Telecom Relay DPDT (2 Form C) Surface Mount
Active422 in stock

Overview

The TQ2SA-5V-Z is a high-sensitivity, low-profile DPDT signal relay designed for telecom and instrumentation applications. This surface-mount component features a 5VDC non-latching coil and silver nickel contacts with gold plating for reliable low-level signal switching. It is fully sealed to allow for automated cleaning processes after soldering.

Why Choose This Part

This relay offers a fast 4ms operate and release time with a compact 9mm by 14mm footprint. The gold-clad silver nickel contacts ensure high reliability for low-level signals, while the sealed construction protects against environmental contaminants.

Applications

Telecom Switching
Used in telephone exchange equipment and transmission systems for signal routing.
Test and Measurement
Ideal for data acquisition systems and automated test equipment requiring low thermal EMF.
Industrial Control
Provides galvanic isolation for low-power signal paths between controllers and sensors.
Medical Instrumentation
Utilized in patient monitoring devices where reliable small-signal switching is required.

Getting Started

When designing for the TQ2SA-5V-Z, ensure a 5VDC supply capable of providing at least 28.1mA for the coil. Use a standard flyback diode across the coil to protect driving circuitry from inductive spikes. For PCB layout, follow the 2.54mm pitch SMD footprint to maintain proper isolation distances.
