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
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 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).
