All the Benefits of a Bulky Filtered Connector in a Slim, Cost-Effective Insert
Conductive silicone rubber of EESeal® fits over connector pins like a glove. Each pin in your connector is like a finger in the glove. We can treat each one uniquely with capacitors, resistors, MOVs, or other electronics to meet your project requirements.
Rapid prototyping and split-second installation tackle EMI/RFI problems pronto—all in an insert weighing under one gram.

MIL-STD-461 Radiated Emissions Problems
During testing, this connector demonstrated high EMI levels, with several surges above the spec level.
An EESeal® corrected the issue instantly, earning a passing grade.
Typical EESeal® Attenuation
Single Capacitor – Pin to Shell
Typical attenuation of a range of capacitors used in an EESeal.
Other capacitor values are also available. This includes Commercial grade, HiRel, Space, etc.
In this example the target frequencies were from 50-200MHz with a peak outage at 80MHz. Due to the differences in inductance between an EESeal and the EESeal+, a different capacitor value must be used. As you can see, the EESeal+ offers ~10dB of additional attenuation up and down the curve over the standard EESeal for this application.
Using the same capacitor in any EMI filter does not always give you the same performance. The attenuation using a discrete 4pF capacitor in an EESeal vs. the EESeal+ are very different. Integral capacitors can be used in the EESeal+ which have virtually zero inductance allowing for noise mitigation in the 10-100GHz range.
