The ARA200A03 is a sealed, high-frequency relay featuring 2 Form C contacts rated for 3V DC operation with single-side stable configuration. It is designed for RF and microwave applications with 50O impedance and operates reliably up to 1 GHz, delivering 3W carrying power with maximum insertion loss of 0.3dB and minimum isolation of 20dB between open contacts. The relay exhibits low profile dimensions of 9.7mm (W) × 14.7mm (L) × 5.9mm (H) with surface-mount terminals optimized for microstrip line circuit designs. Key electrical characteristics include maximum contact resistance of 75mO, maximum switching voltage of 30V DC, maximum switching current of 1A DC, and a nominal operating power of 140mW. The relay is ideal for measurement and communication applications such as oscilloscope attenuator circuits and antenna switching systems, offering high contact reliability with minimum electrical life of 107 cycles at 10mA 10V DC.
