Mouser Adds PolyPhaser RF Surge Protection Products

Why It Matters

The partnership gives designers immediate access to industry‑grade surge protection, reducing downtime and equipment loss from lightning or EMP events. It also strengthens Mouser’s position as a one‑stop source for critical communication components.

Key Takeaways

• PolyPhaser RF protectors cover 400 MHz‑2.5 GHz range
• Up to 40 kA surge rating for extreme lightning events
• Designed for Wi‑Fi, GPS, cellular and public‑safety networks
• IP67 and RoHS compliance meets stringent industrial standards
• Mouser distribution expands global availability to OEMs

Pulse Analysis

The rise of connected devices in public safety, autonomous vehicles and remote sensing has heightened the vulnerability of RF front‑ends to lightning strikes and electromagnetic pulses. When a surge penetrates a coaxial link, it can instantly destroy sensitive transceivers, leading to costly outages. Engineers therefore prioritize built‑in protection that can absorb high‑energy transients without degrading signal integrity, a need that drives demand for robust RF surge protectors across the communications ecosystem.

PolyPhaser’s new series addresses this demand with a blend of SASD, MOV and gas‑tube technologies, delivering up to 3 kW power handling and 40 kA surge capability. The GX line supports DC‑biased antenna systems up to 2.7 GHz, while the IS‑B50 targets HF/VHF/UHF radios with 20 kA rating and nuclear‑EMP compliance. The TSX and TUSX bulkhead models use a spiral architecture to maintain low insertion loss across 300 MHz‑2.7 GHz, making them suitable for cellular base stations and emergency response networks. All units are RoHS‑compliant and feature IP67 sealing, ensuring durability in harsh outdoor installations.

Mouser’s distribution agreement accelerates market penetration by leveraging its extensive global logistics network and design‑in tools. OEMs and system integrators can now source these protectors alongside complementary components, shortening BOM cycles and simplifying procurement. As 5G rollout and IoT expansion continue, the need for resilient RF pathways will only grow, positioning PolyPhaser’s surge protectors as a critical safeguard in next‑generation communication infrastructure.
