INTERNAL CONSTRUCTION
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 732 relay is one of
the most versatile ultraminiature relays available because of its small size and
low coil power dissipation.

• 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 732D relay has an internal discrete silicon diode for coil transient
suppression. The hybrid Series 732TN 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 732 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 Transmit-Receive switching (see
Figure 1).

GENERAL NOTES
Vcc
1. Relay contacts will exhibit no chatter in excess of 10 µsec or transfer in
excess of 1 µsec.
2. “Typical” characteristics are based on available data and are best estimates.
No on-going verification tests are performed.
3. Unless otherwise specified, parameters are intial values.
4. For Reference Only. Coil resistance not directly measurable on 732TN relays.
5. Circuit is typical for all Series 732TN. Values shown are for 732TN-5 relay
and apply for full temperature range.Limit base-emitter current to 15 mADC.
6. Unless otherwise specified, relays will be supplied with either gold-plated or
solder-coated leads.
7. The slash and characters appearing after the slash are not marked on the
relay.
