TO-5 RELAYS

DESCRIPTION

The TO-5 relay, originally conceived and developed by Teledyne, has become

one of the industry standards for low-level switching from dry circuit to 1

ampere. Designed for high-density PC board mounting, the Series 712 relays

are some of the most versatile ultraminiature relays available because of their

small size and low coil power dissipation.

The following unique construction features and manufacturing techniques

provide excellent resistance to environmental extremes and overall high

reliability:

• All welded construction.

• Unique uni-frame design providing high magnetic efficiency and mechanical

rigidity.

• High force/mass ratios for resistance to shock and vibration.

• Advanced cleaning techniques provide maximum assurance of internal

cleanliness.

• Precious metal alloy contact material with gold plating assures excellent

high current and dry circuit switching capabilities.

The Series 712D relay has an internal discrete silicon diode for coil transient

suppression. The hybrid Series 712TN relay has an internal silicon diode and

transistor driver. The integrated packaging of the relay with its associated

semiconductor devices greatly reduces PC board floor space requirements as

well as component installation costs.

By virtue of its inherently low intercontact capacitance and contact circuit

losses, the 712 has proven to be excellent ultraminiature RF switch for

frequency ranges well into the UHF spectrum. A typical RF application for the

TO-5 relay is in handheld radio transceivers, wherein the combined features of

good RF performance, small size, low coil power dissipation and high reliability

make it a preferred method of Transmit-Receive switching (see Figure 1).
