Holland Shielding offers EMI and RFID absorber products for applications that need to reduce electromagnetic noise, manage RF behavior, or control interference around devices, metal surfaces, and test environments.
For buyers comparing absorber brands, Holland Shielding is worth reviewing when a project may require more than one absorber format. Its lineup includes hybrid pyramid absorbers for compact chambers, non-flammable high-power absorbers for anechoic chambers, and flexible EMI absorber sheets for local noise suppression.
Holland Shielding’s absorber category covers several approaches to EMI, RFID, and RF-related problems. Some products target local noise sources inside electronic devices, while others support larger spaces such as anechoic chambers and EMC test environments.
That distinction matters because an “absorber” is not a single material format. A flexible sheet, a hybrid pyramid absorber, and a high-power chamber absorber each solve a different placement and frequency-control problem. Start by identifying where the absorber will be installed, then narrow the product type by frequency range, material format, power handling, and installation conditions.
Holland Shielding lists many absorber products, but buyers do not need to review the full catalog to understand the brand’s absorber range. These three products provide a practical first look at its absorber lineup.
| Product | What it represents | When to check it |
|---|---|---|
| 3630 Wide-Band Hybrid Pyramid EM Absorbers | Absorber for compact anechoic chambers | the project requires wide-band absorption from 30MHz to 18GHz. |
| 3680 Non-Flammable High-Power Absorbers | Absorber for high-power anechoic chambers | the project requires flame-retardant absorber material, high-power handling, and broadband microwave absorption. |
| 5780 Flexible EMI Absorber Sheets | Absorber for local noise suppression | the absorber needs to fit inside a device, near a noise source, around RFID/NFC components. |
These examples show the breadth of Holland Shielding’s absorber range without turning the page into a product catalog. Use them as starting points, then confirm the exact series, dimensions, material requirements, and frequency range with Holland Shielding before requesting a quote.
The 3630 Wide-Band Hybrid Pyramid EM Absorbers are designed for wide-band absorption in small anechoic chambers. They combine ferrite and carbon powder materials and are tuned for use over ferrite absorber tiles, helping extend chamber performance from 30 MHz to 18 GHz.
Holland Shielding describes the 3630 series as an 80 mm high absorber with a 200 mm × 200 mm base. Its low-profile pyramid design helps preserve internal room space compared with larger foam pyramid absorbers, making it useful when a compact chamber needs more usable test space.
The 3680 Non-Flammable High-Power Handling Absorbers are designed for high-power microwave absorption in anechoic chambers. They use a hollow broadband structure made from heat-resistant non-woven fabric impregnated with flame retardants and microwave absorbing agents.
Holland Shielding describes these absorbers as suitable for microwave anechoic chambers, including applications where test equipment inside the chamber needs shielding. The absorbers support broadband performance under both normal and oblique incidence conditions, while also providing scattering attenuation and isolation performance.
The 5780 Flexible EMI Absorber Sheets are designed for electromagnetic-wave absorption and noise suppression close to the source. They can be attached directly to parts that generate or receive unwanted noise, making them useful when the interference problem sits inside a product rather than across an entire room or chamber.
Holland Shielding describes these sheets as flexible, easy to handle, self-adhesive, and available in custom shapes, sizes, and thicknesses. They can also be cut to customer drawings, which helps when the absorber must fit around a PCB, IC, processor, controller, cable, housing, RFID antenna, NFC module, or wireless charging layout.
Select Holland Shielding absorbers based on the target frequency range, installation environment, and whether the main requirement is compact chamber performance, high-power microwave absorption, or local device-level noise suppression.

| 5780 Flexible EMI Absorber Sheets | 1 MHz to 18 GHz | Electromagnetic-wave absorption, noise suppression, magnetic flux path control, and eddy current reduction near metal | Custom shapes, sizes, and thicknesses; cut-to-drawing options available | Flexible EMI absorber sheet; C1/C3/C6/C6B soft rubber type and C7 flexible sintered ferrite sheet structure | RFID, NFC, WPC/Qi wireless charging, PCBs, ICs, processors, controllers, EMI shielding boxes, and flexible cables |
The 3630 Wide-Band Hybrid Pyramid EM Absorbers are suitable for small anechoic chamber applications that need wide-band absorption from approximately 30 MHz to 18 GHz. Their low-profile pyramid structure helps save internal chamber space compared with larger foam pyramid absorbers, making them useful for compact EM-wave chambers, antenna chambers, and GHz-band testing environments.
The 3680 Non-Flammable High-Power Handling Absorbers are suitable for high-power anechoic chamber applications that require flame-retardant absorber material and broadband microwave absorption. Their non-woven fabric structure is impregnated with flame retardants and microwave absorbing agents.
The 5780 Flexible EMI Absorber Sheets are suitable for local noise suppression inside electronic devices. They can be attached near noise sources and shaped for compact layouts, making them useful for RFID, NFC, WPC/Qi wireless charging, PCBs, ICs, processors, controllers, housings, EMI shielding boxes, and flexible cables.
The RF absorber market is expanding rapidly, driven by the increasing need for EMI (Electromagnetic Interference) reduction in 5G/6G, autonomous driving, and defense applications.

Holland Shielding is worth including in the absorber comparison when the project needs a clear choice between device-level noise suppression and chamber-focused RF-control materials. Its representative products show three routes: 3630 hybrid pyramid absorbers for compact anechoic chambers, 3680 high-power absorbers for non-flammable chamber applications, and 5780 flexible EMI absorber sheets for local noise suppression in compact device layouts.
For RFID, NFC, wireless charging, PCB, IC, processor, controller, and cable applications, start with the 5780 Flexible EMI Absorber Sheet series. For small chamber applications, review the 3630 Wide-Band Hybrid Pyramid EM Absorbers. For high-power anechoic chambers, compare the 3680 Non-Flammable High-Power Handling Absorbers against the required power handling, fire retardance, frequency behavior, and installation conditions.
