Model 303M Hybrid 5-Pin Protector Modules
The Bourns
®
Hybrid 5-Pin Protector Module design combines solid-state semiconductor technology and gas tube technology. The
hybrid protector (gas tube with coordinated MOV) provides the fastest response to damaging overvoltage transients as well as high
energy handling capability.
The hybrid design technology provides optimum overvoltage protection for both primary and secondary protection applications. Since
the hybrid is designed as a 5-pin configuration, it can easily be interchanged with all other standard 5-pin protectors.The hybrid design
also includes a fail-safe mechanism that operates under sustained or high-current power cross conditions to permanently short the line
to ground.
The hybrid design provides protection for data transmission over copper pairs. The solid-state semiconductor technology combined with
the gas tube technology will allow the hybrid protector to respond quickly to protect sensitive equipment.The hybrid is ideal for
providing protection for broadband voice and data circuits (ADSL, ADSL 2+, VDSL2) due to its solid-state speeds and low capacitance.
The Bourns
®
Hybrid 5-Pin Protector Module is also available with an option for a positive temperature coefficient (PTC) device to
provide resettable sneak current protection.This feature protects digital equipment line cards against overheating caused by prolonged
currents (commonly called sneak currents). Sneak currents are often caused by direct contact with low-voltage power lines; they may
result from induction on telephone lines caused by fault currents, overloads or unbalanced loads on nearby power lines. The Bourns
®
Hybrid 5-Pin PPTC Resistor Module is unique in design because it has minimal signal loss in the ADSL, ADSL 2+, VDSL, CAT 3 and
higher frequency ranges.
