Polymer Resettable Circuit Protector "P.R.C.P. Series"

Polymer Resettable Circuit Protector "P.R.C.P. Series"

Resettable / Fast rise time of the cutoff characteristics / Flame retardant UL94V-0 / RoHS compliant, UL, CSA, TUV certified products

The P.R.C.P series is a resettable overcurrent protection device using a polymer PTC thermistor. By removing the cause of the overcurrent, it can be used repeatedly. Additionally, the time until current interruption is moderately delayed, preventing malfunctions due to surge currents or inrush currents, making it ideal for live insertion interfaces such as Plug and Play.

BOURNS Road Dump Surge Protection Proposal

BOURNS Road Dump Surge Protection Proposal

Due to changes in international standards, the voltage range has been expanded and the testing conditions have become stricter. The protective element SM8SF-Q is compliant with the new standards and is a compact product.

The SM8SF-Q is ideal for those seeking a smaller size of 8.1X10.5X1.3mm and a lower profile compared to the competing product DO-218 size (10.5X16X5mm). It can be replaced using the same recommended pad layout as the competing product, allowing for a drop-in replacement without the need for PCB modifications. We also offer the same DO-218 type, so please consider it.

Introduction of Bourns products for Single Pair Ethernet (SPE).

Introduction of Bourns products for Single Pair Ethernet (SPE).

Introducing products from Bones, a manufacturer of passive components such as circuit protection devices, inductors, and resistors, available for use with single-pair Ethernet.

As the market for the single-pair Ethernet standard IEEE802.3cg, which is attracting attention for its miniaturization and reduced wiring as an IoT Ethernet solution, progresses, we would like to introduce LAN transformers suitable for single-pair Ethernet transmission circuits from Bones, various common mode chokes for signal noise countermeasures, TVS diode arrays for electrostatic discharge protection, and differential choke coils for power lines when used as PoE. You can watch the archived video of the "Next Generation Communication Standard Single Pair Ethernet (SPE) Free On-Demand Seminar" hosted by Global Electronics at the URL below.
