Electronic Systems Protection furse

ESP PCB/06D, ESP PCB/15D, ESP PCB/30D, ESP PCB/50D & ESP PCB/TN PCB mount for data, signal and telephone lines

Suitable for "through hole" mounting directly onto the PCB of data communications, signal or telephone equipment.
Available for working voltages of up to 6, 15, 30 and 50 volts and telephone systems with a maximum working or ringing voltage of 190 volts.

For wire-in, twisted pair signalling applications, see the ESP **D range. For systems requiring a PCB mounted protector with a very low resistance , higher current or higher bandwidth, see the ESP PCB/**E range.

Application

Use within OEM data communications, signal and telephone systems , where transient overvoltage protection needs to be integral to the unit.

Features and benefits

Suitable for wave soldering.

Low let-through voltage between all lines.

Provides repeated protection in lightning intense environments.

Low in-line resistance minimises unnecessary reductions in signal strength.

ESP PCB/**D

Two pin clean end and three pin line end to ensure correct insertion.

Simple earthing via central pin on line side.

ABS housing.

Installation

Connect in series, soldering pins direct onto PCB. Tracks to line and earth pins should be as wide as practical.
