Zetex Intros SOD323 Packaged Varactor Diodes – ZMV830 & ZMV900 Series
Zetex (Commack, NY) introduced its new SOD323 packaged Varactor Diodes, which are claimed to offer the same high-performance operation as their larger SOT23 packaged alternatives. Zetex guarantees a minimum quality factor Q at test conditions of 50MHz and a low Vr of 3V or 4V. The Hyperabrupt ZMV830 Series of SOD323 Tuners offer a nominal capacitance range between 8.2pF and 68pF for a Vr of 2V and a frequency of 1MHz. The ZMV900 series of High Ratio Hyperabrupt Varactor Diodes are claimed to demonstrate a much faster change in capacitance for a given change in bias voltage. The mid-range ZMV933 device provides capacitance of 42pF at 1Vr, falling to 12pF as bias rises to 4V. Breakdown voltage for the product range is 12V. Pricing for the new devices ranges from $0.46 to $0.54 each, in quantities of 5,000.
