Extremely Compact Lightning Arrestor Ideal for Mounting Inside Radio Chassis – New Product Release – PTCTNFMMFxxS

We are excited to announce the release of a brand-new Coaxial Arrestor design, the PTCTNFMMFxxS series of compact GDT arrestors.  Just like other examples of NexTek’s compact arrestor options, this unit is perfect for chassis-mount applications where space is at a premium…But at the same time, it provides heavy duty, military grade protection for your equipment and will not cost much more than a high-quality connector!

If you are looking for coaxial protection that does not cost you any more space and weight than absolutely necessary, perhaps because you’d prefer to integrate protection into the Radio Chassis itself, then you really have to check out this new design!

The PTCTNFMMFxxS-series coaxial arrester provides effective protection in an extremely compact form factor, and MMCX connectors for the lowest-profile connection.

PTCTNFMMFxxS OutlineAvailable with a TNC (f) bulkhead and MMCX (f) connectors, in a range of Protection Voltage/RF Power ratings.  See below and explore the datasheets to learn additional details!


Features:

  • DC to 6GHz Operating Band
  • Excellent Response and Residual Energy Reduction
  • Compact TNC to MMCX Bulkhead Protector
  • Low VSWR and Insertion Loss
  • Multi-strike, Rugged and Waterproof
  • Available in Multiple Protection Voltages: 90, 150, and 230V

Featured Transient Threat Type/Application: Static [ESD] Protection for Coaxial RF Lines

Today’s post highlights a type of Transient Threat that NexTek arrestors provide protection against.  Although Lightning energy is the primary source of damage to coaxial lines and systems where they are used, there are also other types of Surge Energy that can cause damage to electronics.

Baytems_ESDzap_and_EUTESD, or Electro-Static-Discharge, discharges can reach many kilovolts in potential and therefore could cause significant damage to most unprotected electronic equipment.  Although the total energy contained within an ESD discharge is relatively low, it is the fast risetime and kilovolt+ voltage potential that are the main causes of damage.

For any application or system which uses coaxial transmission cables and connectors, there is likely to be some risk of direct human contact to an “exposed” (i.e. un-mated) coaxial center pin which in-turn makes ESD discharges directly onto the center pin quite likely.  In this case, protection must be installed or afforded in order to ensure the continued performance of a given system or piece of equipment.

When examining a specific application and quantifying the ESD threat level, there are two main paths to travel down:  One, the ESD threat may be given by a specific Industry Standard document (MIL-STD, IEC, IEEE, EN, etc) according to a judgement made upstream in the overall program…or an approximate threat level or desired protection level based on the program-level design requirements.

See below for a table which lists some ESD Requirements which may apply:

Standards that require ESD testing include:

  • ISO 10605
  • Ford EMC
  • ISO/EN 61000-4-2 needed for the CE mark
  • IEC 61000-4-2
  • ISO TR10605
  • MIL-STD-883
  • MIL-STD-1512
  • GR-78-CORE
  • RTCA DO 160
