A21ASQ12VDC1.6 Electronic Components Series
Relay Automotive Terminal shape: Quick Connect Contact Arrangement: SPST N.O. Coil voltage: 12 VDC Current: 40 A Operating Function: Single Side Stable Sealing Options: Sealed Coil Power: 1.6 W Coil Suppression: 2 diodes (1N4005)
If you're working on automotive applications that require a robust, sealed relay with a quick connect terminal, the A21ASQ12VDC1.6 series from Citizen Electronics is a solid choice. These relays are designed to handle up to 40 A, making them ideal for high-current applications such as power windows, seat motors, or HVAC systems. The SPST (Single Pole Single Throw) Normally Open (N.O.) configuration ensures that the circuit is open until the coil is energized, providing a clean switching solution.
One thing worth noting is the variety of sealing options available. The standard model features a sealed design, which is crucial for protecting the relay from environmental contaminants in harsh automotive environments. The different suppression options—using either a diode or a combination of a diode and resistor—help protect the relay from voltage spikes and inductive kickback, ensuring reliable operation over time.
Engineers tend to reach for these relays when they need a reliable switching mechanism that can handle significant current loads and operate in a sealed environment without compromising on performance. The additional suppression components provide an extra layer of protection, making these relays particularly suitable for mission-critical automotive systems where reliability is paramount.
