Designed expressly for high-density PC board mounting, its small size and low coil power dissipation make the 432 relay one of the most The Series 432D and 432DD relays have internal discrete silicon diodes versatile ultraminiature relays available. for coil suppression and polarity reversal protection. The hybrid 432T relay features an internal silicon suppression diode and transistor driver. This The following unique construction features and manufacturing techniques hybrid package reduces required PC board floor space by reducing the provide excellent resistance to environmental extremes and overall high number of external components needed to drive the relay. reliability. By virtue of its inherently low intercontact capacitance and contact circuit The 432 feature: losses, the 432 relay has shown its worth as an RF switch for frequency All welded construction. ranges well into the UHF spectrum (see Figure 1). In addition, the Unique uni-frame design providing high magnetic efficiency and sensitive Series 432 relay has a high resistance coil, thus requiring mechanical rigidity. extremely low operating power (200 milliwatts, typical at room High force/mass ratios for resistance to shock and vibration. temperature). The advantages of reduced heat dissipation and power Advanced cleaning techniques provide maximum assurance of internal supply demands are a plus. cleanliness.
