metal enclosure builds
As operating frequencies push deeper into the millimeter-wave range, traditional EMI and cavity resonance solutions begin to fall short. Designs above 30 GHz—especially in 5G, automotive radar, and high-speed wireless systems—require materials that can effectively absorb energy without adding bulk, contamination risk, or mechanical complexity.
That’s where ECCOSORB™ JCS-NEXT stands apart.
ECCOSORB™ JCS-NEXT is a dielectrically loaded silicone elastomer absorber engineered specifically for high-frequency noise above 30 GHz, extending well beyond 90 GHz. It was developed to address the unique challenges of modern mmWave electronics where space is limited and performance margins are tight.
Designed for the mm Wave Era
ECCOSORB™ JCS-NEXT uses a proprietary filler system that delivers more than twice the effectiveness of traditional dielectric or carbon-filled absorbers at millimeter-wave frequencies. The result is exceptionally high dielectric loss in a thin, flexible elastomer format—ideal for today’s compact RF designs.
Unlike brittle or particulate-shedding absorber materials, JCS-NEXT is dust-free, non-flaking, and mechanically robust, making it suitable for sensitive RF and microwave assemblies where contamination can degrade performance or reliability.
Key Performance Advantages of ECCOSORB JCS-NEXT
ECCOSORB™ JCS-NEXT is purpose-built for engineers working at the edge of frequency and form-factor limits:
-
Frequency range: 30–90+ GHz
-
Very high dielectric loss for effective EMI and cavity resonance suppression
-
Low-density, flexible silicone construction
-
Waterproof and environmentally stable
-
Wide service temperature range: –70 °C to 177 °C
-
UL 94 V-0 capable
-
REACH and RoHS compliant
These properties allow designers to reduce cavity Q, suppress surface currents, and damp parasitic resonances without redesigning enclosures or increasing mechanical complexity.
Typical Applications
ECCOSORB™ JCS-NEXT is commonly used in applications where conventional absorbers struggle at higher frequencies, including:
-
5G mmWave telecom and datacom equipment
-
Automotive radar systems (60 GHz and 76–81 GHz)
-
60 GHz wireless connectivity modules
-
Microwave amplifiers and oscillators
-
Antenna isolation and insertion-loss control
-
High-frequency cabinets and computer housings
-
Military and industrial RF systems
In these environments, JCS-NEXT helps reduce unwanted coupling, stabilize system performance, and control radiated noise at millimeter-wave frequencies.
Material Availability & Custom Die Cutting
ECCOSORB™ JCS-NEXT is available in standard sheet sizes with thicknesses ranging from 0.25 mm (.020” thk) to 3.0 mm (.125” thk), including common nominal options such as 0.5 mm (.020” thk), 1.0 mm(.040” thk), and 2.0 mm (.080” thk). The material is offered with or without pressure-sensitive adhesive, depending on installation requirements.
New England Die Cutting (NEDC) provides custom die cutting of ECCOSORB™ JCS-NEXT into complex, application-specific geometries. This allows engineers to place absorber material precisely where it is needed—inside cavities, around antennas, or near high-frequency noise sources—without excess material or wasted space. NEDC supports prototyping through production volumes for demanding RF and millimeter-wave applications.
Why ECCOSORB™ JCS-NEXT Matters
As frequencies continue to rise, EMI control becomes less about blanket shielding and more about precision absorption at the source. ECCOSORB™ JCS-NEXT gives designers a solution engineered specifically for millimeter-wave systems: thin, flexible, clean, and highly effective above 30 GHz.
For next-generation radar, wireless, and high-frequency electronics, this material is not an incremental upgrade—it’s built for where RF design is headed.
