Hybrid Pyramidal Absorbers

New Generation – Hybrid pyramidal RLT-250/RLT-450/RLT-650 (moulded), Hybrid pyramidal absorbers GDS300-H3 to GDS850-H3 (foam) can be rubber paint.

Overview

Hybrid Pyramidal absorbers are designed specifically for the use over ferrite tiles. The resistive doping is far less than normal pyramidal absorbers and is very specific.

Global EMC offer two different types of Hybrid pyramidal absorber:

  1. RLTxxx range
  2. GDSxxx-H3 range

All products meet NRL8093 parts I, II and III fire safety.

GDSxxx-H3 - This is the doped foam type, used for many years and has proved to be fully compliant in CISPR16-4-1 3m, 5m and 10m EMC test chambers. This traditional option is more cost effective.

RLT250/RLT450/RLT650 – This NEW product is a solid homogeneous resistive doped polystyrene system. This product has some major advantages:

  1. Zero shedding (to clean room standard)
  2. Precise fit and gap-less fit
  3. Extended life span
  4. Damage resistant
  5. Cleanable
