrated filtered and EMI-protected connectors (e.g., MIL-DTL-38999 with filtering) that overlap with Quell's EESeal and filtered connector products, though typically as part of a much broader portfolio.
- Smiths Interconnect: Established provider of high-reliability filtered and hermetic connectors for aerospace, defense, and space; competes head-on with Quell on board-level and connector-level EMI filtering for mission-critical platforms.
Direct peers
- Spectrum Control (API Technologies): Direct competitor in custom and standard EMI filtering, filtered connectors, and transient protection products serving aerospace, defense, and industrial customers with similar filter-connector and array solutions.
