TX2-3V
Overview
The TX2-3V is a 2 Form C (DPDT) low signal relay designed for high sensitivity and high dielectric strength in a compact PCB-mount package. It features gold-clad silver contacts and a sealed construction, making it ideal for precision switching of low-level signals up to 2A. This non-latching, single-side stable relay is rated for a 3V DC coil voltage and offers high surge resistance between contacts and coil.
Why Choose This Part
The TX2-3V provides a high dielectric strength of 2,000 Vrms between the coil and contacts and can withstand surges up to 2,500 V. Its sealed design allows for automatic cleaning after soldering, while the 3V coil only requires 46.7 mA, making it compatible with low-voltage logic circuits.
Applications
Key Specifications
Getting Started
When designing with the TX2-3V, ensure a flyback diode is placed across the coil to protect driving transistors from inductive spikes. The 10-pin through-hole layout follows a standard signal relay footprint; refer to the Panasonic footprint diagram to ensure correct orientation of the polarized coil. No specific software is required, but it can be driven directly from an MCU via a standard NPN or N-Channel MOSFET driver stage.
