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, its small size and low

coil power dissipation make the 431 relay one of the most versatile

ultraminiature relays available.

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

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

• Advanced cleaning techniques provide maximum assurance of internal

• Precious metal alloy contact material with gold plating assures excellent

The Series 431D and 431DD relays have internal discrete silicon diodes for

coil suppression and polarity reversal protection. The hybrid 431T relay

features an internal silicon suppression diode and transistor driver. This hybrid

package reduces required PC board floor space by reducing the number of

external components needed to drive the relay.

By virtue of its inherently low intercontact capacitance and contact circuit

losses, the 431 relay has proven to be an 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 T-R switching (see Figure 1).
