DESCRIPTION
INTERNAL CONSTRUCTION
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 expressly
for high density PC Board mounting, its small size and low coil power dissipation make
the TO-5 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 432D and 432DD Series utilizes internal discrete silicon diodes for coil suppression
and polarity reversal protection. The hybrid 432T features an internal silicon suppression
diode and transistor driver. This hybrid package reduces 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 TO-5
relay has shown its worth as an RF switch for frequencies well into the UHF spectrum (see
Figure 1). In addition, the sensitive 432 Series relay features exceptionally high coil
resistance thus providing for extremely low operating power (200 milliwatts typical at room
temperature). The advantages of reduced heat dissipation and power supply demands are
obvious.

NOTES:
Relays can be supplied with a spacer pad attached to
the relay header. The pad permits the relay to be
spaced away from the mounting surface facilitating
solder joint inspection. To order add M4 to the part
number (e.g. ER432M4-26A).
1. Material: Polyester film.
2. Increase contact resistance
by 0.01 ohm.

Relay contacts will exhibit no chatter in excess of 10 µsec or transfer in excess of 1 µsec.
“Typical” characteristics are based on available data and are best estimates. No on-going verification tests are performed.
For reference only. Coil resistance not directly measurable at relays terminals due to internal series semiconductor. 432DD and 432T only.
Screened HI-REL versions available. Contact factory.
Unless otherwise specified, relays will be supplied with leads as follows: Length will be standard 0.75” (19.05) minimum and will be either
gold plated or solder coated. Contact your local representative for ordering information.
The slash and characters appearing after the slash are not marked on the relay.
Limit Base Emitter current to 15 mADC.
Unless otherwise specified, parameters are initial values.
Circuit is typical for all 432T Series. Values shown are for the 5 volt series and apply over the full operating temperature range.
